ちなみに放射線量モニタリングは福島原発事故前から行われているものです。また事故を受け行われていた降雨、飲料水、牛乳のモニタリングは、福島原発からの放射性物質放出量減少により、5/3で終了しています(通常の定期検査に戻る) http://p.tl/ZUZF @farposting

In response to the Japanese nuclear incident, EPA accelerated and increased sampling frequency and analysis to confirm that there were no harmful levels of radiation reaching the U.S. from Japan and to inform the public about any level of radiation detected. After a thorough data review showing declining radiation levels, on May 3, 2011, EPA returned to the routine RadNet sampling and analysis process for precipitation, drinking water and milk. As always, our 24/7 air monitoring stations continue to measure radiation levels, alerting scientists to even slight changes. It is important to note that all of the radiation levels detected by RadNet monitors and sampling have been very low, well below any level of public health concern. Across the RadNet system, we saw decreasing radiation levels during April and May. Since May, sample analyses have predominantly shown no detecti...
