- Abstract
The continuously discriminative monitoring of radon and thoron is a significant project in the realm of radiation protection, which can provide statistical supports for the accurate estimation of internal exposure dose in radon thoron hybrid environment. Using the improved ZnS scintillation cells and based on the delay count method (DCM), an experimental device for radon-thoron continuous monitoring has been devised. This device has been tested under both laboratorial and on-site conditions, the measurement results from this device were compared with that from Alpha Guard DF2000 result, the deviations of the measurement values of this device and Alpha Guard DF2000 are less than 10% for both radon and thoron even when the radioactive concentrations of radon and thoron differ drastically (the ratio is over 1 30), besides, the disturbance from the previous sampling durations up on the long-term monitoring values has been eliminated. To conclusion, this device is capable to discriminate radon and thoron accurately under distinctively different concentrations of radon and thoron.
