“The Mission of the IAEA Department of Nuclear Sciences and Applications is to contribute to sustainable development in Member States through the use of nuclear sciences and their applications in food and agriculture, human health, industry, water resources management, and environment monitoring, research and protection, with due regard to safety”.

Executive summary The Chemistry Unit of the Physics, Chemistry and Instrumentation Laboratory in the IAEA's Seibersdorf Laboratory in Austria, has the programmatic responsibility to support global radionuclide measurement systems, in issues of international concern related to an accidental or intentional release of radioactivity in the environment. To fulfil this obligation and ensure a reliable worldwide, rapid and consistent response, the Chemistry Unit coordinates an international network of Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA). The network, established by the IAEA in 1995 [1] [2] [3], makes available to Member States a world-wide network of analytical laboratories capable of providing reliable and timely analysis of environmental samples in the event of an accidental or intentional release of radioactivity. The network is a technical collaboration of existing institutions. It provides an operational framework to link expertise and resources, in particular when a boundary-transgressing contamination is expected or when an event is of international significance. A primary requirement of the ALMERA members is participation in the IAEA interlaboratory comparison exercises which are specifically organized for ALMERA on a regular basis. These exercises are designed to monitor and demonstrate the performance and analytical capabilities of the network members, and to identify gaps and problem areas where further development is needed. Continued membership has benefits in training and educational opportunities, enhanced mutual trust in results and methodology and objective evidence for accreditation purposes.

The performance evaluation results of the interlaboratory comparison exercises performed in the frame of the ALMERA network are not anonymous for those laboratories nominating to participate as ALMERA members. In the interlaboratory exercise described in this report, 195 test samples (matrix reference materials) were prepared and distributed to the participating laboratories in June 2006. Laboratories were sent samples containing known activities of gamma emitting radionuclides in three matrices (soil, grass and water), and were requested to return the results within three days of receipt of the samples (short-term reporting). The participating laboratories were requested to analyse the samples employing the methods used in their routine work, so that their performance on the test samples could be directly related to the real performance of the rapid reporting. Thirty eight laboratories (Table 1) from sixty five initially registered laboratories, reported their results to the IAEA. The analytical results of the participating laboratories were compared with the reference values assigned to the reference materials, and a rating system was applied. Table 2 reports a summary evaluation of this proficiency test. The proficiency test results has demonstrated that in the case of 40K, 54Mn, 60Co, 65Zn, 134Cs, 137Cs and 241Am the majority of the participating laboratories could produce analytical results within acceptable time limit and which is satisfactory and comparable within the network. For these radionuclides the accepted results ranged between 70 to 95 %. The proficiency test results show that the determination of the activity concentrations of 109Cd and 210Pb were the most problematic and it was found that

6

more than 50 % of the participating laboratories should apply corrective actions to fulfil the acceptance criteria of this proficiency test. The analytical uncertainties associated with the reported results were, in general, appropriate for the analytes and matrices considered in the current proficiency test. It is recommended to repeat the same exercise to check if the laboratories were able to introduce proper corrective actions to improve the performance in the determination of 109Cd and 210Pb. Generally speaking, this exercise provided the possibility to quantify the level of analytical performance of the ALMERA network members and it is a step forwards the improvement of the network performance in the determination of gamma emitting radionuclides. Acknowledgement The participants and laboratories responded to this proficiency test and contributed their efforts to the present work are highly appreciated and acknowledged. The Hungarian Agricultural Authority, Food and Feed Safety Directorate, Central Radioanalytical Laboratory of Hungary contributed, as IAEA collaborating Centre, in the preparation and characterization of the grass reference materials used in this proficiency test.

1. Introduction The Chemistry Unit of the Physics, Chemistry and Instrumentation Laboratory in the IAEA's Seibersdorf Laboratory in Austria, has the programmatic responsibility to provide assistance to Member State laboratories in maintaining and improving the reliability of analytical measurement results, both in trace element and radionuclide determinations. This is accomplished through the provision of reference materials of terrestrial origin, validated analytical procedures, training in the implementation of internal quality control, and through the evaluation of measurement performance by organization of worldwide and regional interlaboratory comparison exercises. The use of reference materials and interlaboratory comparison exercises are among the most important tools for the production of reliable measurement results and for the achievement of a required quality level. Through the evaluation reports provided to the participating laboratories in the interlaboratory comparison exercises, the IAEA provides direct consultation and guidance on appropriate measurement techniques to be applied, and identifies gaps and problem areas where further development is needed. This helps participating laboratories to improve both their measurement techniques and performance. With the advent of “mutual recognition” on both a European and world wide basis, it is now essential that laboratories participate in proficiency testing schemes that will provide an interpretation and assessment of results which is transparent to the participating laboratory and its “customer”. The activities of the Chemistry Unit are also addressed to support global radionuclide measurement systems, in issues of international concern related to an accidental or intentional release of radioactivity in the environment. To fulfil this obligation and ensure a reliable

worldwide, rapid and consistent response, the Chemistry Unit coordinates an international network of Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA). The network, established by the IAEA in 1995 [1] [2] [3], makes available to Member States a world-wide network of analytical laboratories capable of providing reliable and timely analysis of environmental samples in the event of an accidental or intentional release of radioactivity. The network is a technical collaboration of existing institutions. It provides an operational framework to link expertise and resources, in particular when a boundary-transgressing contamination is expected or when an event is of international significance. A primary requirement of the ALMERA members is participation in the IAEA interlaboratory comparison exercises which are specifically organized for ALMERA on a regular basis. These exercises are designed to monitor and demonstrate the performance and analytical capabilities of the network members, and to identify gaps and problem areas where further development is needed. Continued membership has benefits in training and educational opportunities, enhanced mutual trust in results and methodology and objective evidence for accreditation purposes. The performance evaluation results of the interlaboratory comparison exercises performed in the frame of the ALMERA network are not anonymous for those laboratories nominating to participate as ALMERA members. In the interlaboratory exercise described in this report, 195 test samples (matrix reference materials) were prepared and distributed to the participating laboratories in June 2006. Laboratories were sent samples containing known activities of gamma emitting radionuclides in three matrices (soil, grass and water), and were

requested to return the results within three days of receipt of the samples (short-term reporting). The participating laboratories were requested to analyze the samples employing the methods used in their routine work, so that their performance on the test samples could be directly related to the real performance. Thirty eight laboratories from twenty nine different Member States participated in this exercise. 2. Materials and methods 2.1 Proficiency test objectives The measurement of water, grass and soil samples containing a mixture of radionuclides with an unknown (to the participants) composition was aiming at (i) checking the accuracy and precision of the analytical results produced by the participating laboratories from ALMERA network, (ii) testing the comparability of radiological measurements and (iv) encouraging the participating laboratories in finding remedial actions where shortcoming in analytical performance are detected.

2.2 Participants

A total of 65 laboratories were registered in this PT. 38 laboratories reported their results to the IAEA. A complete list of participants is given in Appendix D. 2.3 Composition and preparation of proficiency test materials

The following proficiency test design was applied: • one spiked soil sample (200g) • one natural grass sample (100 g) • one spiked water sample (500 ml) Table 4 presents the target values and the combined standard uncertainties of the PT samples.

2.3.1 Preparation of the spiked soil sample 01 A soil from China was used to prepare a spiked mineral matrix with 8 gamma emitting radionuclides. Table 3 shows the identification of certified solutions used in this PT. Before using the soil for spiking, it was milled and sieved to collect the appropriate fraction at mesh size less than 0.1mm, and then homogenised. The matrix of Chinese soil was characterised and a number of samples were pre-screened for radionuclides prior to spiking. The results have shown that the material is free from radionuclides, except for 137Cs, which was present at 2.6 ± 0.2 Bq kg-1 based on dry mass. (Ref. date: 2006-01-01). In addition, 210Pb was found at 48 ± 1.5 Bq kg-1 dry mass. The moisture content was found to be 2.3 ± 0.2 %. The preparation of the spiked soil sample was performed according to a validated procedure, full details can be found in [4]. The target values were calculated from the certified activity values assigned to each radionuclide, taking into account the successive dilution steps, the mass of spiking solutions and the amount of matrix being spiked. The target values together with the respective uncertainties are presented in Table 4. Seven samples were analysed using gamma spectrometry by five National Metrological Institutes (NMI) and two expert laboratories within the frame of the CCRI(II) S4 supplementary comparison organised in cooperation with the Committee Consultative on Ionization Radiation (CCRI) of BIPM. The IAEA target values were in good agreement with the consensus value derived from the measurement results of the NMIs. The consensus value of the NMIs was derived using a robust statistical approach Mixture Models Median (MM-median) described by David L. Duewer [5]. This approach

12

allows estimating the reference value in a robust way even when some of the results are not in agreement with the majority. Thus this approach is robust to outliers and in the same time accounts for the reported uncertainty of each result. The MM-median is a direct analogue of the median. It is the location which divides the MM-PDF into two sections of equal area. To estimate the dispersion of the analytical results the MM-median based Standard Deviation S(MM-median) was calculated from the span of the central 50% of the MM-PDF density [5]. Table 5 shows the consensus values as MM-median of NMIs results and the associated combined standard uncertainty. 2.3.2 Preparation of the natural grass sample 02 The sample 02 is a natural grass which was collected in Chernobyl area. The grass was dried, milled and sieved to collect the appropriate fraction at mesh size less than 0.25 mm, and then homogenised. The homogeneity was tested by analysing 10 samples at 10 replicates each at 5 g sample intake using 63X63 mm NaI(Tl) well type detector. Single way ANOVA [6] ISO Guide 35 was used to estimate the standard uncertainty originated from the between-bottles heterogeneity and was found to be 0.21% at sample intake 5 g. The 40K and 137Cs in the grass material were analysed using gamma spectrometry by a group of National Metrological Institutes (NMI) and two expert laboratories within the frame of the CCRI(II) S4 supplementary comparison organised in cooperation with the Committee Consultative on Ionization Radiation (CCRI) of BIPM. For deriving the target values a robust approach proposed by David L. Duewer [5] was used.

The target values of grass material with the respective uncertainties are presented in Table 4. 2.3.3 Preparation of the spiked water sample 03 The water sample was gravimetrically prepared in one batch. A portion of 300 kg of acidified demineralised water was spiked with a mixture of certified single radionuclide solutions traceable to a national standard of radioactivity. Then a pump with multiple outlets was used to homogenise the bulk water sample in a tank of 600 L. Seven samples were measured by a group of National Metrological Institutes (NMIs) by gamma spectrometry. The IAEA target values were in good agreement with the measurement results of the NMIs. The final target activity concentration for each radionuclide was calculated from the certified activity values assigned to each radionuclide, taking into account the successive dilution steps, the mass of spiking mixture and the amount of water being spiked as determined from weighing. The combined standard uncertainty includes two major components: uncertainty of the certified solution and weighing uncertainty. Figures 1, 2 and 3 show the PT materials sets. 2.3.4 Homogeneity testing The homogeneity test results provided experimental evidence that satisfactory level of within and between bottles homogeneity has been attained. Table 6 presents relative standard deviation of measurements results of ten bottles for water and soil at 60 g and for grass at 5 g sample intake. More information about the homogeneity testing could be found in [4].

2.4 Reference time The reference time for all activity concentrations is 1 June 2006.

3. Performance criteria

Several rating systems have been developed for determining a laboratory’s performance and the meaning of the results of the different scoring systems are not always comparable. Among various statistics, z-scores and u-scores are most often used. The drawback of z-scores is that the uncertainty of the participant’s measurement result is not taken into account for the evaluation of performance. In the case of u-scores, the evaluation includes uncertainties of the participant measurements and the standard uncertainty of the assigned value. Laboratories performing well in classical proficiency testing (z-scores) will not necessarily exhibit the same level of performance when their analytical uncertainties are considered in the evaluation. The proficiency testing scoring system applied by the Chemistry Unit in the Agency’s laboratories takes into consideration the trueness and the precision of the reported data and it includes in the evaluation both the combined standard uncertainty associated with the target value of proficiency testing samples and the combined standard uncertainty reported by the participating laboratories. This approach is aligned with the new requirements of the (ISO/IEC 17025:2005) [8] which require that laboratories have to express their measurement uncertainty. According to the newly adopted approach, the reported results are evaluated against the acceptance criteria for accuracy and precision and assigned the status “acceptable” or “not acceptable” accordingly. A result must pass both criteria to be assigned the final status of “acceptable”. The advantage of this approach is that it checks the credibility of uncertainty statement given by the participating laboratories, and results are no longer compared against fixed criteria but participants establish their individual

acceptance range on the basis of the uncertainties assigned to the values. Such an approach highlights not only methodological problems affecting the accuracy of the reported data but also identifies shortcomings in uncertainty estimation. In addition, three other statistical parameters namely: z-score, IAEA/Laboratory result ratio and relative bias are calculated as complementary information for the participating laboratories. 3.1 Relative bias The first stage in producing a score for a result ValueAnalyst (a single measurement of analyte concentration in a test material) is obtaining the estimate of the bias. To evaluate the bias of the reported results, the relative bias between the Analyst’s value and the IAEA value is calculated and expressed as a percentage:

P directly depends on the measurement uncertainty claimed by the participant. The Limit of Acceptable Precision (LAP) for each analyte respectively is defined for the respective proficiency test in advance, including any adjustment due to the concentration or activity level of the analytes concerned and the complexity of the analytical problem. Participants’ results are scored as “acceptable” for precision when P ≤ LAP. The LAP value used in the evaluation of all radionuclides is listed in Table 7. In the final evaluation, both scores for trueness and precision are combined. A result must obtain an “acceptable” score in both criteria to be assigned the final score “acceptable”. Obviously, if a score of “not acceptable” was obtained for both trueness and precision, the final score will also be “not acceptable”. In cases where either precision or trueness is “not acceptable”, a further check is applied. The reported result relative bias (R. Bias) is compared with the maximum acceptable bias (MAB). If R. Bias ≤ MAB, the final score will be “warning. “Warning” will reflect mainly two situations. The first situation will be a result with small measurement uncertainty; however its bias is still within MAB. The second situation will appear when result close to the assigned property value are reported, but the associated uncertainty is large. If R. Bias > MAB, the result will be “Not Acceptable”. The MAB value used in

the evaluation of all radionuclides is listed in Table 7. If the evaluation approach and/or acceptance criteria applied in this PT are not appropriate for the types of analyses and application performed in one of the participating laboratories, it is suggested to apply a self- scoring evaluation system which could fits specific requirements.

3.3 The z-score value The z-score is calculated from the laboratory results, the assigned value and a standard deviation in accordance with the following equation:

σ

IAEAAnalystScore

ValueValuez

−=

On the basis of the “fitness for purpose” principle, the target value for the standard deviation (σ) is:

0.10 x ValueIAEA The laboratory performance is evaluated as satisfactory if | z Score | ≤ 2; questionable for 2<| z Score |<3, and unsatisfactory for | z Score |≥3. 3.4 The u-score value The value of the utest was calculated according to the following equation [10]

22.. AnalystIAEA

AnalystIAEAtest

UncUnc

ValueValueu

+

−=

This value is compared with the critical value listed in the t-statistic tables to determine if the reported result differs significantly from the expected value at a

given level of probability. The advantage of the utest is that it takes into consideration the propagation of measurement uncertainties when defining the normalised error. This is especially useful when evaluating results, which uncertainty may overlap with the reference interval. It should be noted that the choice of the significance level is subjective. For this proficiency test we have set the limiting value for the u-test parameter to 2.58 for a level of probability at 99 % to determine if a result passes the test (u < 2.58). The MAB value used in the evaluation of all radionuclides is listed in Table 7.

4.1 General 677 results were reported to the IAEA in this PT from 38 laboratories in 29 countries. The participants’ data along with the statistical performance evaluation were compiled and presented. 30 laboratories reported within the agreed deadline for the rapid reporting measurement (three working days). The overall evaluation showed that 78 % of all reported results fulfilled the PT criteria. Table 8 shows the distribution of results scored as acceptable/warning/not acceptable for all evaluated nuclides. Appendix A shows a summary evaluation for each laboratory and an outline of the reported information in the PT questionnaire regarding the applied analytical technique. Performance evaluation tables sorted by analyte are reported in Appendix B, while the

performance evaluation tables sorted by laboratory code are presented in Appendix C. 4.2 Counting time, mass of the sample and moisture content The potential negative effect of rapid reporting on the quality of the results was examined. There was not any correlation or trend between the number of working days elapsed between the samples receipt and results reporting and the level of performance. It was found that the laboratories which reported their results after four or five working days did not show a better performance than those laboratories who respected the deadline; this is clearly demonstrated in Figure 4. The reported values for counting time, mass of the measured sample and moisture

content were plotted (Figures 5, 6 7) against the average of the obtained acceptable scores for each laboratory. It can be seen that the counting time varied from 3000 to 250000 second, the moisture content varied from 0.1 % to 4.5 % and from 1.4 % to 34 % in soil and grass respectively. Two laboratories reported high moisture content and it seems to be the reason for the lower performance of these laboratories. The sample mass in soil was between 3.5 g and 192 g and in grass was between 1.35 g and 34 g with no effect on the performance. 4.3 Uncertainty Most of the laboratory have followed the international guides for expression of uncertainties [11,12] and combined ‘all identified sources’ of uncertainty. Some participating laboratories gave detailed formulas and uncertainty data. On the other hand a few laboratories reported only uncertainty values produced by their software without knowing details what was included in this information. The reported values for the uncertainties in this PT were in most cases realistic; few laboratories reported too small uncertainties which could lead to a warning score.

4.4 Calibration The following calibration methods were reported: • Calibration using multi gamma

standard source; • Calibration using single gamma

standard sources; • Calibration using computational model; • Calibration using a spiked material; • Calibration using matrix certified

reference materials; 5. Conclusions This proficiency test exercise was successfully completed. Most participants were able to quantify all the nuclides in the three matrices with acceptable trueness and precision. The evaluation results show that there are no specific measurement problems for 40K0, 54Mn, 60C0, 65Zn, 134Cs, 137Cs, and 241Am. The most problematic nuclides were 109Cd and 210Pb in soil. In the case of 109Cd in soil only 45 % of all reported results respectively were in agreement with the IAEA target values. The main reason for the “Not Acceptable” scores in 109Cd results could be attributed to the overestimation of peak area due to unresolved interference around the region of the 88 keV in a densely populated X-ray region which is difficult to resolve. 210Pb which is a low energy nuclide (~45 keV) was also a problematic analyte, where results show a significant bias and incomparability among the laboratories. It is suggested that the major sources of the bias and incomparability in 210Pb results could be attributed to the inappropriate detector calibration in the low energy range and to the overestimation or underestimation of the self attenuation factor. In certain laboratories the efficiency

calibration was extrapolated, which led to large discrepancies. The need to produce new matrix reference materials for both 109Cd and 210Pb is obvious to assist in method validation and quality control of different matrices. It is recommended to repeat the same exercise with water and soil to check if the laboratories were able to introduce proper corrective actions to improve the results of 109Cd and 210Pb. The laboratories showed the lowest performance for the grass sample in which only 68 % of the laboratories gave an acceptable result for 137Cs. The laboratory performance for 137Cs was considerably better for soil and water (acceptable results 85 %). Considering the high activity concentration of 137Cs in the grass sample (11320 Bq kg-1) this low performance could be due only to an incorrect calibration for this type of matrix and/or to a wrong evaluation of the moisture content. This result should suggest to the laboratories to review their calibration procedures for this type of matrices and to improve their method for moisture content calculation. Generally speaking, this exercise provided the possibility to quantify the level of analytical performance of the ALMERA network members and it could be a step forwards the improvement of the network performance in the determination of gamma emitting radionuclides.
