[en] In a previous paper we presented a method to analyze the data in a stacked film track detector and obtained a nuclear charge distribution for the incident heavy charged particles in cosmic rays. In the course of the analysis, several events of nuclear interaction were found. The present paper presents a method to analyze these interaction tracks by using the results of previous analysis for ordinary (non-interacting) tracks. (orig.)

[en] At present, different counting techniques can be used for the automatic scanning of damage tracks in solid dielectrics. This paper deals essentially with the experiences accumulated to-date on different types of spark replica counters. (author). 6 refs, 2 figs

[en] Bare Kodak LR-115 films have been used as detectors in the survey of radon in Finnish dwellings. The calibrations were made in a 8 m3 walk-in chamber under different equilibrium ratios and for very low equilibrium factors in a smaller 6 litre chamber. Within the experimental uncertainties, the results do not contradict the hypothesis that the efficiency of the film is the same for radon and its alpha active daughters. The radon gas calibration coefficient K was calculated for equilibrium factor F = 0.446 and was 20.0 Bq.m-3.d per tracks.cm-2. Errors in the method are discussed. Systematic errors due to the equilibrium ratio are calculated in three cases; radon gas measurements with bare films and alpha energy measurements with bare films and films in cups. (author)
