SSNTDs in the automatic detector of radon

The simple automatic detector with application solid state nuclear track detectors is described. The tape of LR-115 is reeled up on the cylinder connected with a clockwork. One revolution of the cylinder occurs for 2 weeks. All devices are in the pipe, which is dug in the soil. The special adaptation enables to exhibit the certain site of a tape during the chosen interval of time. Results of measurement of radon with the help of such a detector on the mud volcano and in the cave are shown. Good concurrence of the results received by different detectors is observed. The daily data from detectors, which simultaneously worked in the Krasnodar territory (Russia), were imposed on the map of region. It has been noticed, that areas of high concentration of soil radon move to that side where the earthquake occurs.
