Question

A 73.0 kg person experiences a whole-body exposure to alpha radiation with energy of 1.50 MeVMeV. A total of 5.40×1012 alpha particles is absorbed. Use the Table of Relative biological effectiveness (RBE) for several types of radiation.

A) What is the absorbed dose in rad?
Express your answer in rads.
 
B) What is the equivalent dose in rem?
Express your answer in rem.
 
C) If the source is 0.0100 g of 226Ra (half-life 1600 years) somewhere in the body, what is the activity of the source?
Express your answer in decays per second.
 
D) If all the alpha particles produced are absorbed, what time is required for this dose to be delivered?
Express your answer with the appropriate units.
