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...

1. Carbon monoxide poisoning can happen because carbon monoxide has a higher affinity for hemoglobin than oxygen does. This can be seen by comparing the equilibrium constants for the two reactions Hb(a)+02()Hb02(aq) Hb(a)C(e) HbCO(aq) K 1.9x1012 K 1.1x1014 where Hb is hemoglobin. The actual reactions are more complicated since each hemoglobin can accept up to four oxygen molecules, but we will simplify it for this problem A concentration of about 12,500 parts per million of CO is considered highly lethal....
