Why doesn cold fusion produce dangerous ionizing radiation and neutrons?
Nobody knows for certain why the primary signature of cold fusion is excess heat, not deadly radiation. Nevertheless, many LENR theorists have put forth very intriguing proposals for the mechanism of these reactions. There are, in fact, many dozens of competing theories—a smaller number of which are very well fleshed out. The exact nature of the LENR reactions is one of the many unsolved scientific mysteries surrounding them. Some scientists think that because the effect does not produce intense radiation, it cannot be a nuclear process. Others say the energy is produced, but then somehow absorbed by the metal lattice—either as high frequency vibrations, or through coherent processes in which many delocalized vibrations are involved. A potentially important point of confusion associated with the possible origin of this last kind of effect has been a failure by nuclear physicists to accept the idea (even though it actually is known to be present in conventional fusion) that longer range
Nobody knows! This is one of the many unsolved scientific mysteries of cold fusion. Some scientists think that because the effect does not produce intense radiation, it cannot be a nuclear process. (See the question above: “is cold fusion chemical, nuclear or something else?”) Others say the radiation is produced but then somehow absorbed by the metal lattice. In any case, it is a good thing cold fusion does not produce dangerous ionizing radiation because if it did, cold fusion cells would require elaborate shielding and cold fusion would be difficult, expensive and dangerous to commercialize. From the scientific perspective the lack of radiation and neutrons is puzzling and even annoying, but from the point of view of business, commercialization, and the environment it is a priceless advantage and a boon to mankind.
