| răşină |
resin (Any of a class of solid or semisolid organic products of natural or synthetic origin with no definite melting point, generally of high molecular weight; most resins are polymers) |
|
| răcire |
cooling (Setting aside a highly radioactive material until the radioactivity has diminished to a desired level) |
|
| răcirea clădirilor |
cooling of buildings |
|
| rădăcină |
root (The absorbing and anchoring organ of a vascular plant; it bears neither leaves nor flowers and is usually subterranean) |
|
| rămăşiţe animale |
animal remain (Any substances or components left over from animal life, including body parts and, later, decomposed materials) |
|
| răspundere extinsă a producătorilor |
extended producer responsibility |
|
| răspuns în caz de dezastre |
disaster response |
|
| răspândire a populaţiei |
population distribution (The density, dispersal pattern and apportionment of the total number of persons in any area) |
|
| răspândire geografică a populaţiei |
geographical distribution of population (The number of inhabitants in or spread across designated subdivisions of an area, region, city or country) |
|
| răsturnare |
overturn (The circulation, especially in the fall and spring, of the layers of water in a lake or sea, whereby surface water sinks and mixes with bottom water; it is caused by changes in density differences due to changes in temperature, and is especially common wherever lakes are icebound in winter; limnology) |
|
| război |
war (A conflict or a state of hostility between two or more parties, nations or states, in which armed forces or military operations are used) |
|
| război ecologic |
environmental warfare (The direct manipulation or destruction of ecological resources as either a political threat or for actual military advantage) |
|
| rața moțată |
comb duck |
|
| 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) |
|
| radiaţie |
radiation (Emission of any rays from either natural or man-made origins, such as radio waves, the sun's rays, medical X-rays and the fall-out and nuclear wastes produced by nuclear weapons and nuclear energy production. Radiation is usually divided between non-ionizing radiation, such as thermal radiation (heat) and light, and nuclear radiation. Non-ionizing radiation includes ultraviolet radiation from the sun which, although it can damage cells and tissues, does not involve the ionization events of nuclear radiation) |
|
| radiaţie 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) |
|
| radiaţie 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) |
|
| radiaţie cosmică |
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) |
|
| radiaţie de fond |
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) |
|
| radiaţie gamma |
gamma radiation (Radiation of gamma rays) |
