(a) Determine the total amount of energy released in the complete decay of 1 mg of tritium.
(b) According to the law of radioactive decay, how much time would this release of energy span?
(c) In a practical sense, how much time will it span?
Ten milligrams of pure polonium-210 is placed in 500 g of water.If no heat is allowed to escape to the surroundings, how much will the temperature rise in 1 hour?
Thorium 232 is rather abundant on Earth and is now coming into use as a breeder fuel. It behaves almost exactly like uranium- 238, merely shifted by even numbers of protons and neutrons, which means that it is not the actual fission fuel. What isotope is?
Certain nuclei with half-lives between days and a few years are found in nature in small abundances that do not change at all over many, many years. How is this possible? (Hint: Natural uranium and thorium have very long half lives.)
why does fission of heavy nuclei tend to produce free neutrons?
