Radioactive contamination

Radioactive contamination, also known as radiological contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases (including the human body), where their presence is unintended or undesirable.

Causes

Radioactive contamination can occur as a result of certain activities such as nuclear power generation, nuclear weapons production and detonation, coal burning, and nuclear medicine. It can also occur naturally due to the presence of radon gas.

Effects

The effects of radioactive contamination can be harmful to both the environment and human health. Exposure to radioactive substances can cause radiation sickness, cancer, and genetic damage. It can also harm wildlife and damage ecosystems.

Prevention and Decontamination

Prevention of radioactive contamination involves a variety of measures such as the use of protective clothing, the use of barriers to prevent the spread of contamination, and the use of radiation detection equipment. Decontamination can be achieved through a variety of methods including the removal of contaminated materials, the use of chemical treatments, and the use of physical processes such as washing or scrubbing.
