Ever wonder what happens to the over 600 pounds of DU that an airplane uses for counterbalance and ballast after a crash? Here is one real life scenario: ...

It takes energy to create an ion pair from a neutral atom. Each time an ionization occurs, the radiation particle or photon loses energy at a rate of about...
Greetings group. I am creating a display of various CDV instruments for a local college. I have most models but am short a couple. I have numerous duplicates...
As with the CDV-700s, I am creating a CDV-710 display. I have - model 2 (Jordan) model 3 (Victoreen) model 4 (Jordan) model 5 (Victoreen) - with aluminum...
Continuing with display items, this time CDV-715: I have: model 1A (Landers, Frary, & Clark) model 1A (Lionel) model 1A (Victoreen) - standard faceplate model...
CDV-711: I have - model 2 (Nuclear Chicago) looking for - model 1 (I believe Nuclear Chicago) model Mark III (Nuclear Chicago) CDV-717: Have - model 1...

I've recently measured the inside surface of some air hose and found a moderately high alpha count (well, it's much higher than the outside). I assume that...
... If it hasn't lost any activity in a month, then the only radon daughter that I can think of that could be present would be Pb210 with a 22y half life. But...
What was the air hose connected to? Radon daughters should decay away very quickly. Was the air hose used within that month or was it just sitting there with...

Am working on a CDV700 probe. The Amphenol connector in the probe base had been twisted out and broken away from the cable. I've dug out the epoxy? which...
... Meant to reply sooner, but got busy. I don't have any data for the Ludlum Model 4, but they are a nice company to deal with, and they will send you a...
Geo; I counted five layers on the pallet (pic 1), each with four boxes of 10 units. But I was flat wrong, too- AT LEAST SOME of them are CDV-715s. And the ENI...
That's correct, each master box is 3 times as long as it is wide. sorry. I stack them that way myself in the basement, and had to go look to remember! 200...
Excellent guess, Chris. I'm actually trying to determine if the counts I'm measuring are due to an anti-static device upstream from the tubing. The source is...
If you want to "filter out" radon progeny you must use a filter with some rather fine holes. Such filters are not dirt cheap. What are the specifications of...
A fatal truck crash and fire about 20 miles down the road from my house on Nov 23rd 2004 killed the driver and burned up all the mail. Some of my orders were...
Hi all, I finally got around to having a play with my new DOM 410 GM meter. I must say that I'm very impressed. The basic unit (with internal tube) is fairly...
... Just to toss in my nickel; I would use a "charged media" type filter to remove the particulate daughters. At a reasonable flow rate these charged plastic...
Robert, I am glad you feel you got a good deal, I really like my Dom 410. It doesn't sound as though you got any of the check sources. One thing I have...
Hello, I am new on this forum and I am a beginning amateur. I own a GM counter ( FAG IM7001) which displays down to 0.01 uGy and has separate beta, beta+gamma...
