Write the nuclear equation for the fusion of H-3 with H-1 to form He-4.

A breeder nuclear reactor is a reactor in which U-238 (which does not undergo fission) is converted into Pu-239 (which does undergo fission). The process involves bombardment of U-238 by neutrons to form U-239, which undergoes two sequential beta decays. Write nuclear equations to represent this process.

Write a series of nuclear equations in which Al-27 reacts with a neutron and the product undergoes an alpha decay followed by a beta decay.

The fission of U-235 produces 3.2 * 10-11 J/atom. How much energy does it produce per mole of U-235? Per kilogram of U-235?

The fusion of deuterium and tritium produces 2.8 * 10-12 J for every atom of deuterium and atom of tritium. How much energy is produced per mole of deuterium and mole of tritium? Exercises | 637

If a person living in a high-radon area is exposed to 0.400 rem of radiation from radon per year, and his total exposure is 0.585 rem, what percentage of his total exposure is due to radon?

An X-ray technician is exposed to 0.020 rem of radiation at work. If her total exposure is the national average (0.36 rem), what fraction of her exposure is due to on-the-job exposure?

Radon-220 undergoes alpha decay with a half-life of \(55.6 \mathrm{~s}\). If there are 16,000 atoms present initially, make a table showing how many atoms are present at \(0 \mathrm{~s}, 55.6 \mathrm{~s}\), 111.2 s, 166.8 s, 222.4 s, and 278.0 s. (Note that the times selected for observation are multiples of the half-life.) Make a graph of number of atoms present on the y-axis and total time on the x-axis.
