Preliminary Dose Estimates Fukushima Daiichi

Originally Published May 25, 2012; Last Updated June 03, 2016; Last Republished May 20, 2016:

World Health Organization releases a preliminary report on the preliminary dose estimates for the nuclear accident at Fukushima, Japan following the March 11, 2011 great earthquake and tsunami.

The report represents the first international effort to assess global radiation doses from the Fukushima Daiichi nuclear power plant accident considering all major exposure pathways.

"The study found [North America] concentrations (activity) and fallout (deposition) of radioactive iodine and radioactive cesium in significant number of samples. Detectable quantities of Iodine-131, Cesium-137, and Cesium-134 were observed at 21% of the 167 tested locations. Concentrations of I-131 detected in 5 samples ranged from 29.6 to 1090 picocuries per liter (pCi/L). Concentrations of Cs-134 detected in 23 samples ranged from 0.4 to 55 pCi/L. Concentrations of Cs-137 in 33 samples ranged from 0.70 pCi/L to 39 pCi/L."

NRC is implementing a National Academy recommendation (pdf) to revisit cancer risks to human cohorts from ionizing radiation within 50 km of a nuclear facility.

Phase I addresses feasibility, methodology, effected population, data quality and representative nuclear facility selection [Dresden Nuclear Power Station, Morris, Ill.; Millstone Power Station, Waterford, Conn.; Oyster Creek Nuclear Generating Station, Forked River, N.J.; Haddam Neck (decommissioned), Haddam Neck, Conn.; Big Rock Point Nuclear Power Plant (decommissioned), Charlevoix, Mich.; and San Onofre Nuclear Generating Station, San Clemente, Calif.] in preparation for the Phase II study.

TEPCO seems to have discovered a more effective method of transforming its already colossal radioactive cleanup tasks in to a disaster than by combing ignorance with organized crime—ignore audiable alarms signaling the leakage of 230 million becquerels per liter of Stronium 90!

It's difficult to imagine a more effective method of transforming radioactive cleanup in to a disaster than combining ignorance and organized crime.
