In conclusion - there is no doubt that if we believe anything about the Rossi reactor of today based on demos - they produce no gamma radiation. The HotCat, which is by far the most robust LENR reactor every documented - is unshielded. No lead jacket, no gamma. I followed you up to here. There is no possibility of any prime reaction - if that reaction is producing quanta over about 2 keV. But this seems an unwarranted inference. Not well worded on my part, Eric. Apologies. The inference is based on the lower limits of detection with a tritium detector and the chances of higher energy being reported. Photons below 2 keV could avoid detection. But above – they would have been seen. Rossi has allies in ENEA - and apparently wants to eventually proceed to home use. They have the tritium monitors. Plus, he would be concerned about the health effects for his employees, so it is not a big leap to suggest the HotCat has been tested over the entire spectrum and he thinks that an unshielded reactor is safe for himself and his staff.
