All Atomic.dave Geiger counters with pancakes are shipped inside Pelican atmospheric controlled cases. Also the GC design includes a gasket-spacer for reverse-bow window conditions. Even in the passenger compartment a Pancake detector (LND 7317, 7311, 7312, QPL 8767 et al.) is at risk. LND and Ludlum Measurements rate them only to 8000 feet altitude. Passenger compartments on commercial jets are supposed to be pressurized to 8000 feet equiv. http://www.ludlums.com/images/stories/news_letters/nwsltr-4re.pdf http://www.ludlums.com/images/stories/news_letters/NwsLtr-22re.pdf Because at this altitude the mica window on a regular pancake (gas fill is at less than 1 atm.) reverses its bow direction, from slightly inwards to slightly outwards, I designed my Geiger counters with a rubber gasket between the tube face and the stainless steel screen to accommodate this motion. Bill Lehnert of LND today verified: LND 7317-Routine operation at 5000-6000 feet no problem, i.e. Denver, Los Alamos. Above that they work fine until the reverse bow becomes a problem in the housing. Once the bow has reversed, the tube will continue to work fine. It is not a good idea to cycle between high altitude and low altitude, as eventually the seals will suffer. LND 712- the small 500V end-window used in so many pocket-sized portables will work at full vacuum. A great selection for Alpha Particle experiments inside a vacuum jig. Gamma sensitivity 18 CPS. LND 72344 (500V) or LND 72310 (900V) are actually described as end-window not pancake. To me they look like a small pancake. They are good somewhere between the 7311 and 712, so would be a very good candidate for a high altitude probe, still retaining a good Gamma Sensitivity number of 25. (End of Bill's contribution) It's really hard to beat a LND 7317 based geiger counter for general-purpose field work (60 CPS/mR/H Co-60). The transportation issue is a real one, so make arrangements for that. For routine high altitude usage, you might want to consider another type of tube. If you are not familiar with Atomic.dave Geiger Counters, they are based on a DIY kit designed by user Brohogan. It has certainly evolved over the past 3 years to have many more features, controls and options then it did back then. All info to create this kit is available on the website below so if you want you can create your own. The schematic and very detailed instructions are available at that site. This is more of a kit for someone who knows a bit about electronics but doesn't have the time or patience to build it. This is a hand crafted device and may have slight imperfection on them, but customers are all remarking about the excellent craftsmanship done on these meters. The components are all new, including the American Made GM tube, from LND, Inc. I will honor a 30 day money back guarantee if you are not satisfied with this item, however buyer must pay for shipping.
