(a) Describe the nuclear processes of alpha and beta decay, and describe what parameter is increasing in the nucleus as a result of these decays. [3] (b) Where a stationary neutron combines with a proton to form a deuteron, a gamma ray of energy 2.2233 MeV is emitted. The masses of the proton and the deuteron are 1.007276467 u and 2.013553212 u, respectively. Determine the mass of the neutron, stating any laws used and defining variables. [4] (c) Uranium ore mined today contains 0.72% of fissionable 235U, with the remainder being 238U. For use in a reactor, the ore needs to be refined to increase the fraction of 235U to 3%. How many years ago would natural uranium ore have been a practical reactor fuel, with a 235U/238U ratio of 3.0%? [3] Take 235U to have a half-life of 7.0 × 108 y and 238U to have a half-life of 4.5 × 109 y

One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron and a neutral particle called a neutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a beta particle. One nucleus that exhibits beta decay is the isotope of hydrogen 3H, called tritium, whose nucleus consists of...
