[ RadSafe ] Radioactive coffee? .....NORM ?

[Geo>K0FF]

Certainly it could be the K-40 from fertilizer, or perhaps uptake of Thorium 
from the Monazite, but a real
spectrum analysis would tell the tale. I'll be glad to do so free any 
charge.

Would anyone happen to know what NORM there might be in coffee beans, to 
increase their GM count rate to several times background ? .....such is the 
result obtained by a friend with various coffees, in different towns.


Could wood ash fertilizer be responsible ? (plant uptake or soil 
contamination of beans ?)
Or perhaps Brazil's Monazite ?

Thanks in advance.
