Increased sensitivity, decreased storage effect, and good dose- indication stability are provided by CaF/sub 2/. Mn dosimeters. The phosphor is coated on a graphite square, which is provided with electrical leads and sealed into an evacuated housing with a glass window. Dose determination is made in 30 sec by heating the graphite electrically and observing the glow with a photomultiplier tube. This design can detect 2.5 mr of Co/sup 60/ gamma radiation, and doses up to at least 10,000 r are measurable with the same device. The "pickup" of spurious glow has also been reduced by this arrangement. Stability of the dose indication is good, doses of 100 mr and 10 r both reading 90% of their initial value after overnight storage and then losing 1% per day for the next 12 days. (auth)
