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.

Reheating concern in the Fukushima reactor in Japan

Concern is growing that the Fukushima Daiichi nuclear power plant is no longer stable after temperature readings indicated that one of its damaged reactors was reheating.
The temperature inside No 2 reactor may have reached 82C on today.
Tepco increased the amount of cooling water injected into the reactor along with a boric acid solution, which is used to prevent the fuel from undergoing sustained nuclear reactions.
The reheating may force the government to reverse its declaration two months ago that the crippled plant was in a safe state known as cold shutdown.
Tepco stated that the cause of the t temperature rise is unkown, and might be due to problems with the supply of coolant or a faulty thermometer.
Tepco was previously forced to inject additional cooling water into the same reactor last week after the temperature started rising.
