All Rights Reserved. The first thing you think of as radiation is probably X-rays, but what cooks your food in the microwave oven is also radiation. This is, usually, not the case. Nuclear Stability is a concept that helps to identify the stability of an isotope. Nuclear weapon - Nuclear weapon - Residual radiation and fallout: Residual radiation is defined as radiation emitted more than one minute after the detonation. n. 1. Ionizing radiation which can damage living tissue is emitted as the unstable atoms (radionuclides) change ('decay') spontaneously to become different kinds of atoms. They contain chemicals and burn brightly or attractively, often with a loud noise , when you light them. Which, despite the negatives, saw a healthy increase in good-neighbourliness and kindness as demonstrated, for instance, by caremongering. Over a very long period of time, radioactive waste will eventually lose its radioactive qualities and will no longer be dangerous material. Radiation definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. Light, heat, and the microwaves and radio waves used for wireless communications are all forms of radiation. It is present in the environment because naturally occurring Very fast moving. What is the definition of nuclear radiation? Both alpha and beta particles have an electric charge and mass, and thus are quite likely to interact with other atoms in their path. Nuclear radiation arises from hundreds of different kinds of unstable atoms. As the level of radiation rises, radiation can cause hair loss, loss of white blood cells (making casualties of radiation even more susceptible to infections), and can result in death.
