Description

Radiation doses in air at 7 points in Saitama Prefecture were measured by thermoluminescence dosimeter from 2008 to 2013. Annual radiation doses at 7 points in 2008 and 2009 were 0.40#approx#0.69 mGy/y and 0.40#approx# 0.68 mGy/y, respectively. These values were similar to those before 2007. However, annual radiation doses in air at all points, except 1 point where the measurement place was changed, increased after 2010. And the value in 2011 was the highest. It was thought that the cause of radiation doses increase was Fukushima Dai-ichi Nuclear Power Plant Accident occurred on Mar. 11, 2011. (author)

Abstract (Japanese)

2008~2013年度にかけて,TLDを用いて県内7か所の空間放射線量を測定した。年間空間放射線量は,2008年度は0.40~0.69 mGy/年及び2009年度は0.40~0.68 mGy/年であり,2007年度以前の値と同程度であった。2010年度からは測定地点の変更のあった1か所を除く全ての地点で増加がみられ,2011年度に最も高い値を示した。年間空間放射線量が増加した原因については,2011年3 月11日に発生した福島原発事故の影響と推測された。(著者)
