Newly released data shows Florida hit with highest level of radioactive material from Fukushima measured anywhere in world outside Japan — #1 out of more than 1,500 test results — Total radioactive iodine was up to 500% of amount reported

Analysis of data from sensitive U.S. monitoring stations for the Fukushima Dai-ichi nuclear reactor accident, Journal of Environmental Radioactivity: [A] major nuclear event at the Fukushima Dai-ichi nuclear power station… resulted in a breach of the nuclear fuel integrity and release of radioactive fission products to the environment. Fission products started to arrive in the United States via atmospheric transport on March 15, 2011… Atmospheric activity concentrations of 131I reached levels of 3 x 10^-2 Bq/m³ [30,592 microBq/m³] in Melbourne, FL. The noble gas 133Xe reached atmospheric activity concentrations in Ashland, KS of 17 Bq/m³… [These levels] were well above the detection capability of the radionuclide monitoring systems within the International Monitoring System [IMS] of the Comprehensive Nuclear-Test-Ban Treaty [CTBTO]… it should be noted that non-IMS stations located in Richland, WA detected the event one day earlier than any other systems within the US IMS network… The iodine detections reported in this manuscript are solely representative of the particulate iodine atmospheric activity concentration. It is recognized that the gas phase iodine was not collected via aerosol filtration [which] would be useful to assess the event and to quantify the total radioiodine atmospheric activity concentration.
