Hello All,
I am playing with some questions in an old textbook I have been reading through and I am getting confused on this question regarding GM Tubes.The question that is stumping me goes like this:
If a certain GM Tube has a time constant of 80msecs and procedures require that count rate corrections be applied if more than 5% of the counts are lost, At what count rate per minute would count rate corrections need to start being applied?
I have read around in the book and can not find to much on the time constant. My idea is that I could do the following:
1min*(60s/1min)*(1/.08s)=750counts
750*.95=712.5counts
I just want to make sure that I am going about this the right way and not misleading myself here. Any help on this would be greatly appreciated.
Luke
