Fukushima Explosion: Japan Nuclear Plant Rocked By Hydrogen Explosion. SOMA, Japan - The second hydrogen explosion in three days rocked Japan's stricken Fukushima Dai-ichi nuclear plant Monday, sending a massive column of smoke into the air and wounding 6 workers. The plant's operator said radiation levels at the reactor were still within legal limits. The explosion at the plant's Unit 3, which authorities have been frantically trying to cool following a system failure in the wake of a massive earthquake and tsunami, triggered an order for hundreds of people to stay indoors, said Chief Cabinet Secretary Yukio Edano. Tokyo Electric Power Co. said radiation levels at Unit 3 were 10.65 microsieverts, significantly under the 500 microsieverts at which a nuclear operator must file a report to the government.
The blast follows a similar explosion Saturday that took place at the plant's Unit 1, which injured four workers and caused mass-evacuations. More than 180,000 people have evacuated the area in recent days, and up to 160 may have been exposed to radiation. BallDroppings. BallDroppings. aM laboratory. Treasures. Nudge. Qwiki. Login. Qwiki.
