I'm pretty sure that there are some good pictures of what nuclear explosions in space look like, considering that we detonated a number of Hydrogen bombs there...
Hi all, Recently picked up a CDV-700 6b Geiger Counter by Electro- Neutronics. I'm curious if anyone knows what the check source actually is? The book says...
For a couple pictures of the Starfish Prime 1.4 Mt detonation at 400 km, see http://www.geocities.com/CapitolHill/3589/starfish.html In "near space" it looks...
Seems there's a little confusion here. The AEC created the film, showing how their personnel responded and did exposure control and PPE. If you saw it, you'd...
The Project Argus atomic blasts were all radially symmeterical in form. I haven't been able to figure out why Riddly Scott made the nuke blasts go horizontally...

I have a vague feeling I've seen a NASA photo that had the flat shockwave, I'm thinking perhit might have been a nova in progress, where the star is orbited by...
I recently joined your club as I am facinated by geiger counters and radioactivity. I have an "as is" CDV-700 model 6A by Victoreen. It is quite accurate, but...
Hi Peter! Welcome aboard! Sorry to take so long to approve you... Been a circus here as of late. Congrats on the '6B! Sorry to hear about the meter. That can...

Hey guys, Just read in an old "modern marvels" book from 1955 about an "atomic battery". Basically, it seemed to be similar to a photocell, except the source...
Gentlemen of the Group: I have some very interesting questions. Are there any of you familiar with a MK 15 Mod 1Thermonuclear Bomb? I refer to the one lost...

Paul, I remember the "atomic battery" from when it was mentioned in a "what's new" article in a hobbiest electronics magazine in the 50s. I remember it as a...

Question on a Scuba 700, What depth would your probe or geiger counter need to go to, I was assuming between 50 and 200 feet. A glass or Aluminum tube with...
