I agrees with John. In addition, the amount of Cs-137 in deer meat will
depend on where the deer were "harvested" from. When I ran the bioassay labs
at AECL/CRNL I noticed the highest Cs-137 in hunters that had been "up
North", particularly in the Hudson's Bay area.
My choice for a "marker radionuclides" to estimate dietary intakes would
always be Cs-137 (easy to measure gamma) over Ca-45 (low energy beta
emitter) or Sr-90 (low energy beta emitter with the high energy Y-90 beta
emitting progeny).

My comment regarding Cs-137 was to the idea that they
are looking a Ca-45 in baby teeth. Obviously this
plays into the concerns people have about childhood
cancers. However, it you examine the distribution of
Cs-137, which is also a long-lived component of
fallout and nuclear reactions. It is ubiquitous. It
is found in deer meat, in the soil, etc., in trace
amounts just like Sr-90.
Of course, environmental sampling does not have the
emotional impact of baby teeth.
