-At approx. 12:40 pm on September 14, 6 partner company’s workers, who maintained water treatment faculties, conducted contamination check of full-face masks when they returned from the work site to 1F’s Main Anti-Earthquake Building.
As a result, inner side of the filter for 4 out of the 6 workers were confirmed to be contaminated.
We will confirm whether the 6 workers might have absorbed contaminated materials inside of their bodies using whole body counter.
