counts to be expected from any given radon concentrationin the air.
Extensive examples of atmospheric measurements are given which suggest that under most conditions in the free atmosphere radon és essentially at secular equilibrium with its daughter products.
Other collections made following addition of radon to a restricted volume show the expected increase in p with time, which confirms the hasic validity of the procedure,
