An atomic veteran is a veteran who was exposed to ionizing radiation while present in the site of a nuclear explosion during active duty.The U.S. Department of Veterans Affairs defines an atomic veteran "who, as part of his or her military service: Participated in an above-ground nuclear test, 1945–1962; or was part of the U.S. military occupation forces in/around Hiroshima/Nagasaki before ...
Ionizing radiation is used in a wide variety of fields such as medicine, nuclear power, research, and industrial manufacturing, but is a health hazard if proper measures against excessive exposure are not taken. Exposure to ionizing radiation causes cell damage to living tissue and organ damage.
Its objective "is to develop concepts, definitions and recommendations for the use of quantities and their units for ionizing radiation and its interaction with matter, in particular with respect to the biological effects induced by radiation". [1] The ICRU is a sister organisation to the International Commission on Radiological Protection (ICRP).
[1] [2] Numerous studies have demonstrated that the susceptibility of organisms to systemic infection increased following exposure to ionizing radiation. [1] The risk of systemic infection is higher when the organism has a combined injury, such as a conventional blast, thermal burn, [ 3 ] or radiation burn . [ 2 ]
Thousands of veterans who say they were sickened by radiation exposure during their military service have been denied federal benefits, the Department of Veterans Affairs said, as cancer and old ...
The linear no-threshold model (LNT) is a dose-response model used in radiation protection to estimate stochastic health effects such as radiation-induced cancer, genetic mutations and teratogenic effects on the human body due to exposure to ionizing radiation. The model assumes a linear relationship between dose and health effects, even for ...
Radiation dosimetry in the fields of health physics and radiation protection is the measurement, calculation and assessment of the ionizing radiation dose absorbed by an object, usually the human body. This applies both internally, due to ingested or inhaled radioactive substances, or externally due to irradiation by sources of radiation.
Radiation is a moving form of energy, classified into ionizing and non-ionizing type. [4] Ionizing radiation is further categorized into electromagnetic radiation (without matter) and particulate radiation (with matter). [4] Electromagnetic radiation consists of photons, which can be thought of as energy packets, traveling in the form of a wave ...
