I think you need to read some physics books. Gamma rays have smaller wavelength then X-Rays and visible light. And a re more powerful and hazards.

Gamma rays may have a subjective definition.You can say that Gamma Rays are photons emitted by state transitions of the nucleus and X-Rays are photons that comes from electrons. X-Ray machines emits what would be otherwise consider gamma rays, around 140KeV. For example, http://en.wikipedia.org/wiki/Technetium-99m The gamma ray can have a small wavelength such that it could almost fit in the range of visible light, such as http://en.wikipedia.org/wiki/Isotopes_of_thorium#Thorium-229m If you consider a gamma ray as photons originated by decays of excited decays of the nucleus, you can have wave lengths near the visible spectrum, 2011/10/29 Peter Heckert <peter.heck...@arcor.de> Am 29.10.2011 16:32, schrieb Jed Rothwell: Mattia Rizzi <mattia.ri...@gmail.com> wrote: How can rossi had a permit if inside the nuclear site there isn’t even a SINGLE “Nuclear Warning” panel? I don't know. I have not seen his application or permit. You have a good point. It might be prudent to set up some signs. I am not sure where you would put them, or how far away people should stay. Bianchini set up detectors and found nothing, so they did pay some attention to this issue. Still, as far as anyone knows, cold fusion never generates dangerous radiation. In contradiction to this, Rossi says the heat is made from soft gamma rays. Some 100 kW of gamma rays are dangerous. So it is a little silly to apply the safety standards of fission or plasma fusion to it. This is like saying that hydrogen airships can explode, so we should take extreme precautions when working with helium balloons. No it is like saying a helium Zeppelin is dangerous, because the inventor says, it is filled with hydrogen ;-) - Jed
