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.
