Tea leaf farmers don't accept dried leaf analysis

Excessive levels of radioactive cesium was detected in the tea leaves.  Main of the tea leaf growing area is lying to the west of Tokyo, opposite side to Fukushima. As the area is farther from Fukushima than Tokyo, some people looked to be shocked. (A lot of farm products grown in the area between Fukushima and Tokyo are sold because their analysis showed under levels)
One of the most shocked people are tea leaf farmer.
Monitored tea leaves are raw. Government told dried leaves should be monitored too.
But tea leaf farmers don't accept dried leaf tea analysis.
When making dried leaves,  leaves lose their moisture but they don' lose radioactive things. So it is very clear that analysis of dried leaf will show higher radioactive than raw leaf.
They insist boiled up tea will show lower level than guideline.
