Abstract

The experimental work described in this paper was based on the Compton effect for the scattering of gamma radiation. For measurements one used a set of apparatus provided with a probe to measure density and a counter with a feeder from an accumulator. A 5 mc cesium isotop (Cs-137) was the source of radiation. The research comprised the calibration of probe, building of an experimental wall in a sheet iron, and systematic measurements during the humidification by electroosmosis. As a result of the experiments one obtained lists of relations between radiation intensity and time, moisture and time, and radiation intensity and moisture.
