A worker in a radiation lab recieves a whole-body radiation dose of 21 mrad. Her mass is 75 kg. The radiation delivered by alpha particles for which the RBE is 12. 1) What was the total energy absorbed by her body? Eabsorbed = 2) What was her equivalent absorbed dose in mREM? Doseeq= 3) As a normal employee, your allowable equivalent dose for an entire year is around 500 mREM. What percentage of of her annual dose did this employee...

Background (Part 1): We are continuously exposed to ionizing radiation from natural and artificial sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground and cosmic radiation to man-made sources such as medical x-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 620 millirem. In this activity, you will use the interactive online dose calculator to estimate...
