CR-39 solid track detector is widely used in radon measurement because of its material stability and good practicability.In view of the high cost,maintenance cost and high environmental requirements of the existing commercial automatic reading system for solid track detectors,this study uses flatbed scanner equipment to carry out the study of solid track morphology,and establishes the radon track recognition rule based on track morphology parameters to achieve high efficiency and low cost radon measurement.The measured results show that the track density-exposure curve presents a good linear relationship when the radon exposure is below 500 kBq·h/m3.The research shows that the radon measurement method based on flatbed scanner is expected to achieve high efficiency measurement of radon,and the characteristics of this measurement method are high efficiency,low cost and strong environmental adaptability.
