IONIZING RADIATION (IR) INFORMATION FOR VETERANS AND THEIR FAMILIES WHAT IS IONIZING RADIATION? Ionizing radiation (IR) is high-energy radiation. Exposure to high doses of IR may cause adverse health effects. Sources. of IR exposure during military service include: •roximity to radioactive material P •se of calibration and measurement. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules, and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α. ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. While there are other, less energetic, types of non-ionizing radiation (including radio waves, microwaves—and visible light), this booklet is about ionizing radiation.
