DOIAbstract
Environmental radiation at Izu-Oshima Island was observed six months after the accident at the Fukushima Daiichi Nuclear Power Plant (F1-NPP). A car-borne survey of the dose rate in air was conducted over the entire island and the results were compared with measurements performed in 2005 (i.e., before the accident). The activity concentrations of cesium-134 and cesium-137 were also measured using a germanium detector. The dose rate in air was found to be 2.9 ± 1.2 times higher than that in 2005 and cesium-134 was detected on Izu-Oshima Island. These results are attributed to the accident at the F1-NPP
