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.
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 ...
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.

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 ...
Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. It can be either detrimental or beneficial for materials.
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.
