Hi, Nice software, I've just started playing with it. I was looking at a PC MCA but was lucky enough to pick-up an Amptex MCA8000 and 3" scintillation probe...
It's a Gamma thing all the way around. Am-241 has a low energy Gamma, to which GM tubes over respond ( assuming they are thin enough wall for it to get inside...

Hi Seth, Have you ever taken a short cruise along River Road, in Apollo, Pa...about 30 miles N of the city? I missed the Babcox/Wilcox thread, but they had a...
Po 210 emits one photon just out of the range that over excites the LND 712 tube (.804 MeV). As someone else said a gamma scintillator will just pick up the...
Hey there! Yeah I live 3 miles from that dump site. They burried trucks, barrels etc. in that field. My spring break is next week so I will document readings...
-Chris, check the charts for the probability of that photon= .000011 not a strong contender! That is only .0011% chance of a hit. That's why I called it puny,...
Does any one know of any safety issues with these counters ? I recently used on and wonderered where these are from over 40 years ago could the unit itself be...
Thanks Geo, still learning to use the Decay Software, great stuff! to easy to click on the particle, need to look at probabilities too. I wasn't aware that...
With any Rad Equipment it is a good idea to check for radiation other than the check source if it has been used, since it may be or have been contaminated....
Absolutely! One list member recently received a contaminated probe from eBay. Be especially wary of alpha particles as contamination. Even though they are...
Chris, Where are you getting Baby Bens for $10? I've never paid over $3 for any of mine, and not over $4 for Big Bens, (except for a couple of genuine antique...
I am speaking in terms of eBay prices. I just got a GE Telechron at a thrift store for .42 cents (lots of radium and luminous material, not blazingly hot,...
If you're buying dark matter on eBay, insist on a flash photograph. Personally I prefer to collect cosmic background radiation. It takes up less space in my...

The question was asked "how does the pancake probe compare to the CDV-700's standard #6993 probe?". The quick answer is that a pancake is 5.5 times more...

The Na-22 makes positrons, the positrons turn around and make the annihilation X-Ray photons. Any time you see a 511.000 keV photons, they came that way...
