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.
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 ).
Three weeks later, the worker suffered symptoms typical of acute radiation syndrome (vomiting, loss of hair, fatigue). One estimate that he was exposed to a dose of between 4.4 and 4.8 Gy due to a malfunction of the control-command hydraulic system maintaining the radioactive source in the pool.

The signs and symptoms of ARDS often begin within two hours of an inciting event, but have been known to take as long as 1–3 days; diagnostic criteria require a known insult to have happened within 7 days of the syndrome. Signs and symptoms may include shortness of breath, fast breathing, and a low oxygen level in the blood due to abnormal ...
Acute radiation proctitis — symptoms occur in the first 3 months after therapy. [4] These symptoms include diarrhea and the urgent need to defecate. Radiation associated vascular ectasias (RAVE) and chronic radiation proctopathy — previously known as "chronic radiation proctitis" occur 3-6 months after the initial exposure. RAVE is ...
Early radiation enteropathy is very common during or immediately after the course of radiotherapy. This involves cell death, mucosal inflammation and epithelial barrier dysfunction. This injury is termed mucositis and results in symptoms of nausea, vomiting, fatigue, diarrhea and abdominal pain. [1] [6] It recovers within a few weeks or months.
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.
