Measurement results of radiation doses in the air / Measurement results by the day (Kodaira)
News about this monitoring post
Due to a power outage at our center due to statutory inspection of electrical equipment, we will temporarily suspend updating of monitoring post measurement values from 8:00 to 19:00 on Saturday, October 18, 2025.
Due to a statutory inspection of electrical equipment at the Medicinal Plant Garden, measurements at the monitoring posts will be temporarily suspended from approximately 9:00 a.m. to approximately 11:00 a.m. on Monday, October 27, 2025.
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).
