In reply to Esa Ruoho's message of Tue, 29 Mar 2011 20:38:48 +0300: Hi, First, "radiation" doesn't necessarily imply "radioactivity". The former can just be instantaneous radiation, as in e.g. x-rays. The latter implies radioactive substances which have a half-life and emit ever less radiation until they have finally decayed completely. So it's possible that Rossi's device produces radiation but no radioactivity, IOW after you turn it off it may only contain stable isotopes that are not radioactive. This needs to be properly studied.
Even for radioactive substances, the half-life (the amount of time it takes for half of the substance to decay), varies enormously, from a tiny fraction of second for some to longer than the age of the universe for others. Substances with a very short half-life emit all their radiation in a short period of time, so you don't have to wait long for them to become harmless. Those with longer half-lives are the main concern, particularly those elements which naturally concentrate in the human body, where they can cause cancer. Examples of these are radioactive Cesium and Iodine, which is why these substances keep being mentioned in regard to the Fukushima disaster. Even if the nuclear process(es) actually involved in Rossi's device turn out not to be completely clean, they are at least thousands (if not millions) of times cleaner than normal fission reactors. Furthermore, if nothing else, the device is worthy of study because it may lead to even cleaner means of producing energy. It could also lead to a method of converting the radioactive waste already produced by existing fission reactors into stable isotopes, so that it doesn't need to be stored for millions of years. That's because fission reactions create isotopes that are "neutron rich", which may be especially susceptible to proton fusion, resulting in stable isotopes. >-- > >?"Does this system produce any radioactivity? >Yes, but it is all contained inside of the reactor vessel which is shielded >by two centimeters of lead.
