Radioactivity is the term used to describe disintegration of atoms. The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation.
Jan 25, 2023 · 25 Jan 2023. Andrea Galindo, IAEA Office of Public Information and Communication. Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of radiation include the sun, microwave ovens in our kitchens and ...
Jul 17, 2024 · Radioactive sources include a range of different radionuclides and amounts of radioactive material. Sealed source: A radioactive source in which the radioactive material is (a) permanently sealed in a capsule or (b) closely bonded and in a solid form. The radioactive material is contained or bound within a capsule strong enough to prevent leaks ...
Jan 30, 2017 · Radiological environmental remediation. Environmental remediation aims to reduce radiation exposure from existing contamination of land, including groundwater or surface water. Its purpose is to return affected lands and water resources for safe public use. Nuclear regulators and operators of nuclear facilities are responsible for the ...
Jan 21, 2022 · In terms of overall volume, around 95% of existing radioactive waste has very low level (VLLW) or low-level (LLW) radioactivity, while about 4% is intermediate level waste (ILW) and less than 1% is high-level waste (HLW). Since the start of nuclear electricity production in 1954 to the end of 2016, some 390,000 tonnes of spent fuel were generated.
Jun 20, 2024 · The ionizing radiation symbol, featuring three curved blades emanating from a central point, has been used since 1946 to warn workers, scientists and the public of the presence of radioactive material. Since then, the distinctive trefoil has become an internationally recognized symbol. The symbol can be found wherever ionizing radiation or ...
May 31, 2024 · “These radioactive sources are imported and exported daily, and the maintenance of a high level of safety and security is essential as these radioactive sources may pose a risk due to accidental radiation exposure, inappropriate use or malicious intent,” said Lydie Evrard, Deputy Director General and Head of the IAEA Department of Nuclear ...
To support Member States in developing disposal programmes and solutions, the IAEA assists within the following areas: Addressing scientific, technical, institutional and socio-political issues through stakeholder involvement to support confidence building. Disposal is the final step in the management of radioactive waste.
radioactive waste, mainly focusing on waste generated . by electricity production. Radioactive waste is also generated through various other sources using nuclear technology, such as health care or research.

These radioactive elements in minerals and ores originally found in the environment are commonly known as NORM – naturally occurring radioactive material. Some NORM materials require radiation control and regulation. The activity concentrations of the radionuclides in rocks and soil found in the nature are generally low.
