Ratio of Sr-90 to Cs-137

Submitted by Anonymous on Wed, 2011-04-06 20:48

According to a expert at The Health Physics Society there is a certain ratio of Sr-90 to Cs-137 from Nuclear Tests. Here is the quote.

"The 137Cs deposition is not given, but you can estimate it by considering that cesium is produced by nuclear explosions in the ratio of about 1.6 times that of strontium. You can make the approximation that the depositions of the two radionuclides were also about in that ratio, primarily because their half-lives are so close to being equal."

Is there a way to approximate the ratio of Sr-90 to Cs-137 at Fukashima and the resulting fallout?

Were does the Strontium come

Were does the Strontium come from? Is there a rule of thumb like the example above that gives one an idea of How much Strontium was released at Fukashima?

Please anyone give info on

Please anyone give info on the Stontium-90 from Fukushima?
