The International Atomic Energy Agency (IAEA) released an update on the status of the Fukushima Daiichi nuclear power plant on Tuesday, March 15, 2011, 11: 25 a.m. UTC (7:26 p.m., Tokyo time)

According to the IAEA update on Facebook, a dose rate of 11.9 millisieverts (mSv) per hour was observed at the said plant as of March 15, 00:00 UTC, and dropped to 0.6 millisieverts (mSv) per hour six hours later, or 6 p.m. (UTC).

Earlier, a dose rate of 400 millisieverts (mSv) per hour radiation observed at Fukushima Daiichi occurred between units 3 and 4 was reported, which is high-dosage value, according to IAEA.

For easier understanding, IAEA noted that a person’s average normal radiation exposure due to all natural sources around him is about 2.4 millisievert (mSv) per year, where Sv is the unit of dose of radiation. A single X-ray exposure will give someone about 0.1 mSv of radiation dose.

Meanwhile, around 150 people from the Fukushima Daiichi site are now being monitored in terms of radiation level and 23 of them will be decontaminated, and IAEA said they will be continuously monitored closely.

As of this writing, the people within the 20-kilometer radius zone within the Fukushima Daiichi nuclear power plant are being continuously evacuated and was said to have reached to about 200,000, while people within the 30-kilometer radius are being strongly advised to stay indoors.

Incidentally, Aljazeera reported that the official number of casualties as of this moment is 2,414, and tens of thousands are still being unaccounted for.
