distance of one meter have been measured. These gamma constants can be used to determine 1) the expected exposure rate at a given distance (using the inverse square law) for a known quantity of a radionuclide, or 2) the activity of a radionuclide from a measured exposure rate. Gamma constants ( ) for selected radionuclides can be found on page 43.
