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...

If naturally occurring 40K is responsible for a dose equivalent of 0.16 mSv/y of background radiation, calculate the mass of 40K that must be inside the 59 kg body of a woman to produce this dose. Assume that each 40K decay emits a 1.30 MeV β, and that 40% of this energy is absorbed inside the body. The half life of 40K is 1.25 × 109 years.

How do you calculate BMI for a L bka? In the problem we have a patient with a Left Below knee amputation and are suppose to calculate BMI for the patient: age:38 height: 69 inches weight: 210 pounds. I calculated BMI and got 31.0081916 but I don't know how to factor in the L bka. Please help thank you

Empirical results have revealed that for every unit of radiation
dose (1 rad) there are 5 ✕ 1011 inactivating events per
cubic centimetre treated.

inactivating events per cubic centimetre would this dose
produce?
inactivating events per cubic centimetre
