<abstract displayLabel="Summary">The method is an improvement of that of Ogden, and has the following advantages over other methods: the measurements do not require special samples, but can be made on ordinary airborne dust samples; the long sampling time is more suitable for stimating average exposure than the conventional short sample; radon and thoron working levels are both obtained; and the method is very sensitive. Side-by-side comparisons show good agreement with other methods</abstract>
