Establishing Mathematical Models to Estimate the Activities of Radionuclides (R_a) and the Lung Cancer (Lc) by Using Some Numerical Method

摘要

In this paper, six mathematical models are constructed to estimate the calculated value of the activities of radionuclides (R_a). The estimations of (Ra) are conducted by relying on the uranium (u), while the value of the lung cancer (L_c) in the year10~6 pers. (L_c) is done by basing on the activity concentration of radon in Bq.m~(-3) (CR_n), and the value of the (L_c) is basing on the absorption effective dose equivalent (AE). These calculations are carried out relying on some numerical analysis method such as; Neville's and least squares methods. The obtained results were similar to the previous studies as well as the error rates were very few and almost nonexistent.
