Large populations all over the globe continue to be exposed to low-level radiation. Sources include natural background radiation, widespread medical uses of ionizing radiation, releases and leakages from nuclear power and weapons manufacturing plants...

Ionizing radiation is any energy that causes the ionization of the substance through which it passes. As the radiation is emitted from a source, it detaches a charged particle from an atom or molecule, leaving the atom or molecule with an excess...

High-energy radiation with penetrating competence such as x rays and gamma rays which induces ionization in living material. Molecules are bound together with covalent bonds, and generally an even number of electrons binds the atoms together. However,...

Any form of radiation that is capable of removing an electron from an atom and thereby creating an ION. ALPHA PARTICLES, BETA PARTICLES and ELECTROMAGNETIC RADIATION such as X-RAYS and GAMMA RADIATION are all forms of ionising...

Ionizing radiation is energetic particles or waves that have the potential to ionize an atom or molecule through atomic interactions. It is a function of the energy of the individual particles or waves, and not a function of the number of particles or...

The U.S. Department of Health and Human Services (HHS) released the 11 th edition of the Report on Carcinogens on January 31, adding ionizing radiation and several viruses to a growing list of eancer-causing agents, bringing the total to 246. The report, referred to...

I read with interest the recent review by Belson et al. (2007) on childhood leukemia, particularly the sections dealing with radiation exposure. Like the authors, I believe that ionizing radiation is strongly associated with childhood acute leukemia. I would like to point out...

The government proposed Tuesday relaxing its rules on labeling of irradiated foods and suggested it may allow some products zapped with radiation to be called "pasteurized."The Food and Drug Administration said the proposed rule would require companies to label irradiated food only when the radiation...

   Each year, approximately two hundred thousand American women are diagnosed with breast cancer. Five to ten percent of them have a hereditary form of this disease.    Changes in certain genes would make some women more susceptible to developing breast and other types of...
