>From the experiments I've seen so far in my reading, there are two typtes of neutron emissions -- random and occasional bursts. Both are several orders of magnitude less than the tritium that is seen, which itself is far less than can account for heat. (Steven Jones and others took the specific step of omitting bursts of neutrons from consideration in a 1994 paper of theirs in which they were looking for neutrons, for reasons known only to them.) Typical count rates in earlier experiments are 1 n/hr to 1 n/s. I think there are higher rates as well. -- And, can contaminating radioactive isotopes be removed? > I assume this depends upon the set of claims. If neutron capture is going on, I think this would be made much harder, because of the activation. If proton (or alpha) capture is going on, the daughters are more likely to be stable, if the conclusion of an earlier thread here is to be trusted (I'm having trouble finding it). When I did a small investigation of transmutation results sometime back, I found that transmutations were generally to stable elements, apart from a handful of cases in which they were to radioisotopes. I get the impression that George Miley is a strong believer in this kind of possibility. Eric
