Re: Tritium consumer sources

John,

There are many devices over the years which were manufactured with tritium
as an illumination component after radium was no longer used.

Compasses with 50 to 500 millicuries on parts of the compass desired to
glow.

Aiming devices on military tanks to ensure alignment of the muzzle after
changes in temperature, 10 curies (99% gas) in glass enclosures.

Siting assemblies from mortar firing weapons, 10 milicuries to 100's of
millicuries.

Watches, 100 microcuries to 100 millicuries.

Rifle sights as low as 30 microcuries.

There are many more. - Exit signs are everywhere and typically contain 10 to
50 curies.
