大気中の放射線量/1時間ごとの測定結果(江東)
(Environmental radiation levels in Koto / hour)

モニタリングポストでは、空間放射線量率(1時間当たりの空気吸収線量)を連続的に測定しています。測定結果は1分ごとに得られ、これを1時間ごとに、あるいは1日ごとにまとめて表示しています。

最大値は各時間帯(1時間のうち、あるいは1日のうち)で測定された最大の値、最小値は各時間帯で測定された最小の値、平均値は各時間帯の平均値です。

このモニタリングポストに関するお知らせ

2025年10月18日(土曜日)8時から19時までの間、電気設備の法定点検に伴う当センターの停電により、モニタリングポストの測定値の更新を一時停止いたします。

単位はμGy/h(マイクログレイ/時間)
グレイは放射線が物質に当たった時のエネルギー量を表し、大気中の放射線量1グレイは1シーベルトに換算できます。
