Radioactive impurity, also called radiological pollution, is the deposit of, or presence of radioactive substances on shells or within solids, liquids, or feasts (including the mortal body), where their presence is unintended or undesirable (from the International Atomic Energy Agency. Similar impurity presents a hazard because the radioactive decay of the pollutants, produces ionizing radiation (videlicet nascence, beta, gamma shafts and free neutrons). The degree of hazard is determined by the attention of the pollutants, the energy of the radiation being emitted, the type of radiation,and the propinquity of the impurity to organs of the body. It’s important to be clear that the impurity gives rise to the radiation hazard, and the terms” radiation” and” impurity” aren’t exchangeable.
