A<unk>  is a damage to the skin or other biological tissue and organs as an effect of<unk> . The<unk>  types of greatest concern are thermal<unk> , radio frequency energy, ultraviolet light and ionizing<unk> . The most common type of<unk>  is a sunburn caused by UV<unk> . High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in<unk> s. As the ionizing<unk>  interacts with cells within the body—damaging them—the body responds to this damage, typically resulting in erythema—that is, redness around the damaged area.<unk> s are often discussed in the same context as<unk> -induced cancer due to the ability of ionizing<unk>  to interact with and damage DNA, occasionally inducing a cell to become cancerous. Cavity magnetrons can be improperly used to create surface and internal<unk> ing. Depending on the photon energy, gamma<unk>  can cause deep gamma<unk> s, with 60Co internal<unk> s common. Beta<unk> s tend to be shallow as beta particles are not able to penetrate deeply into a body; these<unk> s can be similar to sunburn. Alpha particles can cause internal alpha<unk> s if inhaled, with external damage (if any) being limited to minor erythema.<unk> s can also occur with high power radio transmitters at any frequency where the body absorbs radio frequency energy and converts it to heat. The U.S. Federal Communications Commission (FCC) considers 50 watts to be the lowest power above which radio stations must evaluate emission safety. Frequencies considered especially dangerous occur where the human body can become resonant, at 35 MHz, 70 MHz, 80-100 MHz, 400 MHz, and 1 GHz. Exposure to microwaves of too high intensity can cause microwave<unk> s.
