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.
Unlike some other sources of radiation, polonium-210 emits very little gamma radiation, but large amounts of alpha particles which are relatively difficult to detect with common radiation detectors such as Geiger counters. This explained why tests conducted by doctors and Scotland Yard at the hospital with Geiger counters were negative.
Average radiation doses received in Germany. Radon accounts for half of the background dose; and medical doses reach the same levels as background dose. The largest natural contributor to public radiation dose is radon, a naturally occurring, radioactive gas found in soil and rock, [65] which comprises approximately 55% of the annual background ...
His illness was later attributed to poisoning with radionuclide polonium-210 after the Health Protection Agency found significant amounts of the rare and highly toxic element in his body. [ 98 ] Litvinenko met with two former agents early on the day he fell ill – Dmitry Kovtun and Andrey Lugovoy , in the Pine Bar of the Millennium Hotel where ...
Polonium-210 (210 Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206 Pb with a half-life of 138.376 days (about 4 + 1 ⁄ 2 months), the longest half-life of all naturally occurring polonium isotopes ( 210–218 Po). [ 1 ]
Polonium was named after Marie Skłodowska-Curie's homeland of Poland, which at the time was partitioned between three countries. Polonium has few applications, and those are related to its radioactivity: heaters in space probes, antistatic devices, sources of neutrons and alpha particles, and poison (e.g., poisoning of Alexander Litvinenko ...
Allegations that Silkwood's exposure to plutonium-239 was a deliberate act of radiation poisoning are fueled by the fact that she was in possession of potentially compromising evidence that linked Kerr-McGee with egregious safety violations, encompassing unsafe workplace conditions at the plant, faulty manufacture of fuel rod components that ...
Radiation-induced lung injury (RILI) is a general term for damage to the lungs as a result of exposure to ionizing radiation. [1] In general terms, such damage is divided into early inflammatory damage ( radiation pneumonitis ) and later complications of chronic scarring ( radiation fibrosis ).
