WebJun 9, 2024 · The roentgen is a unit that measures nuclear radiation and is equal to the amount of radiation that produces \(2 \times 10^9\) ion pairs when it passes through \(1 \: \text{cm}^3\) of air. The primary concern is that ionizing radiation can do damage to living tissues. Radiation damage is measured in rems, which stands for roentgen equivalent … WebNUCLEAR FISSION Nuclear fission is the process of splitting the nucleus of a heavy atom (target nucleus) into two or more lighter atoms (fission products) when the heavy atom absorbs or is bombarded by a neutron. A few radionuclides can also spontaneously fission. Fission releases a large amount of energy along with two or more neutrons. inwall leaks https://andermoss.com
