Title Radon and thoron working levels from ordinary industrial-hygiene dust samples.
Bibliographic information July 1977, Vol.20, No.1, p.49-53. 4 ref.
Abstract The method is an improvement of that reported under CIS 75-1900. Its advantages are: measurements do not require special samples; the sampling time of >2h is highly suitable for estimating average exposure; radon and thoron working levels are both obtained; the method is highly sensitive (an 0.001 working level is easily measured). Theoretical considerations are appended.
