We describe an automated instrument for earthquake prediction research which monitors the emission of radon and thoron from rock. The instrument employs (1) aerosol filtration techniques and β counting to determine radon and thoron levels; (2) a programmable microcomputer which controls mechanical operations, collects data, and monitors the condition of key components; and (3) a call-up telemetry system for the transmission of data to a central location over standard telephone lines. Data from the field operation of the instrument is presented. © 1978.
