[ RadSafe ] BNL tritium, etc.

[William Lipton]

Isotopic specific activities are listed in DOT - PHMSA regulations, at 49
CFR 173.435.  For tritium, the listed specific activity is 9.7 E3 Ci/g.  6
MCi leads to 619 g, close enough for government work.  Your other
calculations check out.

It's not about dose, it's about trust.
