New methods and apparatus for the passive sampling of radon are introduced in the present paper. These samplers are based on the sorption of radon by layers of different types of solids. These solid layers result in sources of alpha, beta or gamma radiations, which can be detected by any passive or real-time detector, thus obtaining a variety of new radon monitors. By way of example, by facing one of said layers against a nuclear track detector, it is possible to obtain a compact radon film-badge. This film badge makes it finally possible to solve most of the shortcomings of existing passive monitors, based on track detectors, for the measurements of short- and long-term exposures of radon in air, in water, and in soils. These devices can be easily implemented by any existing radon service just as a back-up technology, with little or no change of the presently-used passive monitors.
