- A person faces the possibility of receiving the following absorbed doses of radiation: 30 rad of X rays (RBE = 1), 5 rad of protons (RBE = 32), and 7 rad of alpha particles (RBE = 20). Which radiation will produce the least biological damage? a) the X-rays b) the alpha particles c) the protons d) They will produce the same damage.You suspect that a patient’s arm is broken. What type of radiation might help you find out?A tumor is exposed to a beam of protons containing 2.6 × 1010 protons. If 25% of the beam energy is absorbed in a tumor of mass 1.25 kg, what is the dose equivalent in the tumor? Each proton has an energy of 52 MeV, and the RBE of this type of radiation is 32. a) 0.043 Sv b) 1.38 Sv c) 4.3 Sv d) 13.8 Sv e) 37 Sv
- Explain why for beta ray shielding, usually two shields rather than one single shield are used.Suppose that you want to find out how much gasoline is in an underground storage tank. You pour in 1 gallon of gasoline that contains some radioactive material with a long half-life that gives off 5000 counts per minute. The next day, you remove a gallon from the underground tank and measure its radioactivity to be 10 counts per minute. How much gasoline is in the tank?What is the proper minimum required radiation protection for gamma radiation?
- The radioisotope Tc is an isotope that sometimes given to patients because it emits gamma rays and has a relatively short half-life of 6.05 h. Because emits gamma rays, 43 can be used as a tracer when performing imaging on a specific part of the human body. (a) Find the decay constant of "Tc (in h-l). h-1 (b) Find the number of Tc nuclei needed to provide an activity of 2.61 pCi. nucleiYou have been hired by a company interested in establishing a radioisotope production plant in your city where there is growing resistance against the plant because of ignorance in the uses of radiation. Convince the peopleat a town hall meeting by listing three different applications (uses) of radioisotopes/radiation.66/28Ni (mass = 65.929 1 u) undergoes beta decay to 56/29 (mass = 65.928 9 u). (a) Write the complete decay formula for this process. (b) Find the maximum kinetic energy of the emerging electrons.
