Ten workers at Japan’s crippled Fukushima Daiichi nuclear plant were exposed to small amounts of radiation in cooling mist used to help the workers during a nasty heat wave in Japan.

Tokyo Electric Power company (TEPCO) said small amounts of radiation were found on the workers’ faces and hair. The workers were waiting for a bus when they were sprayed contaminated mist used to cool temperatures.  TEPCO doesn’t know how the mist became contaminated.  The mist was turned off and workers are told not to use tap water, which comes from the same source.

The workers were exposed above the neck and the dose was found to be as much as 10 becquerels per square centimeter.  They’ll undergo full body scans, which can detect exposure to their inner organs.

It’s the latest complication in two and a half years of complications.  Three Fukushima Daiichi rectors blew and melted through the floor after the 3/11 Earthquake and Tsunami disaster.  The plant is plaguing the surrounding area and Pacific Ocean with constant radiation releases and contaminated water leaks.

As for that heat wave, at least nine people are dead and the temperature reached 41 degrees in Shimanto, a city in Kochi prefecture on Shikoku Island.  About two thirds of the country is affected.
