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.

World Health organization releases Fukushima radiation report

The preliminary report from the World Health Organisation (WHO) report published on May 23, 2012 stats that radiation levels in most of Japan are lower than cancer-causing levels a year following the Fukushima plant accident. While two areas close to the plant have relatively higher levels of radiation, but radiation levels in surrounding countries are almost normal.
A different finding from a UN scientific committee stated that several workers at the Fukushima plant had been "irradiated after contamination of their skin". The statement issued as interim findings by the United Nations Scientific Committee on the Effects of Radiation (UNSCEAR) was that "Six workers have died since the accident but none of the deaths were linked to irradiation".
Namie town and Itate village, that are close to the Fukushima plant in eastern Japan, are currently exposed to radiation levels of 10-50 millisieverts (mSv), while the radiation levels at the rest of Fukushima are 1-10 mSv, the WHO report said. Most of Japan has levels of 0.1-1 mSv, while neighbouring countries have less than 0.01 mSv.
These findings should be assessed taking into consideration that the single-year limit for occupational exposure of workers is 50 mSv. Most individuals are exposed on average to around 2 mSv of radiation a year from the natural environment.
