Now, why would X rays and gamma rays be dangerous? Well, what X rays and gamma rays are they're really, really strong beams that carry a great deal of energy. And when those X rays and those gamma rays hit the individual, those beams of energy can basically cause harm to the cells of that body as well as the cellular processes that take place within the body. So women who are exposed to ionizing radiation ionizing simply means once that beam hits those molecules, they ionize those molecules by basically bumping electrons to higher energy levels. So women who are exposed to ionizing radiation, such as X rays, gamma rays, et cetera, during pregnancy have a much higher chance of giving birth to children with different types of abnormalities, defects as well as cancer. So, for example, a woman who is pregnant probably shouldn't be prancing around some type of nuclear power plant, a power plant or a place like Chernobyl because those places contain very radioactive atoms and very radioactive sources.
