(realtime update)
Fukushima Daiichi Nuclear Reactors are still leaking the nuclear radiation.
We have developed this service to minimize the negative effects.
Our website is using Korean and Japanese data at the same time for your convenience.

We use special web robots called STUBBY to track the radiation level in realtime from various web resources.

Some facts and figures about the radiation hazard(byScientific American)
Radiation dose at the boundary of the Fukushima Daiichi nuclear power station on March 16:
1.9 millisieverts (mSv) per hour

Peak radiation dose measured inside Fukushima Daiichi on March 15:
400 mSv per hour

Maximum allowable exposure for U.S. radiation workers:
50 mSv per year

Average exposure of U.S. residents from natural and man-made radiation sources:
6.2 mSv per year

Estimated total exposure at the boundary of the Three Mile Island site in Pennsylvania during the 1979 accident there:
one mSv or less

Average total radiation dose to the 114,500 individuals evacuated during the 1986 Chernobyl disaster:
31 mSv

Half-life of iodine 131, a dangerous radioactive isotope released in nuclear accidents:
eight days

Half-life of cesium 137, another major radionuclide released in nuclear accidents:
30 years

Decay products of iodine 131 and cesium 137:
both emit gamma rays and beta particles (electrons or positrons)

Amount of nuclear fuel in Chernobyl reactor No. 4 that exploded in 1986:
190 metric tons

Amount of nuclear fuel and fission by-products released into the atmosphere during Chernobyl disaster:
25 to 57 metric tons

Approximate amount of nuclear fuel in each crippled Fukushima Daiichi reactor:
70 to 100 metric tons

1 Sv(=Approx.0.8Gy) = 1,000 mSv (millisieverts) = 1,000,000 μSv (microsieverts) = 1,000,000,000 nSv (nanosieverts)
