Don't be surprised at strange readings for the next few days I am testing a new counter and location etc. Running on a backup right now, different tube position, will probably give a lower count. This counter is an RHElectronics one.

Still an SBM20.

Well that idea didn't work, back to the drawing board.

Are your readings still a bit too high? I've noticed your background seems to be around 35-45 cpm. That's nearly twice what I get with the same tube.

My problem is the location, which is a semi-basement built of xisto, the local micaceous schist. The whole area is heavily mineralised with lead, tungsten, silver and uranium having been mined in the past. I believe the high counts are due to radon. My previous location in West London gave much lower counts. The radiological map for Europe suggest that background can be up to 10 times that in London. My current project is working towards an exterior probe.
