In our modern age, there are special plastic shields which stop […]
There are three cardinal rules of radiation protection and they are all used by X-ray professionals. Time: During an X-ray, the beam is produced only long enough to obtain a good image. That time will vary greatly due to factors such as size or the atomic structure of the area being examined. For people who […]
The biological effects of radiation are thought of in terms of their effects on living cells. For low levels of radiation, the biological effects are so small they may not be detected in epidemiological studies. The body repairs many types of radiation and chemical damage. Biological effects of radiation on living tissue may result in […]
