- Neon (10Ne) has three stable isotopes with consecutive mass numbers. Write the complete nuclear symbol (with neutron number) for each. (Enter your answer in the formX_{N}. Separate substances in a list with a comma.) chemPad О Help Greek -Using appropriate formula determine the decay constant (λ) for the parent-daughter isotope pair, 235U/207Pb. The half-life for this isotope pair is 713,000,000 years. Note that the decay constant (λ) of a radioactive nuclide is its probability of decay per unit time (units: s−1 or a−1).

Assume it had operated for 16 months before the tsunami and then was shut down for 20 days before the any radioactive material was released. a. How much fission product activity was present in the core at the time of the accidental release? b. Assuming 2 MeV per radioactive decay (1 MeV from a beta and 1 Mev from a gamma), and that all of the energy was deposited into the reactor core and coolant, how much heat (in MW) was being produced by the fission product activity on the 20th day?

The Q-value of a nuclear reaction is a measure of the kin ic energy of the mass that isb) Suppose a radioactive mineral sample undergoes decay. Originally, it contains Do number of non-radioactive daughter elements and No number of parent elements. Show that the expression for total daughter elements present now [i.e., D(t)now], will be a straight line (called isochron) with respect to the present number of parent elements. (mention the expression of the slope of the line).2310Ne is unstable. Complete the schematic energy diagram to the right by drawing in the protons and neutrons (with arrows representing spin directions) and predict how this nucleus will decay by specifying the final nucleus plus the two emitted particles. (This nucleus is small enough that electrostatic repulsion is not really significant.) Is the resulting nucleus stable?
- Think carefully about the fi ssion process. Does it seem peculiar that symmetric fission is not the most probable? Does the distribution shown in Figure seem reasonable? Explain.Describe the process of s nuclear fission?Radiocarbon dating assumes that the abundance of 14C in the environment has been constant. Suppose 14C was less abundant 10,000 years ago than it is today. Would this cause a lab using radiocarbon dating to overestimate or underestimate the age of a 10,000-yearold artifact? (In fact, the abundance of 14C in the environment does vary slightly with time. But the issue has been well studied, and the ages of artifacts are adjusted to compensate for this variation.)
