refer to the full steady state condition and are obviously
at least as nearly in equilibrium with the environment as
the fallout radioactive strontium ever will be.
These data
are presented in Figure 2.
The occurrence of radium in the
human body also has been used since it is chemically similar
to both calcium and strontium, and therefore is a bone
seeker and because it is obviously also in steady state
equilibrium. The data used were those by Palmer and Queen3/

And, finally, we use the recent data on occur-
rence of normal potassium in human bodies as determined by

as presented in Figure Lh. All of these data show a normal
frequency distribution as indicated by the theoretical curves.
The respective widths of the curves (standard deviations) are
36 percent for radiostrontiun, 40 percent for normal strontium,
LO percent for radium and 18 percent for natural radiopotassiun.
It is completely clear from these data that they agree with
