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 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 ...
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 ).
Radiation fibrosis syndrome (also known as radiation fibrosis or radiation-induced fibrosis) is a human illness. It occurs as a result of cell death , and can be caused by radiotherapy . It is characterized by the accumulation of fibrin in irradiated tissues.
High doses can cause visually dramatic radiation burns, and/or rapid fatality through acute radiation syndrome. Controlled doses are used for medical imaging and radiotherapy . Most adverse health effects of radiation exposure may be grouped in two general categories:
A dose of under 100 rad will typically produce no immediate symptoms other than blood changes. A dose of 100 to 200 rad delivered to the entire body in less than a day may cause acute radiation syndrome (ARS), but is usually not fatal. Doses of 200 to 1,000 rad delivered in a few hours will cause serious illness, with poor prognosis at the ...
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, by acute whole-body radiation; Radiation burns, from radiation to a particular body surface; Radiation-induced thyroiditis, a potential side effect from radiation treatment against hyperthyroidism; Chronic radiation syndrome, from long-term radiation. Radiation-induced lung injury, from for example radiation therapy to ...
