BETHE:
factors of safety or wicertainty which you bring in by first calculating
one thing and then another and forgetting what you have calculated before,
and that is way I would like to caleulate a uniform distribution and then
ask what is the ratio of this to total caleium, and this ratio to total
ecaleium should be all right even if we heve a nosunifora distribution.
BGLOMON:
But {£ you consider the ratio of strontium to caleius there are three
sets of figures that are available I think.
One is that Comar finds
that anisals take up strontium at the came rate that they take up
ealctum.
This is ens set of figures.
Secondly, there is a set of
figures in the literature sbout a couple of other investigators in
which it looks as if animals take up caleisum twice as rapidly as they
take up strontius.
fector.
In other words, there is a tvo-te-one competition
Thirdly, there ia the data the Krieger has which based upon
just the distribution of the normal strontium to caleium ratio in matter
as it now exists, there is «a faetor of 100 between the sofl and san.
BETHE:
In whieh direction?
ERIEGER:
Soil has a higher ratio of strontiua to calcium.
BETHE:
What ratio do you get for soil?
KRIEGER:
The typical Eastern American soil is the ratio af about 35 strontium atoms
to a 1,000 caleim= atoms.
In the results of inveatigators at UCLA, the
ratio for adults, that is from 3 years up to 72 years, te about ¢.5.
The
7 is on the weight basie rather than atomic.
