|
| radar |
radar (A system using beamed and reflected radiofrequency energy for detecting and locating objects, measuring distance or altitude, navigating, homing, bombing and other purposes) |
|
| radar meteorológico |
ground weather radar |
|
| radiação alfa |
alpha radiation (A stream of alpha particles which are ejected from many radioactive substances having a penetrating power of a few cm in air but can be stopped by a thin piece of paper) |
|
| radiação beta |
beta radiation (Name given to the ionizing radiation which is produced as a stream of high speed electrons emitted by certain types of radioactive substance when they decay. The intensity of radiation energy produced in human tissue by a beta particle is a hundred times less than that produced by an alpha radiation particle, but it travels slightly deeper into tissue) |
|
| radiação beta |
beta radiation |
|
| radiação cósmica |
cosmic radiation (Radiations consisting of atomic nuclei, especially protons, of very high energy that reach the earth from outer space. Some cosmic radiations are very energetic and are able to penetrate a mile or more into the Earth) |
|
| radiação de fundo |
background radiation (Radiation resulting from natural sources, as opposed to man-made sources, and to which people are exposed in everyday, normal life; for example from rocks and soil) |
|
| radiação de fundo natural |
natural background radiation |
|
| radiação de onda curta |
short-wave radiation |
|
| radiação fotossinteticamente ativa |
photosynthetic active radiation |
|
| radiação gama |
gamma radiation (Radiation of gamma rays) |
|
| radiação infravermelha |
infrared radiation (Electron magnetic radiation whose wavelengths lie in the range from 0.75 or 0.8 micrometer to 1000 micrometers) |
|
| radiação ionizante |
ionising radiation (Radiation that is capable of energizing atoms sufficiently to remove electrons from them. In this state atoms become more reactive, so that ionizing radiation increases chemical activity and in this way produces biological effects, including effects that involve alterations induced in DNA. X-rays and gamma-rays are the only electromagnetic waves that cause ionization in biological material) |
|
| radiação não-ionizante |
non-ionising radiation (Radiation that does not change the structure of atoms but does heat tissue and may cause harmful biological effects) |
|
| radiação não-ionizante |
non-ionising radiation |
|
| radiação policromática |
polychromatic radiation |
