Calculate the effective radiation dosage (in Sieverts) for a 81-kg person who is exposed to 1.9 x 109 particles of alpha radiation. Assume that 79% of the radiation is absorbed, each alpha particle has an energy of 6.2 x 10-13 J, and that the RBE of the alpha particles is 15. Note that RBE is sometimes called the quality factor, abbreviated as Q.
Four radiation doses are as follows: Dose A is 0.10 Gy with an RBE of 1, dose B is 0.20 Gy with an RBE of 1, dose C is 0.10 Gy with an RBE of 2, and dose D is 0.20 Gy with an RBE of 2. a. Rank in order, from largest to smallest, the amount of energy delivered by these four doses. b. Rank in order, from largest to smallest, the biological damage caused by these four doses.
Calculate the radiation dosage (in grays) for an 81-kg person that is exposed for 9.0 seconds to a 3.0 Ci source of beta radiation. Assume that 100% of the radiation is absorbed and each beta particle has an energy of 1.4 ×× 10-13 J.

- It has become popular for some people to have yearly whole-body scans (CT scans, formerly called CAT scans) using x rays, just to see if they detect anything suspicious. A number of medical people have recently questioned the advisability of such scans, due in part to the radiation they impart. Typically, one such scan gives a dose of 12 mSv, applied to the whole body. By contrast, a chest x ray typically administers 0.20 mSv to only 5.0 kg of tissue. How many chest x rays would deliver the same total amount of energy to the body of a 75 kg person as one whole-body scan?arrow_forwardAn organic sample of mass 4.00 kg absorbs 2.00 mJ via slow neutron radiation (RBE=5).What is the dose equivalent (mSv)?arrow_forwardA gamma scan showing the active volume of a patient’s lungs can be created by having a patient breathe the radioactive isotope 133Xe, which undergoesbeta-minus decay with a subsequent gamma emission from the daughter nucleus.
