radioactivity levels

Local environmental groups have voiced concerns about the radioactivity levels of the cooling water of both these nuclear sites, which is being flushed into the bay of Vauville ; however, the emitted radioactivity is several orders of magnitude below natural background levels and does not pose any hazard.

A January 2005 report by the DOE stated that radioactivity levels were normal at the surface and in groundwater, though a later report due in 2007 is expected to more fully explore if there is subsurface contamination and whether or not radioactivity is still spreading outward from the blast site itself.

When used, the ionization chamber would be inserted into a yellow anti-contamination bag, tied off, and hung outside a bomb shelter to measure radioactivity levels from a safe distance.
