Immunity and radiation

How ionizing radiation affects the body

When we talk about radiation exposure and its effects on the body, we usually mean ionizing radiation (IR) – the kind that can damage living tissue. The fact is, we are exposed to ionizing radiation every day either from natural sources (coming from radon, minerals, rocks, soil, and cosmic rays) or from man-made sources (from exposure to X rays, CT scans, radiotherapy, nuclear accidents and workplace radiation).
