Abstract::
      The paper describes the method for determining 2tOpo in soil by volatilizafion.After being converted to chloride.Polonium in sample is volatilized by heating at 500°C in a simple volatilization apparatus and the vapourof polonium iscollected on glass fibre.Finally,210Po is separated by depositing it spontaneously on a silver disc.The experiments about the effects of volatilization temperature,time and etc.On the determination of 210Po have been carried out.The analyses of 210Po in soil showed that the results obtained by using volatilization method were consistent with that of the leaching methed.
