- Ionizing Radiation, Health Effects and Protective Measures
Radioactive pollution occurs when radioactive materials are deposited in the atmosphere or environment, especially when their presence is accidental and presents an environmental threat due to radioactive decay.
The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge or a nuclear reactor containment breach, the air, soil, people, plants, and animals in the vicinity will become contaminated by nuclear fuel and fission products.
Natural radioactive sources in the soil, water and air contribute to our exposure to ionizing radiation, as well as man-made sources resulting from mining and use of naturally radioactive materials in power generation, nuclear medicine, consumer products, military and industrial applications.
Therefore, the meaning of radiation pollution is that, while there are ubiquitous sources of radiation, it is mostly the high-energy radiation that causes radiation pollution, carrying serious health risks (such as cancer or death).
27 Ιουλ 2023 · People are exposed to natural sources of ionizing radiation, such as in soil, water, and vegetation, as well as in human-made sources, such as x-rays in medical devices. Ionizing radiation has many beneficial applications, including uses in medicine, industry, agriculture and research.
29 Ιουν 2016 · This publication does not set, or even recommend, radiation safety standards, rather, it provides information on basic science related to radiation (origin, quantities and units), on radiation effects (on humans and the environment) and on radiation sources (natural and artificial).
