The advantages of the enclosure method are outlined for registering β + γ doses in relation with the quartz inclusion method. However, the need for quartz-like dosimeters is pointed out: discrepancies up to 25% of the γ dose relative to quartz can occur if using CaSO4or CaF2dosimeters. An attempt is presented here with Al2O3dosimeters embedded in low-activity well-known powdered rocks and put back in the sampling location for several months. Subtraction of the α contribution is achieved from α counting on the rock samples. Calibration, accuracy and further developments are discussed. © 1988.
