大気中の放射線量/1時間ごとの測定結果(八王子)
(Environmental radiation levels in Hachioji / 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
モニタリングポスト(八王子局)は、施設の工事及び設備点検による停電のため、以下の日時に測定を一時的に停止します。
1 2025年8月16日(土曜日)午前8時頃から2025年8月17日(日曜日)午前8時頃まで
2 2025年10月26日(日曜日)午前7時頃から午後6時頃まで
3 2025年11月22日(土曜日)午前7時30分頃から午前8時頃まで
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。
