Let me make something clear at the outset: All over the world, the nuclear industry takes the events in Japan very seriously. With that in mind, here's some proper perspective from We Support Lee on just how much radioactive material was released from the Kashiwazaki-Kariwa nuclear power plant this week:
According to news sources, the leak of radiation at the Kashiwazaki-Kariwa nuclear power plant in Japan was 90,000 Becquerels, which is one billionth of the legal limit for radioactivity release.So when others start to compare this incident to Chernobyl, please keep this in mind.
90,000 Bq (Becquerels) means 90,000 disintegrations per second.
How much is 90,000 Bq in the medical world? Medical patients regularly receive 240 million Becquerels during treatments for hyperthyroidism. That's 2667 times what was released into the Sea of Japan.
These patients, some of whom are probably at a clinic in your town right now, watch tv, walk around, sit, talk, read, and disintegrate 131I at 2667 times the rate that the Kashiwazaki-Kariwa Nuclear Power Plant's release in the Sea of Japan is decaying.
The bottom line is that the radiation released during the earthquake is insignificant.
