* When I visited Okuma in October, my scintillation meter measured contamination as high as 41.5 micros per hour. (Had this level been sustained, it would work out to 363.54 millis per year.) Fortunately, my dosimeter readings in this red zone averaged only 3.033 micros an hour, which would be 26.57 millis a year. Most of the time I was shielded in a vehicle, which surely reduced my dose.
