Interesting subject ! Uranium was the rage during the late ’50 thru the 1960’s Government paid people to go hounding for it Guess it ran its course now as a valuable commodity but rare earths are the next big thing! Friend of mine own this It’s a super scintillator 115 We keep talking about getting it operational all it needs is is a battery and know how to scant resources ha ha They’ve been used by aircraft to detect activity on the ground Made for locating uranium or thorium deposits, most of that is found in New Mexico, Nevada and Colorado with some in Canada. anyway good luck Ed

Not bad for a 50 something year old piece of equipment... good luck with the batteries. I've converted some old test equipment to other power supplies, but these things need pure D.C. for good readings. So now you just have to get an airplane that will do about 100 mph and not get shot down while your flying over White Sands, NM Dr Joe .

Funny that you mention that doc! cause we have single engine pedal glider around here, somewhere this place as everything my friend who own the scintillator tells me it will find dinosaurs and I'm like radioactive ones ! but she's a girl so I go along

Some of the Az pet.wd will make a geiger counter hit; rspecially the yellow wood. I didn't believe it till I tried, ( it at the urgeing of a college prof.) and , sure enough. not big but it's there.

That’s interesting about the pet wood Gary I suppose bones can be radioactive also I think my girl friend’s originally thought her scintillation :blush: till I told her I'm a ground penetrating radar There are tales of tunnels in this old area of Phoenix dug by none other then Jack Swilling that interests me! so those are all great devices along with the good old metal detector all rock hound would love to own Now that I've hi-jacked this thread I’m sure Scott doesn’t mind

There is a guy across from me here in Tucson selling cold war era radiation detectors for $20. I am tempted but doubt they would be sensitive enough for what I want. As mentioned some pet wood (especially from the areas I collect in in Utah) is hot. Especially the yellow and red. It would be fun to check it.

I have access to 2 of the old Geiger counters and they are pretty darn accurate. There is a place we dig pet wood with yellow the Geiger registers it well. The material was slab-able years ago and for some odd reason the ladies that wore it were getting sore on their chest so the Geiger counters were bought and guess what they were hot.w

There are several types of Geiger counters. Many of them are survey meters (think post blast) and don't have effective ranges for small doses. This is a great resource: www.civildefensemuseum.com/cdmuseum2/supply/radkits.htmlIn addition to power supplies, you also will be challenged with calibration. Chuck
