Modeling the Controllable Parameters of Radon Environment System with Dose Sensitivity Analysis
Zoo, Oon-Pyo;Chang, Yi-Young;Kim, Kern-Joong;
This paper aimed to analyse dose sensitivity to the controllable parameters of indoor radon $(^{222}Rn)$ and its decay products (Rn-D) by applying the input~output linear system theory. Physical behaviors of $^{222}Rn;&;Rn-D$ were analyzed in terms of $(^{222}Rn)$ gas -generation, -migation and -infiltration to indoor environments, and the performance output-function, i. e. mean dose equivalent to Tracho-Bronchial (TB) lung region, was assessed to the following extented ranges of the controllable paramenters; a) the ventilation rate $constant({lambda}_v);:;0{sim}50[h^{-l}].;b)$ the attachment rate $constant({lambda}_a);:;0{sim}500[h^{-l}].;c)$ the unattached-deposition rate constant (${lambda}^u_d);:;0-50[h-l]$. A linear input-output model was reconstructed from the original models in literatures, as follows, which was modified into the matrices consisting of 111 nodal equations; a) indoor $^{222}Rn;&;Rn-D$ Behaviour; Jacobi-Porstendoerfer-Bruno model.
