using 50 curies of ir92 what would be the dose rate at 75 ft from the source
Consider a 15,000-Ci 60Co source which gives off gamma rays of 1.17 MeV and 1.33 MeV from each decay. Assume that the dose rate at a distance R (cm) from a source of strength C (Curies) emitting gamma energy E (MeV) for each disintegration is given by: Calculate the dose rate at 1 m from the source and the time to receive the 75 rad. (Ans. t=21 seconds)

A radioactive source emits 2.4-MeV neutrons at the rate of 7773 neutrons per second. The number of atoms in the source is 2.38x10^9. What is the activity of the source, in nano-curies (nCi)?
5) An individual is 50 cm away from a radiation source and is exposed to 1000 Roentgens of radiation (not good). Assuming exposure to 111.1 Roentgens is the maximum dose that an individual may be exposed to without major adverse effects, what is the minimum safe distance from the radiation source? (4
