A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation.
The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
Erythema ab igne in a person with chronic abdominal pain who found some relief from the application of heat. Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead ...
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months. [1][3][5] Early symptoms are usually ...
Phonophoresis can be performed using two main methods: The first is simultaneous treatment, where the drug can be applied at the same time as the ultrasound. The second method is pretreatment, where the ultrasound is used briefly before drug delivery. [8] [9] [13] [7] This is to ensure that the skin is permeable prior to the drug being applied.
Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. [10] It occurs when skin cells grow uncontrollably, forming malignant tumors. The primary cause of skin cancer is prolonged exposure to ultraviolet (UV) radiation from the sun ...
Actinic keratosis (AK), sometimes called solar keratosis or senile keratosis, [ 1 ][ 2 ] is a pre-cancerous [ 3 ] area of thick, scaly, or crusty skin. [ 4 ][ 5 ] Actinic keratosis is a disorder (-osis) of epidermal keratinocytes that is induced by ultraviolet (UV) light exposure (actin-). [ 6 ] These growths are more common in fair-skinned ...
A hydrofluoric acid burn is a chemical burn from hydrofluoric acid. [1] Where it contacts the skin it results in significant pain, swelling, redness, and skin breakdown. [1][2] If the fumes are breathed in swelling of the upper airway and bleeding may occur. [2] Complications can include electrolyte, heart, lung, kidney, and neurological ...
