Simulation of Best Condensation Radius of Radon Source Based on ANSYS in Absolute Measurement of Radon Activity

In order to simplify the multiple measurements of temperature field in the experiment of absolute measurement of radon activity, the heat transfer process and temperature field distribution were simulated based on ANSYS. Through the input temperature simulation, the best condensation radius of radon source in theory was determined. The result shows that the thermal analysis result has directive function in choosing input temperature.
