 note = {Radiation doses associated with exposures to 222Rn (radon) and 220Rn (thoron) are primarily due to inhalation of their short-lived progeny instead of the gas. The dosimetric data of radon are commonly used to assess the risk of radon-induced lung cancer derived from epidemiological studies of underground miners and from residential pooled analyzes. For estimation of the lung dose due to radon and thoron progeny, the dose conversion factor, which is the ratio of the activity concentration or PAEC of the decay products and dose is needed. There are three commonly used internal dosimetric software RADEP, LUDEP, and IMBA, which can be competent to implement to most of the biokinetic and dosimetric models recommended by ICRP to deduce the dose conversion factor and moreover to estimate the lung dose. Although all of the three internal dosimetric software use the same dosimetric model recommended by ICRP, due to the different data handling techniques, there are minor differences between the estimation results of the internal dose. There were several researchers who used the RADEP and LUDEP to conduct the dose calculation of lung dose of radon and thoron, but fewer researches gave the effective dose coefficient especially on IMBA. In this research, therefore, the dose conversion factor based on IMBA was calculated based on the reference parameters provided by the ICRP 66 and 137 and was compared with the published value of RADEP and LUDEP.},
