摘要

We described a method for long-term passive measurements of unattached fraction f_p of the potential alpha energy concentration of radon progeny from a set of measured (f₁, f₂, f₃) values, where f_i=C_i/C₀ (i=1, 2, 3), and C₀, C₁, C₂ and C₃ were the concentrations of ²²²Rn, and the airborne concentrations of ²¹⁸Po, ²¹⁴Pb and ²¹⁴Bi, respectively. Jacobi room model parameters were randomly sampled from their lognormal distributions to search for (f₁鈥? f₂鈥? f₃鈥? sufficiently close to (f₁, f₂, f₃) and to determine f_p. There was 99%and 88%chance obtaining an estimated f_p value within 50%and 30%of the true value, respectively.
