Hi,
Yes, teeth can be used as a dosimeter (and have...). TLD is one method, but has some problems.
Another is the use of a technique called ESR, using the eletron spin of long lived free radicals
left in the enamal as dose dependent monitors. And then there is a in situ method that has been
developed using photo luminesence.
Anyway, a good document search in medline or other journal indexes will give you plenty of
references. At our home page is a link to Barry Pass in Canada who has done some work in this area.

and look under dosimetry.
