Tim Cama reports that radiation from the 2011 Fukushima Dai-ichi nuclear power plant radiation issues has reached the United States, but will likely peak by the end of next year. Cama used the anti-nuclear term, disaster, when the disaster was actually the 20,000 people that died as a result of the tsunami. No one has died from radiation or has even had radiation sickness. Disaster - another example of how the anti-nuclear activists make word-choice selections for the purpose further frightening the reader.

Research published Monday in the Proceedings of the National Academy of Sciences concluded that even at its highest level, concentrations of cesium-137 from Fukushima will be far lower than levels considered safe for drinking water in the United States and Canada. The study authors said their research is the first systematic study of the transportation of radioactive cesium-137 and cesium-134, both byproducts of nuclear power generation, from the Fukushima plant. Both cesium isotopes were already present in the Pacific Ocean because of nuclear weapons testing in the 1950s and 1960s, but the 134 isotope has a much shorter half-life.

Previous research has reached similar conclusions, but the publication includes the latest data, gathered in February 2014. It found that radiation started to reach the continental shelf off of Canada last year and has increased since then. It confirmed previous findings that radiation levels in the Pacific are 500 to 1,000 times smaller than that from dental X-rays. Following the peak late next year of radiation, concentrations will start to fall, the authors said, which means that the radiation will fall to insignificant levels from a health perspective.
