Survey meter measurement of radiation levels (from July 25, 2011 to July 31, 2017)

In Hokkaido tourist spots, radiation levels are normal.

We are confident that you will be able to enjoy the trip to Hokkaido just like the same as before.

We are looking forward to seeing you in Hokkaido.

Radiation levels are measured at one meter high from the ground.

 Note

1. μ (micro) means the parts per million. m (milli) means the parts per thousand.

2. Radiation levels are measured in nGy/h (nano-Gray per hour). 1 nGy/h is equivalent to 0.001 μGy/h.

3. Sv (sievert) is the unit you often hear in the news. This indicates the energy amount absorbed from radiation

 into a person’s body. In such an emergency circumstance, it is reasonable to think 1 Sv = 1Gy.

4. Radiation levels may temporarily increase on rainy days, because rain contains a little amount of

  natural radioactive substance.
