| Terms for subject Environment (7347 entries) |
| radio programme (A performance or production transmitted in sound signals with electromagnetic waves) | 广播节目 | |
| radioactive contamination (Contamination of a substance, living organism or site caused by radioactive material) | 放射性污染 | |
| 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) | 放射性去污 | |
| radioactive dumping (Waste generated by the emission of particulate or electromagnetic radiation resulting from the decay of the nuclei of unstable elements) | 放射性废弃物 | |
| radioactive emission (The release of radioactive substances into the environment deriving from nuclear installations and from mining, purification and enrichment operations of radioactive elements) | 放射性发射 | |
| radioactive fallout (The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion) | 放射性尘降物 | |
| radioactive health data | 放射性安全保健数据 | |
| 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) | 放射性污染物 | |
| 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) | 放射性物质 | |
| 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) | 放射性指示剂 | |
| radioactive tracer | 同位素〔放射性〕示踪物 | |
| radioactive tracer | 放射显迹物 | |
| radioactive tracer technique | 放射性指示剂技术 | |
| radioactive waste (Any waste that emit radiation in excess of normal background level, including the toxic by-products of the nuclear energy industry) | 放射性废料 | |
| 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) | 放射性废料管理 | |
| radioactive-convective model | 辐射一对流模式 | |
| 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) | 放射性 | |
| radioelement (An element that is naturally radioactive) | 放射性元素 | |
| radionuclide (A nuclide that exhibits radioactivity) | 放射性核 | |
| 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) | 氡 |
