RE: "Tritium on Ice"
Mr. Arland is correct in that the US NRC has the sole authority to approve
of products containing byproduct radioactive material for distribution to
persons exempt from licensing. They do have a clause in their regulations
stating that 'frivolous use' items that will not be approved. So novelty
items or products that work equally well without radioactive material might
have a hard time passing acceptance unless there is a demonstrated benefit
for the risks posed by the product. Tritium labeled gun sites are the best
example I can think of where the line has been drawn in that a nominal
quantity of H-3 has been allowed to be distributed in aids to weapon owners
(largely the US Army). I suspect there are gray areas on either side of
that line that may or may not get approval
The thoughts expressed are mine, mine, all mine....

In answer to your question about U.S. vs Europe limits. I can't give you a
reliable answer to your question. I believe that the NRC approves consumer
products
on an "item by item" basis which includes dose, risk, etc., which could well
rule
out a single item unless it had been put through the process. The NCRP
Handbook
95, on Consumer Products, Chapter 3.1 has a lot of information on
radioluminous
products. The ICRP publication 60, "1990 Recommendations of the
International
Commission on Radiological Protection" gives some general information on the
"International" view on allowable doses etc. for comparison with U.S.
limits.
A couple of other references on tritium that might be of interest are;
Proceedings of "European Seminar on the Risks From Tritium Exposure", 1982
held
by the Commission of the European Communities. The report information is -
EUR 9065
en, 1982
The 400 page book "Tritium-labelled Molecules in Biology and Medicine" by
Feinendegen, Academic Press, 1967 gives a lot of excellent basic
information.
Sorry I can't be of more help.
