Probably some senators son died from tritium poisoning after a car wreck with a sign in the vehicle. Ya know, they could have listed cause of death as alcohol poisoning, but the tritium sign was right there...
Or weapons:
Because tritium is used in
boosted fission weapons and
thermonuclear weapons (though in quantities several thousand times larger than that in a keychain), consumer and safety devices containing tritium for use in the United States are subject to certain possession, resale, disposal, and use restrictions. In the US, devices such as self-luminous exit signs, gauges, wristwatches, etc. that contain small amounts of tritium are under the jurisdiction of the
Nuclear Regulatory Commission, and are subject to possession, distribution, and import and export regulations found in 10
CFR Parts, 30, 32, and 110. They are also subject to regulations for possession, use, and disposal in certain states. Luminous products containing more tritium than needed for a wristwatch are not widely available at retail outlets in the United States.[

They are readily sold and used in the UK and US. They are regulated in England and Wales by environmental health departments of local councils.[

becquerels per
gram (2.7×10−5
Ci/g) tritium and have a total activity of less than 1×109 becquerels (0.027 Ci), except for in safety devices where the limit is 74×109 becquerels (2.0 Ci) total activity.

Oddly enough, you can buy holders for the standard size in signs all day long on amazon, but no tritium itself to be had.
