Some people may worry about radiation in Hiroshima, even it’s been 70 years since the atomic bomb fell.
Actually I read some people’s post that worry about radiation on some English sites.
So I’ve decided to try to reassure everyone.
I bought a machine to measure the radiation (radiation detector).
“AIR COUNTER S” is made by S.T. CORPORATION in Japan.
The machine’s simple, but the performance is good.
Many people have left a review. It is helpful and take a fairly accurate number.
Now I’m in front of the Bomb Dome.
The manual of the machine says that measuring several times and calculating the average value is recommended.
So I’ll measure 3 times.
1st time. 0.06 μSv/h
2nd. 0.14 μSv/h
3rd. 0.07 μSv/h
So, the average is
According to the manual,
0.09 μSv/h (micro sievert per hour) is equivalent to 0.75 mSv/year (millisieverts per year).
The average in Japan is 1.5 mSv/year.
The average in the world is 2.4 mSv/year.
With respect to radiation, Hiroshima seems very safe.
So everyone, don’t be afraid and please come to Hiroshima!
