The Party Line – August 5, 2011: Japan Worries About More Radiation, US Officials Worry About Red Tape
News this week out of Japan that workers at the crippled Fukushima Daiichi nuclear plant have detected extremely high levels of radiation in and around reactor 1. The first incident, on August 1, pinned the Geiger counter at 10 sieverts (1000 rem)—yes, that’s as high as the device could measure, so that number is a minimum—and was taken at the base of a ventilation stack. The second reading, the following day, clocked in at five sieverts per hour inside the reactor building.
I have yet to read an explanation for the discovery of the second reading, but the initial, sky-high measurement on Monday has me and many others scratching heads. A thousand rem is not some little ho-hum number. A half-hour of exposure at that level is fatal in a matter of days, I am told. Where did that radiation come from? When did contamination occur? How is it that such a dangerous level could go unreported for what is now over 140 days?
Officials from the Japanese power company, TEPCO, who have been repeatedly criticized for withholding critical information, insist that contamination likely happened in the first few days of the disaster when workers tried to vent hydrogen from the reactor building in a futile attempt to prevent an explosion. Somehow, though, this part of the facility (which, it should be noted, has been extensively mapped for radioactive hotspots over the last several months) was not measured till August.
