An integrating radon progeny monitor developed by the JNC Ningyo-toge collects radon progeny on a filter using a pump with a lead storage battery and detects alpha particles by a CR-39 detector. However, it differs from others in that it uses interval operation for sampling and that it has the function of estimating the effect of components attached by diffusion during the interval. The monitor makes possible the long-term measurements of radon progeny concentration over a month without an AC power source. The monitor is suitable for environmental monitoring. Several experimental measurements were carried out at laboratories and at outdoor fields. The measurement results by the integrating monitors have agreed well with our previous investigations.
