Measurement results of radiation doses in the air / Measurement results by the day (Shinjuku)
Shown in µGy/h (microgray per hour)
Gray indicates an amount of energy (absorbed dose) when radiation hits a material object, and 1 gray (Gy) of radiation doses in the air can be converted to 1 sievert (Sv).
