Yamali is exactly right.
You simply CANNOT shield this kind of gamma radiation well with lead. Some always escapes. There is essentially ZERO chance of selling this kind of reactor in the USA without NRC permit. EEC would be similar. From: Yamali Yamali > He has always said that there are gamma rays. He shields them with lead. There are no gamma rays leaving the device. This is all consistent. Actually no. It is impossible. You can't shield gamma rays completely. You could shield them enough to be so few that they would be undetectable. But if Rossi says he generates the heat by thermalizing them, then the e-cats don't have anywhere near enough mass to accomplish that. 1ev equals 1.6 × 10-19 joules. The supposedly 30 mm of lead would catch a little less than 99%. The devices generate about 10 kW. Rossi is alive. It just doesn't make any sense - unless... well... maybe thermalizing gamma is just a second job or doesn't happen at all.
