Some EPA Japan-Radiation Monitors May Not Be Working Properly

Eight of 18 air monitors in California, Oregon and Washington state that track radiation from Japan’s nuclear reactors are “undergoing quality review,” according to the Environmental Protection Agency’s website.

A sufficient number of devices are working and can measure any changes in radiation levels from the damaged Fukushima Dai-Ichi reactors, said Ronald Fraass, director of the EPA’s National Air and Radiation Environmental Laboratory in Montgomery, Alabama.
