Radon/thoron detection properties of a CR-39 plastic track detector
Abstract
We have performed a series of experiments in order to develop a personnel dosimeter, employing a plastic track detector and having a high sensitivity for the detection of alpha particles emitted in the decay of radon and thoron gases. The paper describes our work on a new type of plastic track detector known as CR-39. This new type of detector has been calibrated and the optimum operating conditions have been established for its use as a radon/thoron dosimeter. The results obtained so far strongly suggest that CR-39 is not only the most sensitive track detector existing today for the detection of alpha particles from radon and thoron, but that it also has some unique properties which make it an ideal track detector for radon/thoron measurements.
