Radiation at Fukachima Daiichi NNP – March 27, 2011

Fukushima Daiichi Reactor units – readings near highly radioactive pools of water:

Unit 1:              60,ooo µSv/hr

Unit 2:       1,000,000 µSv/hr

Unit 3:           750,000 µSv/hr

See “Radiation dose levels, and some known effects” on the ‘Radiation Exposure Effects’ page to help put that in perspective.

Um… 1,000,000 µSv/hr  IS  ten millions times 0.1 µSv/hr, and the latter IS (or was) the normal background radiation of Coastal Japan, regardless of what isotopes the radiation is coming from.  Why do they say (see below) one thing to set the record straight with information which CONFIRMS that the media wasn’t exaggerating with the “10 million times normal” in the first place?   Sloppy.

SOURCE: http://www.world-nuclear-news.org“Contaminated pools to the drained – 27 March 2011-– Pools of water with significant contamination are slowing down repair work in units 1, 2 and 3 at Fukushima Daiichi. It was in unit 3 that three workers recently suffered burns.  The origin of the water remains unknown, but readings by Tokyo Electric Power Company (Tepco) have shown very significant radiation dose rates near the pools in the lower levels of the turbine buildings. In unit 2 doses from the water’s surface are 1000 millisieverts per hour, in unit 3 this is 750 millisieverts per hour while unit 1 shows 60 millisieverts per hour.”  … “Media coverage of the pools has been complicated by a mistake in Tepco’s reporting which put the level of radioactivity in the water at ‘ten million times’ the normal level for reactor coolant. The company has retracted this, explaining that the level it reported for iodine-134 was actually for another radionuclide with a longer half-life and therefore a lower activity rate.”
