Re: Tritium and plastic

Well, taking the LD 50/30 as approximately 450 rem (Whole Body Acute 
Dose -- probably reasonable with THO with an effective 1/2 life of 
about 10 days):

ALI (Oral; THO) = 80 mCi = 5 rem 

LD 50/30 ~7 Ci (single intake)

I'd actually guess LD 50/30 will be a bit higher, but I'll leave that 
to someone who has any specific knowledge (or finds I fouled up my 
math).
