Radioactive contamination, also called radiological pollution, 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 (from the International Atomic Energy Agency (IAEA) definition).
Contamination occurs if an object has a radioactive close radioactive When unstable atoms give off particles that can be harmful to humans. material introduced into it.
When the radioactive waste is dumped in the soil/subsoil or underground repositories, there is a possibility that the waste contaminates the soil and may affect the surrounding biota. This happens only if there is an accidental leakage in any of the canisters or capsuled wastes.
When radionuclides are released from a source, the receiving ecosystems will be affected by radioactive contamination. In radioecology, the assessment of environmental impact depends on the source and release scenarios, deposition and ecosystem system transport, including biological uptake and effects in exposed organisms. To identify the ...
Unstable nuclides undergo radioactive transformation, a process in which a neutron or proton converts into the other and a beta particle is emitted, or else an alpha particle is emitted. Each type of decay is typically accompanied by the emission of gamma rays.
Radioactive contamination is of a major concern worldwide due to its potential negative impact on living organisms. It is extremely important to understand the distribution and association of the radioactive elements to provide background information in the process of developing remediation strategies.
