It is shown that the pyroelectric properties of tourmaline may be used for the measurement of large X-ray doses. The pyroelectric voltage across a specimen subjected to uniform heating between 300-600° K goes through a maximum which is dependent upon the previously received X-ray dose. This behavior is correlated with thermally stimulated current measurements. The sensitivity is low but the storage capacity high (~105R). At room temperature the energy stored does not decay measurably over periods of 2 weeks. Effects of neutron bombardment are also discussed.
