GMC 500+ change Tube to LND 7317 Testing

Video shows how to testing a different tube on GMC-500+.

Very interesting. I was curious about modding a 500+ to work with a tube that also detects alpha, so this is super helpful.

well done more like this.... interesting

NOTICE: From the LND_7317 data specs - """"Recommended operating voltage (volts) 500, Operating voltage range (volts) 475 - 675"""".... I believe that your operating the LND at the MAX voltage will NOT do it any good.... READ THE SPECS before you cook a 125 dollar tube... Just say'in....

What is the conversion ratio on the LND 7317 tube from CPM to uSv do you how ?

[@KarbineKyle]

The _conversion ratio_ for the *LND 7317* is _334 CPM/μSv/hr (Cs-137)._ Or, _3340 CPM/mR/hr (Cs-137)._ Or, its inverse is _0.002994012,_ for _μSv/hr,_ _0.000299401,_ for _mR/hr._ This ratio is based off of the *_SEI Inspector USB_* and *_Ranger USB Radiation Alert_* Geiger-Müller counter series. These are excellent instruments by the way!
