| Terms for subject Environment (5179 entries) |
| radiation sickness (The complex of symptoms characterizing the disease known as radiation injury, resulting from excessive exposure of the whole body (or large part) to ionizing radiation. The earliest of these symptoms are nausea, fatigue, vomiting, and diarrhea, which may be followed by loss of hair (epilation), hemorrhage, inflammation of the mouth and throat, and general loss of energy) | malalties d'origen radiactiu | |
| radio (The process, equipment or programming involved in transmitting and receiving sound signals by electromagnetic waves) | radi | |
| radio programme (A performance or production transmitted in sound signals with electromagnetic waves) | programa de ràdio | |
| radioactive contamination (Contamination of a substance, living organism or site caused by radioactive material) | contaminacío radiactiva | |
| 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) | descontaminació radiactiva | |
| radioactive dumping (Waste generated by the emission of particulate or electromagnetic radiation resulting from the decay of the nuclei of unstable elements) | abocament radiactiu | |
| radioactive emission (The release of radioactive substances into the environment deriving from nuclear installations and from mining, purification and enrichment operations of radioactive elements) | emissió radiactiva | |
| radioactive fallout (The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion) | polsim radiactiu | |
| 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) | contaminant radiactiu | |
| 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) | substància radiactiva | |
| 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) | traçador radiactiu | |
| radioactive tracer technique | tècnica de traç radiactiu | |
| radioactive waste (Any waste that emit radiation in excess of normal background level, including the toxic by-products of the nuclear energy industry) | residu radiactiu | |
| 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) | gestió de residus radioactius | |
| 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) | radioactivitat | |
| radioelement (An element that is naturally radioactive) | cos simple radioactiu | |
| radionuclide (A nuclide that exhibits radioactivity) | radionúclid | |
| 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) | radó | |
| rag (Discarded textile waste, either post-consumer waste or pre-consumer waste, such as manufacturing process scraps) | drap | |
| rail traffic (The movement and circulation of vehicles transporting goods and people on railroad systems) | trànsit ferroviari |
