The accidental or hostile exposure of individuals to ionizing irradiation is of great public and military concern. Radiation sickness (acute radiation syndrome, or ARS) occurs when the body is exposed to a high dose of penetrating radiation within a short period of time. Systemic infection is one of the serious consequences of ARS. There is a direct relation between the magnitude of radiation exposure and the risk of developing infection. The risk of systemic infection is higher whenever there is a combined injury such as burn or trauma. Ionizing radiation enhances infection by allowing translocation of oral and gastrointestinal flora, and reducing the threshold of sepsis due to endogenous and exogenous microorganisms. The potential for concomitant accidental or terrorism-related exposure to bio-terrorism agents such as anthrax and radiation also exists.

This site is made of a home page that presents new developments and updates on the management of acute radiation syndrome including concomitant exposure to radiation and anthrax. Separate pages are dedicated to the treatment modalities.

Attempts to prevent further explosions at Japan nuclear plants

After stopping highly radioactive water from flowing into the Pacific Ocean, workers at Japan's nuclear power complex are attempting to prevent more hydrogen explosions. Workers are cooling down the plant's reactors, which have been overheating since March 11. Because they are unable to restore normal cooling systems workers have resorted to pumping water into the reactors and letting it gush wherever it can. Technicians were expected to start pumping nitrogen into an area around one of the plant's six reactors to counteract the hydrogen. The injection could release radioactive vapor into the environment. They want to prevent hydrogen explosions at all costs because they could spew radiation and damage the reactors.
