A worker group has a total exposure limit of 5 mR. The group must perform work in a
radiation area at a 2 meter distance from a 5 curie point source emitting a single 0.662
MeV gamma ray with an abundance of 85%. What is the stay time of the workers? -
ANS-0.8 minutes

The process by which a radioactive nuclide has a distinctive decay rate which is not
influenced by any physical process including biological functions is called what? -
ANS-Radioactive decay

radionuclide by the volume of air breathed by an average worker during a working year
and has a unit of activity per volume? - ANS-Derived air concentration

Which formula is used to determine the gamma radiation field intensity in R/hr at one
meter from a radioactive point source? - ANS-0.5 CEN
