English: Radiation Dose Chart by Randall Munroe as part of the webcomic xkcd (SVG version of ). In response to concerns about the radioactivity released by the Fukushima Daiichi nuclear disaster:Fukushima Daiichi nuclear disaster in 2011, and to remedy what he described as "confusing" reporting on radiation levels in the media, Munroe created a chart of comparative radiation exposure levels.
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 ...
The program seeks to develop prophylactic (disease preventing) and therapeutic drugs, such as Ex-Rad, that prevent and treat radiation injuries and to develop rapid high-precision analytical methods that assess radiation exposure doses from clinical samples and thus aid in the triage and medical management of radiological casualties.
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 ...
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.
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 ...
The ionizing radiation used in CT scans can lead to radiation-induced cancer. [13] Age is a significant factor in risk associated with CT scans, [14] and in procedures involving children and systems that do not require extensive imaging, lower doses are used. [15]
Ionizing radiation has deterministic and stochastic effects on human health. The deterministic effects that can lead to acute radiation syndrome only occur in the case of high doses (> ~10 rad or > 0.1 Gy) and high dose rates (> ~10 rad/h or > 0.1 Gy/h). A model of deterministic risk would require different weighting factors (not yet ...
