Continuous measurement of equilibrium equivalent radon/thoron concentration using time-integrated flow-mode grab sampler

The continuous measurement of any physical entity is the finest approach to see the real-time variation of any concentration. In the present study, an effort has been made to see the continuous variation of radon and thoron progeny concentration (EERC and EETC) using time-integrated flow-mode sampler in which the deposition of progeny particles has been done in the filter paper in which an absorber has been mounted which specifically absorbs the alpha energies emitted by the progenies of radon or thoron. Also, the variation of thoron progeny concentration (EETC) using two different types of SSNTDs, LR-115 and CR-39, has been seen and it has been found that the measurement of EETC using both of the detectors is very much comparable with positive relationship (R = 0.89) between the results obtained.
