Strontium 90 in ground water & Pacific Ocean

For the first time, Tokyo Electric Power Company says strontium 90 is contaminating ground water, and the Pacific Ocean.

Water samples that were taken on 16 and 18 May, 2011, are positive for strontium.  Sample testing takes three weeks for results.

Three ocean inlets were tested on 16 May.  The lowest reading was 53 times safe limits.  The highest, 240 times, was taken at reactor 3 inlet.

Ground water samples were taken on 18 May.  The highest reading was 6,300 becquerels per liter near reactor 2.

Strontium 90 is created during nuclear fission. It has a half life of 29 years and causes bone cancer.

Strontium 90 more widespread than first thought!

Japanese Science Ministry has finished a survey of Fukushima Prefecture.  They were looking for evidence of strontium 90, they found plenty.

Strontium 90 is created during nuclear fission.  It has a half life of 29 years, and can cause bone cancer.

Samples were taken at 11 locations, all 11 tested positive.  The furthest location from the damaged Fukushima Daiichi nuke plant, that tested positive, is Fukushima City at 60 km (37 miles) away.  The highest reading was 250 becquerels per kilogram, at Namie City.
