Experimental Study on Gathering Gas Device and Collecting Gas Condition of Rn-Content Observation in Fault Soil Gases
This paper has done the experiment on different observation device and collecting conditions. The results indicated that, the gathering chamber detention volume has affect to observe result greatly, but the dead volume not. Therefore, the gathering chamber effective size should not retain the detention volume. This experimental result has provided the scientific basis to formulate the observation technology standards of Rn-content in the fault soil gas.
