RICHLAND — The homes of seven Hanford Nuclear Reservation workers in Washington state are being inspected after a spread of radioactive contamination in recent days.
The total number of vehicles reported to be contaminated with apparent specks of radioactive material increased to 14 from the eight reported Tuesday.
The Tri-City Herald reports at least two of those vehicles may have been driven home by workers demolishing the Plutonium Finishing Plant.
Hanford workers with contaminated vehicles requested surveys of their homes to make sure they had not tracked contamination home. No contamination was found inside worker vehicles.
Employees of the Washington state Department of Health are accompanying Hanford officials on the home checks to observe and verify results.
Hanford is located near Richland and for decades made plutonium for nuclear weapons.
