An automated radon-thoron monitor for earthquake prediction research
Abstract
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.
