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.
Douglas Harris Crofut (November 6, 1942 – July 27, 1981) was an American radiographer who inspected oil and natural gas pipelines. He died in intensive care as a result of radiation burns and radiation poisoning.
The effects of the 1979 Three Mile Island nuclear accident are widely agreed to be very low by scientists in the relevant fields. The American Nuclear Society concluded that average local radiation exposure was equivalent to a chest X-ray and maximum local exposure equivalent to less than a year's background radiation. [1]
Amid concerns about Russian President Vladimir Putin’s recent nuclear threats came a bit of startling news: The U.S. Department of Health and Human Services said Tuesday that it spent $290 ...
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
For comparison, the average background radiation in the United States is 310 mrem (3 mSv) a year. Chronic doses above 20 rem (0.2 Sv) increase the risk of cancer. Acute doses of 500 rem (5 Sv) kill half of those affected without medical treatment. [14] Chronic doses (received over a longer period of time) are less damaging than acute doses. [15]
The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).
These cleanup workers received hundreds of times of the average annual radiation dose allowed in the United States. Statistics on the numbers of deaths, illnesses and genetically produced mutagenic diseases in the following generations remains in debate depending on the source of information. The statistics vary from 4,000 deaths to 93,000 deaths.
