Document Summary
Out of the total exposure to radiation: medical treatments almost 90%, radiation is divided into two large groups based on wavelength. In the center is visible waves which you can see. Ionized radiation has high energy and short wavelength: nonionzed radiation has low energy and long wavelength. It can hit a atom and strip away electrons and that goes. Then that free electron can break some other bond: stochastic meaning (statistics) happens by chance, cancer is a very important health impact. In chance to get the cancer due to low dose of radiation is increased if the dose gets higher. If someone is exposed to more radiation, in comparison to some exposed to less cancer is higher for the person that is exposed to more. However, if both people get cancer, the one person exposed to higher dose will not have a more severe case or chance for complications. Our thyroid can not differentiate between the radioactive or normal.
