Abstract
The present invention relates to a device for monitoring alpha particles and material emitting alpha particles such as radon and its daughters. The device can also be used for monitoring other high energy particles such as cosmic rays, nuclear fission fragments, nucleon ions, and neutrons having energy between 0.1 and 200 MeV. In the operation of the invention, the high energy particles pass through and degrade tracks in a track registering material placed on a carrier substrate. These tracks are enlarged with a developing agent which etches the initial tracks. The enlarged tracks are then visualized by means of a color change in the immediate vicinity of these tracks.
