[ RadSafe ] C-14 in Teeth

[Flanigan, Floyd]

I presume the C-14 levels were weighed against the naturally occurring C-14 level known to exist in all living things?

I wonder what the delta turned out to be between the two.

Radsafers,

We all know about Sr-90 in teeth (Tooth Fairy controversy) and C-14 in wood
(radiocarbon dating), but here is a new one on me.

Atmospheric C-14 from nuclear weapons testing (1955 thru 1968) got into
tooth enamel and the C-14 concentration in teeth can be used to determine
the birth year of a person. It only works on people born after 1943.

Did anyone else know about this?
