On investigation, you are right. Tritium is both light and radioactive,
It also has a half life measured in days, so poses very little hazard.
12.something years, according to
www.epa.gov/radiation/radionuclides/tritium.htm and
others: 4500+/-8 days.
Perhaps I should have said more exactly that 'any radioactive element
with a sufficient half life to actually be present and represent a risk
to health will be very heavy'
Tritium only occurs naturally AFAICT on account of cosmic ray
bombardment. It decays as fast as it is produced.
This will be a different kind of tritium, then, from the stuff in the Traser
key-tags in my pockets, will it? Ummm...
site I looked up gave 4 days half life... Hmm.
