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.
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.
The book suggests that radium-228 exposure is more harmful to health than exposure to radium-226. Radium-228 is more likely to cause cancer of the bone as the shorter half-life of radon-220 compared to radon-222 causes the daughter nuclides of radium-228 to deliver a greater dose of alpha radiation to the bones. It also considers the induction ...
The Radiation Exposure Compensation Act (RECA), the quarter-century old law that compensates Americans sickened by U.S. nuclear testing, expired this summer, but two Native American women are ...
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.
The embryo and fetus are considered highly sensitive to radiation exposure. [8] Complications from radiation exposure include malformation of internal organs, reduction of IQ, and cancer formation. [8] The SI unit of exposure is the coulomb per kilogram (C/kg), which has largely replaced the roentgen (R). [9]
Exposure to radiation causes chemical changes in gases. The least susceptible to damage are noble gases , where the major concern is the nuclear transmutation with follow-up chemical reactions of the nuclear reaction products.
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] There is a direct quantitative relationship between the magnitude of the neutropenia that develops after exposure to radiation and the increased risk of developing infection. Because no ...
