Has anyone dragged an He3 neutron detector to the Project Faultless SGZ Site?

<r>1 Megaton underground thermonuclear explosion, might be a interesting place to prospect for neutrons??<br/> <br/> <URL url="http://www.wikimapia.org/1508709/Project-Faultless-Ground-Zero-CNTA"><LINK_TEXT text="http://www.wikimapia.org/1508709/Projec ... -Zero-CNTA">http://www.wikimapia.org/150870...

<t>Dan DT wrote "511 Kev emission? That is the rest energy of a positron, but when it annihilates, it does so with an electron. Wouldn't this create a 1022 KeV photon?"<br/> <br/> <br/> There are of course two 511 photons, one in is in opposite direction so we can't see them both.<br/> <br/> In PET-...

Has anyone tried to monitor the 511 keV annihilation line from Sun Fusion?

<t><br/> <br/> If it can be detected at the earth's surface, it might be interesting to chart the normal vs. solar flare levels. As we head into another solar max, might be a good project idea.<br/> <br/> The Sun works by the Proton Chain Fusion Reaction. In a variety of steps, 4 protons get fused i...

Re: Group Buy of BTI Bubble Dosimeters

no, they don't even advertise them, evidently it is an experimental model, but I can vouch that they work. George Dowell

Re: Group Buy of BTI Bubble Dosimeters

PS they have gamma bubbler detectors too. I have (had) one.

Re: Group Buy of BTI Bubble Dosimeters

Mine is shot totally. Full of large bubs, won't reset any more!

I want a new one, but funding is an issue unless the order is a month or so off.
