What is Radiation burn
A radiation burn is damage to the skin or other biological tissue caused by exposure to radio frequency energy or ionizing radiation.
The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation 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. Radiation burns are often associated with cancer due to the ability of ionizing radiation to interact with and damage DNA, occasionally inducing a cell to become cancerous. Cavity magnetrons can be improperly used to create surface and internal burning. Depending on the photon energy, gamma radiation can cause very deep gamma burns, with 60Co internal burns common. Beta burns tend to be shallow as beta particles are not able to penetrate deep into the person; these burns can be similar to sunburn.
Radiation burns can also occur with high power radio transmitters at any frequency where the body absorbs radio frequency energy and converts it to heat. [1] The 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, 400 MHz, and 1 GHz. [2]

A burn recovery bed or burn bed is a special type of bed designed for hospital patients who have suffered severe skin burns across large portions of their body.
Generally, concentrated pressure on any one spot of the damaged skin can be extremely painful to the patient, so the primary function of a burn bed is to distribute the weight of the patient so evenly that no single bed contact point is pressed harder than any other.
Nuclear warfare and bomb tests are more complex because a person can be irradiated by at least three processes. The first (the major cause of burns) is not caused by ionizing radiation.
Thermal burns from infrared heat radiation.
Beta burns from shallow ionizing radiation (this would be from fallout particles; the largest particles in local fallout would be likely to have very high activities because they would be deposited so soon after detonation and it is likely that one such particle upon the skin would be able to cause a localised burn); however, these particles are very weakly penetrating and have
Because fluoroscopy involves the use of x-rays, a form of ionizing radiation, all fluoroscopic procedures pose a potential health risk to the patient. Radiation doses to the patient depend greatly on the size of the patient as well as length of the procedure, with typical skin dose rates quoted as 20-50 mGy/min. Exposure times vary depending on the procedure being performed, but procedure times up to 75 minutes have been documented. Because of the long length of some procedures, in addition to standard cancer-inducing stochastic radiation effects, deterministic radiation effects have also been observed ranging from mild erythema, equivalent of
One type of weight-distributing burn bed uses a series of interlinked inflatable air chambers which have the surface appearance of an upside-down egg carton. Although inflatable, the air chambers are maintained in a partially deflated state so that the air pressure can freely distribute itself. Heavier parts of the patient's body can sink deeper into the grid of chambers and the air moves to chambers with less weight.
Air volume in the chambers may be regulated so as to make the bed firmer when the patient is first being placed on the bed, and then air is released to allow for
In the case of a person who has had only part of their body irradiated then the treatment is easier, as the human body can tolerate very large exposures to the non-vital parts such as hands and feet, without having a global effect on the entire body. For instance, if the hands get a 100 Gy dose which results in the body receiving a dose (averaged over the entire body of 5 Gy) then the hands may be lost but radiation poisoning would not occur. The resulting injury would be described as localized radiation burn.
As described below, one of the
This type of burn bed is similar in construction to a typical water bed, except the surface covering of the water pool has a large amount of slack and extra folds of material around the perimeter of the pool.
To limit the depth of immersion into the burn bed water pool, the water's density may be increased by adding several hundred pounds of salt to the water, as is done with a relaxation float tank.
As the patient is placed onto the bed, they displace the water and can freely sink down into the pool, unlike a typical consumer water bed. As
Stereotactic radiation therapy is a type of external radiation therapy that uses special equipment to position the patient and precisely deliver radiation to a tumor. The total dose of radiation is divided into several smaller doses given over several days. Stereotactic radiation therapy is used to treat brain tumors and other brain disorders. It is also being studied in the treatment of other types of cancer, such as lung cancer. Also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.
Radiation protection, sometimes known as radiological protection, is the science of protecting people and the environment from the harmful effects of ionizing radiation, which includes both particle radiation and high energy electromagnetic radiation.
Ionizing radiation is widely used in industry and medicine, but presents a significant health hazard. It causes microscopic damage to living tissue, resulting in skin burns and radiation sickness at high exposures and cancer, tumors and genetic damage at low exposures.
The cause of cutaneous horns is still unknown, however it is believed that exposure to radiation can trigger the condition. This is evidenced by a higher rate of cases occurring on the face and hands, areas that are often exposed to sunlight. Other cases have reported cutaneous horns arising from burn scars.[1]
