However, the current assumption is that there is no threshold of exposure below which x-radiation may not adversely effect human health. Scientists have not identified specific health effects resulting from exposure to extremely low doses of low-level radiation over prolonged periods of time. This unintentional emission of x-radiation can pose a potential hazard and must be controlled. These components may produce x-rays capable of escaping from the television receiver or CRT. Since many of the components in television sets operate at thousands of volts, there is the potential for x-ray generation. X-rays may be produced when electrons, accelerated by high voltage, strike an obstacle while traveling in a vacuum, as in a TV containing a cathode ray tube (CRT). ![]() In others, as with TV sets, radiation emitted is not intentional and is not essential to the use of the product. In some cases, as with diagnostic x-rays, radiation emitted from these devices is intentional and serves a useful purpose. These include diagnostic x-ray machines, television sets, microwave ovens, radar devices, and lasers. Much of the manmade radiation people are exposed to comes from electronic products. We are also exposed to manmade radiation, which can and must be controlled. This is called background radiation and cannot be controlled. We are surrounded by natural radioactivity in the earth and by cosmic rays from outer space. Man cannot escape exposure to some radiation. Putting Television Radiation in Perspective
