SYSTEM FOR DETERMINING THE RADIO-ACTIVITY OF GAS SOLS
Patent
·
OSTI ID:4773265
A system is designed for determining the radioactivity of aerosols above the natural background of radon and thoron. The system comprises means for collecting the aerosol particles on filter paper and alpha- and beta-counting detectors on either side of the filter, the beta detector having an absorbing filter for making the ratio between detected betas and detected alphas for the daughter products of thoron equal to that for the daughter products of radon.
