Note: Trad is the total radon exposure. ${\hat{β}}_{S R S}$ : the estimator obtained by simple random sampling; ${\hat{β}}_{G C C}$ : the estimator obtained by generalized Case-Cohort sampling; ${\hat{β}}_{O D S}$ : the estimator obtained by ODS sampling. The three methods base on the same size of the sample.
