Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [ 1 ]
From Preston et al.: [1] Solid cancer dose-response function average over gender for attained age 70 after exposure at age 30. The solid straight-line is the linear slope estimate; the points are dose -category-specific ERR estimates; the dashed curve is a smoothed estimate that is derived from the points; and the dotted curves indicate upper ...
Children and adolescents are twice as likely to develop radiation-induced leukemia as adults; radiation exposure before birth has ten times the effect. [ 6 ] Radiation exposure can cause cancer in any living tissue, but high-dose whole-body external exposure is most closely associated with leukemia , [ 55 ] reflecting the high radiosensitivity ...
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.
Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive contamination. Ionizing radiation is widely used in industry and medicine, and can present a significant health hazard by causing microscopic damage to living tissue.
Exposing skin to infrared radiation near visible light (IR-A) leads to increased production of free radicals. [41] Short-term exposure can be beneficial (activating protective responses), while prolonged exposure can lead to photoaging. [42] Another important factor is the distance between the worker and the source of radiation.
Exposure to radiation causes chemical changes in gases. The least susceptible to damage are noble gases, where the major concern is the nuclear transmutation with follow-up chemical reactions of the nuclear reaction products. High-intensity ionizing radiation in air can produce a visible ionized air glow of telltale
