- In the 1986 disaster at the Chernobyl reactor in eastern Europe, about 1 8 of the 137 Cs present in the reactor was released. The isotope 137 Cs has a half-life of 30.07 y for β decay, with the emission of a total of 1.17 MeV of energy per decay. Of this, 0.51 MeV goes to the emitted electron; the remaining 0.66 MeV goes to a γ ray. The radioactive 137 Cs is absorbed by plants, which are eaten by livestock and humans. How many 137 Cs atoms would need to be present in each kilogram of body tissue if an equivalent dose for one week is 3.5 Sv? Assume that all of the energy from the decay is deposited in 1.0 kg of tissue and that the RBE of the electrons is 1.5.An unstable nucleus undergoes alpha decay with the release of 5.52 MeV of energy. The combined mass of the parent and daughter nuclei is 452 u. What was the parent nucleus? You can use Appendix D in Krane to identify the parent nucleus.Taking into account the recoil (kinetic energy) of the daughter nucleus, calculate the kinetic energy K(alpha) of the alpha particle in the following decay of a 238U nucleus at rest. 238U⟶234Th+alpha K(alpha) = ?

- Gold-197 has an atomic number of 79 and an atomic mass number of 197. The mass of a gold nucleus is 196.96657 u, whereas the mass of a proton is 1.00727u and the mass of a neutron is 1.00866u. What is the binding energy of a gold nucleus, expressed in MeV? (Use c=3E8 m/s for the speed of light and beware of units)A radium source contains 1.00 mg of 226Ra, which decays with a half-life of 1600 y to produce 222Rn, a noble gas. This radon isotope in turn decays by alpha emission with a half-life of 3.82 d. If this process continues for a time much longer than the half-life of 222Rn, the 222Rn decay rate reaches a limiting value that matches the rate at which 222Rn is being produced, which is approximately constant because of the relatively long half-life of 226Ra. For the source under this limiting condition, what are (a) the activity of 226Ra, (b) the activity of 222Rn, and (c) the total mass of 222Rn?A 200.0 - mCi sample of a radioactive isotope is purchased by a medical supply house.
