Five types of alpha track detectors (ATD) have been studied in determining the sensitivity for detecting radon and radon decay products in equilibrium with radon in indoor air measurements. The ATDs were films of LR{sup -1} 15 type I and type II, CR-39, Patras and CN-85. The best chemical etching conditions of these solid state nuclear track detectors (SSNTD) have also been examined. From all of the ATDs examined it was found that CR-39 detectors had the highest sensitivity as high as 0.3 tracks cm{sup -2} kBq{sup -1} m{sup 3} h{sup -1} for measuring equilibrium equivalent radon (EER) concentrations. No correlation existed between the sensitivity and the exposure time of ATDs.
