Leukemia rates vs. x-ray exposure

High-Strength Radiation

Increased rates of cancer also have been detected in people exposed to high-strength forms of radiation such as X-rays or radiation emitted from radioisotopes. Because these two types of radiation are stronger than ultraviolet radiation, they can penetrate through clothing and skin and into the body. Therefore, high-strength radiation can cause cancers of internal body tissues. The cancer-causing ability of high-strength radiation has been shown in several instances. Examples include cancer caused by nuclear fallout from atomic explosions and cancers caused by excessive exposure to radioactive chemicals.
