MULTI-INTERVAL COUNTING FOR MEASURING RADON DAUGHTERS

Zhang Zhe;Wu Guibui;Wu Feng(The Uranium Mining Research Institute)  
When concentration of radon daughters in atmosphere ismeasured,measurement error can be decrease by means of increasing countinginterval.Optimization procedure of measurement condition for more than 3multi-counting intervals has been adopted and the best sampling period,nu-mber of counting interval,measuring period and dividing inteval have beendeveloped.Results of multi-interval counting were compared with Thomasmethod through experiments.
