摘要
To accurately measure and evaluate the radiation dose of 220Rn and its progeny, a 220Rn chamber with an airflow model has been developed and studied, but it is difficult to take into consideration many relevant factors such as adsorption, wall attachment, and decay. This paper proposes the concept of cyclic loss rate of 220Rn progeny based on progeny supplement technology, establishes a theoretical formula to calculate the cyclic loss rate, and analyzes the relationship between cyclic loss rate, fan frequency, and aerosol particle size through both experiments and modelling methods. The feasibility of the cyclic loss rate model is experimentally verified.
