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.

Threats and hazards to staff at Russian-seized Chernobyl nuclear power plant (NPP)

     Although the Chernobyl NPP stopped producing electricity around 2000, it still needs staff to keep cool water circulating over the spent fuel rods. Since the war cut the high-voltage power lines that normally, keep the NPP cooling system running, the staff have been held there at gunpoint working nonstop. There have been disagreements over what will happen if the pumps stop working: will the water boil, forming radioactive steam and then melting the fuel assemblies, or have the decades in storage cooled the fuel below the temperatures needed to cause a meltdown? 

A more probable and pressing radiation hazard is whether the outage will compromise the ventilation system, exposing the staff to higher levels of radiation. In any case, the staff being forced to do double duty (no relief staff for the second 12-hour shift), rapidly dwindling food supplies, lack of sleep, and armed Russian guards ready to shoot whoever tries to leave is severely stressing the staff to the point where someone may do something irrational.
