A beam of 5.0 MeV alpha particles (q-2e) has a cross-sectional area of 1.50 cm2. It is incident on flesh (p-950
kg/m³) and penetrates to a depth of 0.70 mm. a) What dose in Gy does the beam provide to the flesh in a time of
3.0 s? b) What effective dose does it provide? Assume the beam to carry a current of 2.50 x 109 A and to have QF
- 14.
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?
An x-ray technician works 5 days per week, 50 weeks per year. (Assume that the technician takes an average of six x-rays per day and receives a dose of 4.1 rem/yr as a result.)
(a) Estimate the dose in rem per x-ray taken. (b) How does this result compare with the amount of low-level background radiation the technician is exposed to? Assume that low-level radiation from natural sources, such as cosmic rays and radioactive rocks and soil, delivers a dose of approximately 0.13 rem/year per person. __________times the normal background level
