The effect of ionizing radiation on the whole organism is discussed in this chapter data on the various forms of the acute radiation syndrome (ars.
Acute radiation syndrome (ars) is classically described as having three sub-syndromes: the haemopoietic (1 gy), the gastro-intestinal (3. Exposure to radioactive material - even in small doses - can be fatal but at lesser levels and depending on the material you're exposed to, you may only feel minor discomfort. The acute radiation syndrome (ars) occurs after whole-body or significant partial-body irradiation (typically at a dose of 1 gy) ars can involve the hematopoietic, cutaneous, gastrointestinal and the neurovascular. The main objective of the parent project, joint collaborative committee for radiation effects research (jccrer) project 23, is the development of a database of mayak pa workers to use for such purposes as the verification of current dose-effect models for deterministic effects of acute exposure including the acute radiation syndrome or ars.

Radiation sickness is also called acute radiation sickness, acute radiation syndrome or radiation poisoning common exposures to low-dose radiation.
Acute radiation syndrome clinical picture, diagnosis and treatment. Acute radiation syndrome radiation sickness, known as acute radiation sickness (ars), is a serious illness that occurs when the entire body (or most of it) receives a high dose of radiation, usually over a short period of time. Acute radiation syndrome (ars) also known as radiation poisoning, radiation sickness or radiation toxicity, is a constellation of health effects which occur within several months of exposure to high amounts of ionizing radiation.

Acute radiation syndrome ( ars ) is a collection of health effects that are present within 24 hours of exposure to high amounts of ionizing radiation the radiation causes cellular degradation due to damage to dna and other key molecular structures within the cells in various tissues. Acute radiation syndrome (ars) is caused by exposure to a high dose of ionizing radiation over a short period of time, such as could occur after the meltdown of a nuclear reactor or the detonation of a “dirty bomb.
Illnesses collectively called acute radiation syndrome occur within a few hours to months after exposure to high-dose radiation (from approximately 1-2 gy to 10 gy. Acute radiation syndrome or acute radiation sickness is classically subdivided into three subsyndromes: the hematopoietic, gastrointestinal and neurovascular syndrome but many other tissues can be damaged. Exposure to high levels of penetrating radiation can involve the whole body (uniformly or non-uniformly), a significant portion of the body, or a small, localised part.
