Part A Gamma rays may be used to kill pathogens in ground beef. One irradiation facility uses a Co source that has an activity of 1.0 x 106 Ci. Co undergoes beta decay and then gives off two gamma rays, at 1.17 and 1.33 Me V; typically 30% of this gamma-ray How many kilograms of meat per hour can be processed in this facility? energy is absorbed by the meat.

He ingests 3.7 MBq of 198 Au, which decays with a 2.7 day half-life by emitting a 1.4 MeV beta particle. Medical tests show that 60% of this isotope is absorbed and retained by the liver.
