Guest guest Posted September 1, 2003 Report Share Posted September 1, 2003 I agree with those that state radiation is not stored in fat cells. Radiation comes in two flavors, electromagnetic (think radio, gamma, x-rays or cosmic rays) and particulate (neutrons, helium nuclei, electrons). Electromagnetic radiation, which is massless and consists only of energy, passes through the body and transfers energy to tissues, causing cellular damage. Electromagnetic energy is not stored in cells. Particulate radiation, which can be much nastier, is best thought of as tiny bullets. Some of these tiny bullets, like alpha particles (helium nuclei) can't even penetrate human skin. Others, like neutron particles, are very penetrating and can only be stopped by dense material like lead or water. Both electromagnetic and particulate radiation contain types that ionize (steal an electron from) the atoms they encounter, thereby causing damage to tissues. The components of particulate radiation are the basic building blocks of matter--electrons, protons, and neutrons. Once a particle loses it's energy (through encountering a substance dense enough to stop it, or by exceeding it's life span), it is harmless, just like a bullet with no gun. My understanding is based upon my astrophysics degree and the years I spent aboard nuclear submarines. DJ Quote Link to comment Share on other sites More sharing options...

Guest guest Posted September 1, 2003 Report Share Posted September 1, 2003 Yes, UV radiation is part of the electromagnetic spectrum, of which visible light is also a small part. I don't often think of UV light as radiation myself, but it certainly is. Depending upon energy and wavelength, radiation can go through matter, or matter can absorb or reflect it (visible light). " The surface of the human body absorbs and reradiates photons at energies ranging between 1.61 and 3.18 electron volts. This is the visible light region of the electromagnetic spectrum and explains why we can see people but cannot see beneath their skin. To look beneath the skin at the body's internal structure you need photons at energies high enough to penetrate tissue and bone. Photons at energies between 20 and 150 electron volts are ideal for diagnostic imaging purposes. These photons are X rays. " DJ Quote Link to comment Share on other sites More sharing options...
