Health Fhysica unit---

Arrangements have been finalized for provision of Health Physics coverage ofan operation to be conducted at the Los Angeles Division over a one month period .Atomics International (Al) will provide the necessary personnel and equipment .

A complete survey of an radiation-producing devices at Building 004 has beencompleted. One device was found to produce excessive radiation levels, andproject was informed to exercise especial caution when using this device .Additional measurements es!ll be made around this device in order to provideproject with the information necessary to correct the condition .

The North American Aviation, Inc . (WAA) industrial hygienists met at Autoneticsto discuss beryllium sampling and analytical techniques . Development of aCorporate Standard for sampling was started . Spiked beryllium samples are beingprepared by Autonetics and will be sent to each Division for checking theiranalytical procedures .

Enrico Conti, Industrial Hygienist, Atonic Tner Commission - Chicago OperationsOffice (AEC-COO), called for further information regarding the composition ofthree weed killers used at Al. This info tion was requested from him by theFederal Commission on Pest Control. They advised hr. Conti • that one product,Hytrar X, should not be used .. Since no reasons were given, we requested furtherinformation before notifying our pent control contractor not to use it .

All cartridge-type respirators in Building 00ls, 005, and the k4tixntenenrce buildingwere collected, and issuance of this equipment is now under Health and Safetycontrol, All of Canoga now has a formalized respirator program and plans areunderway to complete the program at Santa Susanna . .thin the next three weeks .

Review and comment was completed on the standard examination proposed by GeneralOffices (CO) for license to operate en in-plant motor vehicle at 14AA divisions .It was felt desirable to lengthen and make the e .ination more comprehensive,so additional test questions were prepared for consideration by CO,.

Review was completed of a proposed corporate wade training course for constructioncoordinators. The course material is appropriate . Our comments included recommen-dation of certain additions to cover requiremenrts for work in areas in whichpotential radiation and contamination hazards exist .

A Saturn 11 firing occurred Jar l6, 1965 at 2,2 :30 P.M. for thirty seconds.Soused levels were not measured by Al duo to lack of customary ten minutenotification . Roeketdyne field observers report the sound levels were thesame as the 212 decibel (db) recorded on previous tests .

Saturn II fired for two minute and fifteen seconds at 0900, d'ulv 20, 1965.The firing was about fifteen minutes ahead of the announced schedule, sosound pressure readings were not done blr ouar staff . Rocketdyne Health and.Safety personnel made readings at their explosive forming pit which isapproximately ?00 yards closer to the COCA complex than our observation areas

5ystseatio Analysis Procedure - A method has been developed to facilitate asystematic approach to the various types of analyses performed by the RadiationEngineer-.°sng Unit . heoo analyses may be broadly categorized as follows :

A. Radiation Safety Analysis

Analysis of proposed task to (1) determine safetycriteria, (2) identify potential hazards , (3) specifyengineering and procedural safeguards to satisfycriteria.

B . Radiation Safety Standard Analysis

Analysis of radiation safety requirements to establishgeneral lieu. design and operational standards andprocedures .

C. Plant Safety Analysis

Analysis of proposed fa i iti,.es or facility modificationsto (1) determine safety criteria, (2) identify potentialhazards, (3) specify design requirements and safeguardsto satisfy safety criteria. .

D . System Safety Analysis

Analysis of proposed systems or existing system applicationsor modifications to (1) determine safety criteria, (2)identify Potential hazards, (3) specify design requirementsand engineering and procedural safegtuds to satisfy safetycriteria.

The method involves the preparation of a standardized Radiation EnginoorthgAnalysis, rather than an IL, to report and document the work . Each documentbegins with a description of the task and statements as to the purpose andscope of the analysti ee The specific radiation safety criteria for the taskare listed, followed by a description of required safeguards (or designrequirements) s

Each document is concluded by an analysis which demonstrates that thesafeguards (or design requirements) are adequate to meet the criteria . Thepurpose, scope, and criteria are written by the supervisor, effecting awritten assignment to the ongineer° who then performs the analysis toidentify the necessary safeguards (or design requirements) . This methodhas been adopted (1) to systematize the unit's approach to analysis and(2) to provide a basic analytical document for material that is latersummarized in man4als and reports .

Plutonium Materials Dovelopmont Facility (PMP) - A system safety analysiswas completed for the Facility Annunicator and Control. Panels to be locatedin the Administrative Area and Glove Box Room at the P`f5)1 . These Danels areintended to provide audible and visual alarz s for abnon al conditions at thefacility and to provide a. visual. indication that the necessary action is bedtaken.

Past Breeder Reactor (FBR ) Prograw -- A radiation safety anairsis was completedin support of propos ed work to be performed with clad plutonium bearing f'`elrodso The work includes X-ray procedures, eoditm bonding , and eddy currenttesting. The safety criteria established for the work basically state thatphysical Protection. and oontaona tion control features provided by the st andardencapsulation of plutonium sources PuRe ) must be effectively presentat a l times
