[Method for the determination of alpha radiation potential energy of radon decay products occurring as free ions].
The paper presents a simple method of measuring the concentration of alpha radiation potential energy of radon decay products occurring as free ions in the air. This method consists in deposition of free ions of radon decay products on the surface of metal plates in so called impactor, which is constructed by an appropriate selection of shapes and mutual arrangement of the plates. The paper presents an improved system of calibration of impactor, which continuously produces free ions in the tube, through which the filtered air containing radon is being passed. The least concentration of alpha radiation potential energy of radon decay products free ions, detactable by this method, when 1 liter of air is passed through the impactor, is 10(3) MeV liter-1). This method may be applied in laboratory and environmental measurements.
