A true bronchial dosimeter has been designed, consisting of four 400-mesh wire screens and a filter paper. With a face velocity of 3.3 cm s for home exposure and 4.6 cm s for mine exposure, the deposition pattern on the wire screens were found to satisfactorily match the variation of the dose conversion factor (in units of mSv WL M) with the size of radon progeny from 1 to 1000 nm. In this way, the bronchial dosimeter directly gives bronchial dose from the alpha counts recorded on the wire… CONTINUE READING
