K-40 vs Cs-137 in soil

edit

Hi Jgaray,

I have rewritten the K-40 sub-section in a more NPOV state in the TORCH report. I think that it is vital that the reader should be made aware that the lower limit set for Cs-137 by the TORCH report authors is below the background levell due to potassium-40 in soil. I have included a reference to a soil which has been subjected to a lot of radiochemical examination this is the soil from the site of the first atom bomb test. The test would not have added any K-40 to the soil. Please if you have relative data for the transfer of potassium and cesium from soil to plants, and then to animals (and humans) I can then improve the article yet further.Cadmium
