NMTCB PREP EXAM (ACTUAL 2025/2026) QUESTIONS WITH VERIFIED CORRECT ANSWERS | GRADED A+ Common Reactor produced radionuclides? Mo-99/Tc-99m , I-131, I-125, Xe-133, Sr-89, Sm-153, P-32, Cr-51 Common Accelerator produced radionuclides? I-123, Th-201, Ga-67, In-111, All positron emitters Bremsstrahlung? *radiation that results from deceleration of the beta particles as they approach the nuclei Film Badge Imp. Points *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 *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 *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
