The Japanese Nuclear Leak in Perspective

By July 20, 2007Energy

From our friends at the NEI Nuclear Notes blog:

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.

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.

Bottom line, the We Support Lee blog asserts, the radiation leaked into the environment was insignificant. Which is certainly the case, despite all those who would monger comparisons to Chernobyl.
