Radioactivity Value at Monitoring Stations in Ibaraki Prefecture


The data below is the average radioactivity value during a 10 minute period.

For reference:
**The air dose rate is displayed as nGy/h(nanogray/ hour) which is equal to the measurement of nSv/h(nanosievert/hour). The latter is used to measure the influence on humans.

1nGy/h(nanogray/hour) = 1nSv/h(nanosievert/hour)
**The radioactivity value of one chest x-ray is 50,000nSv (nanosievert)

**1000nSv(nanosievert) = 1Sv(microsievert) = 0.001mSv(millisievert)
