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.
Background radiation is from naturally radioactive materials and cosmic radiation from space. [5] People are exposed to this radiation from the environment continuously, with an annual dose of about 3 mSv. [5] Radon gas is a radioactive chemical element that is the largest source of background radiation, about 2mSv per year. [17]
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 Senate passed legislation Thursday that would compensate Americans exposed to radiation by the government by renewing a law initially passed more than three decades ago. Josh Hawley, R-Mo ...
These were distributed and used in multiple cities across Mexico and the United States and exposed an estimated four thousand people to radiation. [85] 1985 to 1987: The Therac-25 accidents. A radiation therapy machine was involved in six accidents, in which patients were exposed to massive overdoses of radiation. 4 fatalities, 2 injuries. [86]
83 people were injured due to uneven cooling of the reactor core, resulting in fuel element failures and multiple ruptures. [12] 8 Soviet submarine K-19 reactor accident 1961, July 4 More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably.
There are more than 552,000 radiation-exposed veterans in the Defense Threat Reduction Agency’s database, said a spokesperson for the agency. About 46,000 of them have died, the agency said.
A 2015 report in Lancet explained that serious impacts of nuclear accidents were often not directly attributable to radiation exposure, but rather social and psychological effects. [19] The consequences of low-level radiation are often more psychological than radiological. Because damage from very low-level radiation cannot be detected, people ...
