Slide 11 Four Primary Types of Ionizing Radiation Radioactivity is the natural property of certain nuclides to spontaneously emit energy in the form of ionizing radiation in an attempt to become more stable. Alpha Large mass, rather high energy Beta Small mass, energy varies Beta Small mass, energy varies Gamma (X-ray) no mass, energy varies Gamma (X-ray) no mass, energy varies n Neutron mass proton, energy varies n Neutron mass proton, energy varies Slide 12 The Language of Radiation Radiation Units Millirem (mrem) Millicurie (mCi) Counts per minute (cpm) Microcurie (uCi) Slide 13 ALARA As Low As Reasonably Achievable External dose Time Distance Shielding Plastic Lead Dry runs Internal dose Inhalation Ingestion Absorption Injection Slide 14 Women of Childbearing Age Contact: Priya Rayadurgam x 2-2494 Is confidential Declaration of Pregnancy Form More Information Regulatory Guide 8.13 Slide 15 Posting/Labeling Post All Radioactive Materials Use Areas. Label refrigerators and Freezers. Label containers, tubes, racks, pipettes, anything coming in contact with radioactive material. Clean Areas Slide 16 Audits/Renewals Intended to assist uFrequency of audits High use lab twice a year Low use lab once per year uRenewal Annually includes required radiation safety refresher training. Slide 17 Ordering/Receipt Use lab protocol for purchase orders Radioactive material will be delivered to your location EH&S Services Lab Closed weekends and holidays (Formally known as the Isotope Lab) UCtr 301B Call 4-6418 or 4-0902 You may pick up or Services Lab will deliver. Slide 18 EH&S Services Lab Slide 19 Isotope Inventory Card Each stock vial of radioactive material received will have an inventory number and barcode assigned to it. The user should keep a record in mCis of aliquots taken from the stock vial. Slide 20 5 Key concepts you must take away from this seminar and will be held accountable for while you remain an active user listed on an RUA. Know how to access your RSM Know where your RUA is located Complete Isotope Inventory Card Slide 21 Inventory Control Report in units of mCi Quarterly updates Mailed 1 st week of months: January, April, July, and October Must sign and return even if you have no inventory Mail Code: 0035, FAX: 858-822-8824 Sealed sources Leak testing- Rad Safety will perform every 6 months Slide 22 Decay calculated by Services Lab Last reported amount by lab All Users listed on the RUA must know where all Radioactive Inventory is at all times. Security and Control is the Goal. Slide 23 5 Key concepts you must take away from this seminar and will be held accountable for while you remain an active user listed on an RUA. Know how to access your RSM Know where your RUA is located Complete Isotope Inventory Card Know where your inventory is at all times Slide 24 Surveys Wipes- Required in labs that have H-3 in inventory and/or area with high background Survey Meter Check meter for proper functioning Use appropriate probe Frequency for documented surveys High use = Weekly Low use = Monthly >10mCi/exp = Daily (or after each use) The more you survey the less chance contamination will be missed. Pancake Probe Scintillation Probe Slide 25 How to Use a Survey Meter The instrument has limitations P-32 = 15%, S-35 = 5%, I-125 = 10% You must use the meter correctly to obtain an accurate measurement. Need to know the Characteristics of the Isotope you are measuring in order to choose the correct instrument to do your survey. Slide 26 Radioactive Waste Store behind appropriate shielding Collect in appropriate containers Collect rinses from contaminated lab-ware Labeling At start of accumulation label with: Isotope & Caution radioactive materials International Trefoil symbol RAD waste tag must be complete at time of pick up Radioactive Materials/Waste cannot go down the drain or in the trash Keep outside surface of waste containers free of contamination Keep waste areas clear of debris Avoid accumulating large amounts of radioactive waste on site Slide 27 Radioactive Waste Tag Waste Generator Bar Code Label Lab Contact Name/Phone Building/Room Isotope and Activity in mCi Description of other constituents (Chem. Bio.) List method of disinfection if applicable. Deactivated with 10% bleach Slide 28 Radioactive Waste Dos and Donts Isotope Separate waste stream for each: S-35, P-32, I-125, P-33, H-3/C14 Liquid Solids out of the liquid waste, (Carboy) Secondary containment Solids Liquids out of the solid waste Gels - Double bag using clear plastic bags. Sharps - Puncture proof container Stock Vials - Double bag Animals - Wrap in bench-cote, double bag, store in freezer LSC Vials Cardboard crate or double bag No Radioactive trash in regular trashcans. No Radioactive liquid waste down the drain. Minimize non-radioactive materials in radioactive trash. Only authorized users on RUA can prepare waste for pick-up.

Slide 34 Safety Video II Slide 35 Spills Stop Moving Call for HELP and a Survey Meter Warn others To stay out of area Isolate the area Isolate the spill Locate using SM Minimize exposure Decontaminate Clean spill immediately. If require assistance call 534-HELP (534-4357) Slide 36 5 Key concepts you must take away from this seminar and will be held accountable for while you remain an active user listed on an RUA. Know how to access your RSM Know where your RUA is located Complete Isotope Inventory Card Know where your inventory is at all times First thing to do if you spill STOP Moving Slide 37 Spills continued Decontaminate personnel first! Contaminated clothing should be removed. Use warm water, be gentle, do not break skin, no scrub brush, do consult with EH&S Radiation Safety Using two people to clean up a spill is preferable. Spill needs to be documented according to UCSD requirements.
