| Abstract: | A method of measuring mixed radon and thoron daughtersduring and after sampling is discussed and a versatile computer program foranalyzing observed data of radon and thoron daughters has been compiled onthe basis of mathematical methods of inverse matrix and weighted least squarescalculation.A set of optimum time intervals is recommendated for measuringthe concentrations of mixed radon and thoron daughters.Results show thatgreater accuracy of the concentrations of radon and thoron daughters is obtainedthrough the use of weighted least squares estimation procedure. |
