| Terms for subject Environment (6528 entries) |
| radioactive effluents | radioaktyvieji išmetalai | |
| radioactive emission (The release of radioactive substances into the environment deriving from nuclear installations and from mining, purification and enrichment operations of radioactive elements) | radioaktyviųjų medžiagų išmetimas | |
| radioactive fallout (The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion) | radioaktyviosios dulkės | |
| 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) | radioaktyvusis teršalas | |
| 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) | radioaktyvioji medžiaga | |
| 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) | radioaktyvusis žymeklis | |
| radioactive tracer technique | radioaktyviojo žymeklio technologija | |
| radioactive waste (Any waste that emit radiation in excess of normal background level, including the toxic by-products of the nuclear energy industry) | radioaktyvios atliekos | |
| 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) | radioaktyvių atliekų tvarkymas | |
| radioactive waste repository | radioaktyviųjų atliekų saugykla | |
| 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) | radioaktyvumas | |
| radioelement (An element that is naturally radioactive) | radioaktyvusis elementas | |
| radiological emergency | nepaprastoji radiologinė padėtis | |
| radiological emergency | radiacinė avarija | |
| radiological emergency | radiologinis pavojus | |
| radionuclide (A nuclide that exhibits radioactivity) | radionuklidas | |
| 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) | radonas | |
| rag (Discarded textile waste, either post-consumer waste or pre-consumer waste, such as manufacturing process scraps) | skudurai | |
| rail traffic (The movement and circulation of vehicles transporting goods and people on railroad systems) | geležinkelio eismas | |
| rail transport (Transportation of goods and persons by railway) | geležinkelio transportas |
