radioaktiivne aine |
radioactive substance (Any substance that contains one or more radionuclides of which the activity or the concentration cannot be disregarded as far as radiation protection is concerned) |
|
radioaktiivne element |
radioelement (An element that is naturally radioactive) |
|
radioaktiivne emissioon |
radioactive emission (The release of radioactive substances into the environment deriving from nuclear installations and from mining, purification and enrichment operations of radioactive elements) |
|
radioaktiivne heide |
radioactive effluent |
|
radioaktiivne isotoop |
radionuclide (A nuclide that exhibits radioactivity) |
|
radioaktiivne saasteaine |
radioactive pollutant (A substance undergoing spontaneous decay or disintegration of atomic nuclei and giving off radiant energy in the form of particles or waves, often associated with an explosion of a nuclear weapon or an accidental release from a nuclear power plant, holding facility or transporting container) |
|
radioaktiivne saastumine |
radioactive contamination (Contamination of a substance, living organism or site caused by radioactive material) |
|
radioaktiivne sade |
radioactive fallout (The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion) |
|
radioaktiivse saaste ärastus |
radioactive decontamination (The removal of radioactive contamination which is deposited on surfaces or may have spread throughout a work area. Personnel decontamination is also included. Decontamination methods follow two broad avenues of attack, mechanical and chemical) |
|
radioaktiivsed jäätmed |
radioactive waste (Any waste that emit radiation in excess of normal background level, including the toxic by-products of the nuclear energy industry) |
|
radioaktiivsete jäätmete käitlus |
radioactive waste management (The total supervision of the production, handling, processing, storage and transport of materials that contain radioactive nuclides and for which use, reuse or recovery are impractical) |
|
radioaktiivsete jäätmete panila |
radioactive dumping (Waste generated by the emission of particulate or electromagnetic radiation resulting from the decay of the nuclei of unstable elements) |
|
radioaktiivsus |
radioactivity (The property possessed by some atomic nuclei of disintegrating spontaneously, with loss of energy through emission of a charged particle and/or gamma radiation) |
|
radioelement |
radioelement (An element that is naturally radioactive) |
|
radioisotoop |
radionuclide (A nuclide that exhibits radioactivity) |
|
radiomärgend |
radioactive tracer (A radioactive isotope which, when injected into a biological or physical system, can be traced by radiation detection devices, permitting determination of the distribution or location of the substance to which it is attached) |
|
radiomärgenditehnika |
radioactive tracer technique |
|
radionukliid |
radionuclide (A nuclide that exhibits radioactivity) |
|
radoon |
radon (A radioactive gaseous element emitted naturally from rocks and minerals where radioactive elements are present. It is released in non-coal mines, e.g. tin, iron, fluorspar, uranium. Radon is an alpha particle emitter as are its decay products and has been indicted as a cause of excessive occurrence of lung cancer in uranium miners. Concern has been expressed at radon levels in some housing usually adjacent to granite rocks or old tin mining regions) |
|
rafineerimine |
refining (The processing of raw material to remove impurities) |
