Solar flares, really? Read again.

So what does that mean? > THE MINI GEIGER HAD HIT THE TOP OF THE SCALE Was the Geiger counter in unexperienced hands? No. What was Celardi's interpretation? This: > This meant that a SHORT BUT INTENSE EMISSION OF GAMMA RADIATION had So, no solar flares, dentists, welding apparatus, etc. Why did this happen? I assume this was because it was a prototype with partial shielding. Or maybe the reaction was pushed into an unsafe zone, or... time will tell! > An multiply observed fact is: No Gamma above environment are > measured with Rossis's e-cat during operation. Right, that's because the aim of the e-Cats is not to produce radiation, but to produce heat. As the engineering advances, shielding gets better, the reaction is better controlled, so there is less and less radiation escaping. > None is measured with 50 ecats in operation. Same answer. > Even if screened, a little bit must come through and must be measureable. No, it depends on thickness and flux. Photons below < 200 keV are easy to completely shield. See previous discussions. > So there is no high energy radiation inside. If by high energy you mean on the order of MeVs, you may be right about that. But there might very well be low energy radiation. Also, there might still be high-enery radiation since the physics of the device are not understood -- how about that heavy electron shielding? -- Berke Durak
