摘要：
Our paper presents two methods for simultaneous measurement of radon and thoron exhalation from soil and building materials: (1) charcoal adsorption, (2) Lucas cell methods. Both methods are applicable especially in the case of a soil flux enhanced in thoron gas. In the Lucas cell case, a short accumulation time was used (10-15 minutes). The thoron concentration in the accumulation volume was measured immediately after the sample gas extraction and a regression equation is used for determining equilibrium thoron concentration. In the case of the charcoal method the thoron was measured 4 hours after a special degassing of the sample. Using the LUK-3A device for the building materials, the thoron flux was measured only on a special enhanced thorium + radium sample.
