Common Reactor produced radionuclides? - ANSWER-Mo-99/Tc-99m , I-131, I-125, Xe-133, Sr-89, Sm-153, P-32, Cr-51 Common Accelerator produced radionuclides? - ANSWER-I-123, Th-201, Ga-67, In-111, All positron emitters Bremsstrahlung? - ANSWER-*radiation that results from deceleration of the beta particles as they approach the nuclei Film Badge Imp. Points - ANSWER-*made of 3to4 filters (Pb, Cu, Al, plastic) *should be worn between waist and shoulder *processed monthly *adversely affected by heat and moisture *the amount of darkening on the film is proportional to amount of radiation absorbed *effective measuring 10 mrem to several hundred rem TLD Badge Imp. Points - ANSWER-*thermoluminescent dosimeter *uses LiF crystal that emits a quantity of light proportional to the amount of radiation absorbed by crystal *this light is released during high hearing called annealing *can distinguish beta from photon/neutron radiation *can only be analyzed once *are used ring badges (forefinger) OSLD Badge Imp. Points - ANSWER-*optically stimulated luminescent dosimeter *uses thin slice of aluminum oxide to detect radiation *resistant to heat, moisture and aging *can be used to monitor more than once, up to 3 months *can be analyzed multiple times Caution: Radiation Area (sign) - ANSWER-*where individual can receive more than 5 mrem (0.05 mSv) in 1 hour at 30 cm *seen in entrances to nuc med labs Caution: Radioactive Materials (sign) - ANSWER-*where radioactive materials are used or stored *usually in entrances of work areas and NM labs *indicates potential presence of radiation sources and/or contamination Caution: High Radiation Area (sign) - ANSWER-*individual can receive more than 100 mrem (1 mSv) in 1 hour at 30 cm from radiation source *com
