title: Spicer: a sensitive radiation survey instrument.
abstract: A compact, portable field instrument for measuring environmental gamma-ray exposure rates has been developed. Based on an 18 cm diameter pressurized ionization chamber, a temperature compensated MOFSET electrometer and a digital readout with selectable integration times, it is a considerable improvement over previously used larger and bulkier instruments of this type.
