In order to obtain activity per unit weight of active particles

only, correction must be made for the per cent of inactive particles

{in the semple.

The values for per cent active particles (by volume)

obtained from the autoradtogreptis are listed in Table 4.1 along with

Data on Kac4
are not included because Na@ samples were containated
with BaluO, When it was learned that the shot device contained sodium
_tracer, it did not appear worthwhile to undertake the task of resolving
the decay curves.
