Terms for subject Environment containing radiation | all forms | exact matches only
EnglishHungarian
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 paperalfa-sugárzás
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 soilháttérsugárzás
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 tissuebéta-sugárzás
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 Earthkozmikus sugárzás
gamma radiation Radiation of gamma raysgamma-sugárzás
infrared radiation Electron magnetic radiation whose wavelengths lie in the range from 0.75 or 0.8 micrometer to 1000 micrometersinfravörös sugárzás
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 materialionizáló sugárzás
non-ionising radiation Radiation that does not change the structure of atoms but does heat tissue and may cause harmful biological effectsnem-ionizáló sugárzás
radiation damage Somatic and genetic damage to living organisms caused by exposure to ionizing radiationsugárzás okozta kár
radiation dose The total amount of radiation absorbed by material or tissues, in the sense of absorbed dose, exposure dose, or dose equivalentsugárzásdózis
radiation effect Prolonged exposure to ionizing radiation from various sources can be harmful. Nuclear radiation from fallout from nuclear weapons or from power stations, background radiation from substances naturally present in the soil, exposure to X-rays can cause radiation sickness. Massive exposure to radiation can kill quickly and any person exposed to radiation is more likely to develop certain types of cancer than other members of the populationsugárzáshatás
radiation exposure The act or state of being subjected to electromagnetic energy strong enough to ionize atoms thereby posing a threat to human health or the environmentsugárzásexpozíció
radiation monitoring The periodic or continuous surveillance or analysis of the level of radiant energy present in a given area, to determine that its prescribed amount has not been exceeded or that it meets acceptable safety standardssugárzásmonitoring
radiation physics The study of ionizing radiation and its effects on mattersugárfizika
radiation protection Precautionary actions, measures or equipment implemented to guard or defend people, property and natural resources from the harmful effects of ionizing energysugárvédelem
radiation protection law A binding rule or body of rules prescribed by government to establish measures to keep humans and natural resources safe from harmful exposure to energy waves released by nuclear materials, electromagnetic current and other sourcessugárvédelmi törvény
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 energysugárbetegség
ultraviolet radiation The part of the electromagnetic spectrum with wavelengths shorter than light but longer than x-rays; in the range of 4-400 nmultraibolya sugárzás
