A one-gram sample of thorium 9% Th contains 2.64 x 102atoms and undergoes a decay with a half-life of 1.913 yr (1.677 x 10# h).Each disintegration releases an energy of 5.52 MeV (8.83 x 10-13 )). Assuming that all of the energy is used to heat a 3.67-kg sample of water, find the change in temperature of the sample that occurs in one hour. Number i Units Multiple-Concept Example 1 discusses the concepts that are relevant to this problem. A person undergoing radiation treatment for a cancerous growth receives an absorbed dose of 2.8 Gy. All the radiation is absorbed by the growth. If the growth has a specific heat capacity of 4400 J/(kg.Co), determine the rise in its temperature. Number Units A film badge worn by a radiologist indicates that she has received an absorbed dose of 3.0x 10" Gy. The mass of the radiologist is 65 kg. How much energy has she absorbed? Number i Units
