An integrated particle sampler and lung radiation dosimeter

A lung dosimeter that can record the nonradiological hazard of aerosol particles to the lung as well as the radiological hazard of air borne radionuclides that are attached to aerosol particles has been developed. The dosimeter is capable of recording aerosol particles of diameters from 10/sup -2/ /spl mu/m to 10/sup 2/ /spl mu/m by electrostatic collection in a specially designed dosimeter body. The aerosol size distribution is recorded on a mylar strip and the activity size distribution of /spl alpha/, /spl beta/, and /spl gamma/ radiation emitting aerosols are recorded on another strip coated with /spl alpha/-Al/sub 2/O/sub 3/:C. Both strips can be read by a specially built reader, the output of which can be used to calculate the nonradiological hazard and radiological hazard, respectively, and to give an overall picture of the exposure.
