Cs has a high degree of similarity to potassium, chemically, as shown on the 
periodic table of elements. Therefore if it is in abundance in the soil, the 
plant will treat it as it would potassium, with the uptake in the same
ratio as K/Cs in the soil.

Stewart's Cs-137 in woodash report numbers make sense, since the prevailing 
winds in Nevada (NTS) are from the west.

An interesting report on the uptake mechanisms of soil Cs into plants can be 
found here:

*Specificity* in the human body similarly directs the uptake sites of 
certain similar chemicals and isotopes.
Radium is a calcium mimic for example, and radioiodines are thyroid specific 
because they are, well....iodine.
Na-22 and H3 are readily absorbed as well and should be handled with that in 
mind.
