Abstract :
The use of photoacoustic, piezoelectric, and pyroelectric radiation dosimeters is presented. New results with photoacoustic, pulsed photoacoustic, piezoelectric, and pyroelectric systems are discussed. The characteristics of the new dosimeters developed are compared. A theoretical model to explain the results obtained with the pulsed pyroelectric radiation dosimeter is presented and compared with experimental results. The use of such dosimeters as calorimeters for measuring energy fluence rate is also presented
