Wo know that

If we express the activity in the animals, instead
of in terzs of tetal body burden, but rathor in terms of strontiun per gram of bone, we cone across a fisure something like
this (cholh denonstration).
There are these conversion factors.
You can soo that <7 is not much in tems of a nicrocurie,
which is sonowhore around the body burders pornissible of hunans,
