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.
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.
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.
The Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many years by Soviet authorities and has only come to light since the test site closed in 1991. [59] 2007 ISO radioactivity danger symbol ...
The Windscale fire resulted when uranium metal fuel ignited inside plutonium production piles; surrounding dairy farms were contaminated. [33] [34] The severity of the incident was covered up at the time by the UK government, as Prime Minister Harold Macmillan feared that it would harm British nuclear relations with America, and so original reports on the disaster and its health impacts were ...
This resulted in three deaths and affected 100+ people. A woman was exposed to radiation while nursing her sick husband. Her dose was estimated to be 2.3 Gy by means of a blood test 41 days after the accident, 16 years after the accident the woman has been subject to premature aging which may be a result of her radiation exposure.
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]
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.
