Terms for subject Environment (6528 entries)
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 population) spinduliuotės poveikis
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 environment) apšvita
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 standards) spinduliuotės stebėjimas
radiation physics (The study of ionizing radiation and its effects on matter) spinduliuotės fizika
radiation protection (Precautionary actions, measures or equipment implemented to guard or defend people, property and natural resources from the harmful effects of ionizing energy) apsauga nuo spinduliuotės
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 sources) apsaugos nuo spinduliuotės teisės aktai
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) spindulinė liga
radio (The process, equipment or programming involved in transmitting and receiving sound signals by electromagnetic waves) radijas
radio programme (A performance or production transmitted in sound signals with electromagnetic waves) radijo programa
radioactive contamination (Contamination of a substance, living organism or site caused by radioactive material) užteršimas radioaktyviosiomis medžiagomis
radioactive contamination radioaktyvioji tarša
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) užteršimo radioaktyviosiomis medžiagomis pašalinimas
radioactive dumping (Waste generated by the emission of particulate or electromagnetic radiation resulting from the decay of the nuclei of unstable elements) radioaktyviųjų medžiagų šalinimas
radioactive effluent radioaktyviosios nuotekos
radioactive effluents radioaktyvieji išmetalai
radioactive emission (The release of radioactive substances into the environment deriving from nuclear installations and from mining, purification and enrichment operations of radioactive elements) radioaktyviųjų medžiagų išmetimas
radioactive fallout (The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion) radioaktyviosios dulkės
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) radioaktyvusis teršalas
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) radioaktyvioji medžiaga
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) radioaktyvusis žymeklis
