大気中の放射線量/１時間ごとの測定結果（新宿）
（Environmental radiation levels in Shinjuku / 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。
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。
