Phenomenon of low energy emissions from hydrogen/deuterium loaded palladium

Palladium loaded with either hydrogen or deuterium is found to give a clear autoradiograph on exposure to X-ray film. The phenomena is found to be 100% reproducible and is independent of the technique of loading, be it electrolytic, gas loading, plasma discharge or ion implantation. It appears only if the exposure to X-ray film is done in atmosphere of hydrogen, oxygen or air. These emissions are also detected by TLD measurements. Investigations seeking to identify the nature/energy of the radiation through transmission measurements using various filters tentatively indicate that the radiations could be low energy electrons having an energy of around 300 to 400 ev.
