The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. T…

Artificial Radioactivity

The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.

Textbook Question

Chapter 32, Problem 48PE

The naturally occurring radioactive isotope ²³²Th does not make good fission fuel, because it has an even number of neurons; however, it can be bred into a suitable fuel (much as ²³⁸U is bred into ²³⁹P).

(a) What are Z and N for ²³²Th?

(b) Write the reaction equation for neutron captured by ²³²Th and identify the nuclide ^AX produced in n + 232 Th → A X + γ .

(c) The product nucleus β⁻ decays, as does its daughter. Write me decay equations for each, and identify the final nucleus.

(d) Conform that the final nucleus has an odd number of neutrons, making it a better fission fuel.

(e) Look up the half−life of the final nucleus to see if it lives long enough to be a useful fuel.
