Attached is a recent experimental procedure and report that I performed to test out a simple boosting procedure on a low effieiciency, all glass, GM tube.

Richard:

I'm interested if you still had this file. I came from here viewtopic.php?f=13&t=5647&p=37875&hilit ... bes#p37875 and it seems like an interesting experiment.

I found a partial file from back then. There is enough to give you the gist of what I was doing. I will look to another CPU I have of that era. Apparently, I saved this partial file while working on the paper. the original was 365 kbytes.

Thank you Richard!
It was a most interesting read

The upshot, of course is that it is really tough to measure radiation from almost any source to some degree of precision without a lot of thought and good gear.
Likewise, you can boost the effective beta detection rate by placing a thin layer of the emitting substance on a thin lead plate over placing it on a piece of paper due to recoil.
You can do this for a cylinder magnet by backing one pole with a soft steel plate! The measured gauss strength can be increased at the non-backed pole over what would be measured with the same magnet, unbacked by steel. *Note this is not directly related to the radiation issue as completely different, unrelated mechanisms are at work.
