摘要:
The high-precision measurement of Rn-220 is essential for assessing and preventing thoron radiological hazards. Prior research has revealed that employing a scintillation cell without a clapboard improves the detection efficiency for both Rn-222 and Rn-220 by reducing air pressure, and the Rn-220 calibration factor is established at an atmospheric pressure of 0.4. However, the decrease in air pressure leads to a corresponding reduction in Rn-220 concentrations within the scintillation cell, resulting in lower counts and larger statistical fluct...
