Hi, Curious on the resistors: In the old days, items marked with "M" were designated for the Latin "M" meaning thousand... Wonder if those resistors were...
... were designated for the Latin "M" meaning thousand... Wonder if those resistors were really 100k and 500k Ohms, respectively instead of meg Ohms? Oh my....
Yes, I've seen that old practice of designating 1000 by M. My impression is that it was mainly used in commerce, rather than science and technology, but I...
Confusing, but M would mean 1000 resistors in the box, M means Mega- (as in Ohm), Methadone, Molar, but MBH meas thousands of British Thermal Uniuts-Mil means...

Brian, Sounds like you acquired an interesting peice of equipment. With my limited experience it sounds as though you may have a gamma scintillator. Many ...

In my opinion, the pacake is superior for these reasons: A)works with any 900V Geiger Counter with no modifications needed ( scintillators need special Voltage...
