ABSTRACT:
A radioactive light source consists of a vacuum tight envelope filled with a mixture of a radioactive gas such as tritium with one or more other gases which luminesce when excited by the emission from the radioactive gas without the aid or requirement of any externally applied energy source, such as electrical power. This luminescence may be viewed through the wall of the chamber which may be transparent. Alternatively, all or a part of the luminescence may be converted to a different region of the spectrum by a suitable phosphor layer coated on the wall of the envelope.
