80k Bq is around 2 uCi. That is coming from square meter. Testing I've done with 5 and 10 uCi point sources wouldn't really apply as they are such small amounts of material that falloff is rapid with distance. With a more even areal source I would think you'd see an increase in counts. GMC closer to ground, perhaps on the end of a wand (like a metal detector) might give good results. Just a thought.

Right, the best and easiest way to feel the ground is to operate the GMC on a Selfiestick for Smartphones. With the screen in large font, it is a very cheap and efficient solution to get good results. The most important thing is to use the GMC500+ in landscape mode with buttons on the right and the M4011 counter tube on the bottom.
Thanks for your thoughts ! I‘ll give it a try with my seflie stick, The gmc-500 fits very well with the holder of the stick- Great solution:) @geo-johnny im located in Vienna. just corrected my nick in gmcmaps.. where are you from?
