| radioattività |
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) |

| Radioattività dell'aerosol |
aerosol activity |

| radioelemento |
radioelement (An element that is naturally radioactive) |
|
| radiometro passivo a microonde |
passive microwave radiometer |
|
| radionuclide |
radionuclide (A nuclide that exhibits radioactivity) |
|
| radon |
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) |
