| Summary: | and sensitivities of commercially available polycarbonate Both films responded to the typical alpha energy of radon and bright holes as seen with LR -1 15 11 film (using transmitted CAPFILM PC were simultaneously exposed in the radon exposure CAPFILM PC. The film was exposed first to alpha particles chamber which was connected to a barrel containing uranium chosen conditions and the calibration constant was determined determining the optimal etching conditions. The initial established as 0.03 tracks cm-2 kBq-1 h-1 M3 9 and, because etchant in comparison to LR-1 15 11. The optimal etching etching parameters for CAPFILM PC require a higher etching etching with 6.25 N NaOH for 3 hrs at 65 C. The chemical film, Kodak LR-1 15 II. The polycarbonate film used was for 145 minutes at 60 C (Vasudevan 1991). Both LR-1 15 and for each film. The calibration constant for CAPFILM PC was generated by a uranium foil to expedite the process of have a range from 1.03 to 2.16 tracks cm-2 kBq-1 h-1 m3. its daughters. The calibration constant for CAPFILM PC film Jim. The optimal condition for this thickness required light arrangement). of batch variation, the Kodak film's constant was measured to ore. The exposed film types were etched separately at their parameters for LR-1 15 11 were found to be with 2.5 N NaOH Research was performed to study the etching characteristics temperature, longer etching time, and higher concentration of thickness of CAPFILM PC chosen for characterization was 15 track detectors and to compare them to cellulose nitrate was determined by using a reflected light arrangement, in which the etched tracks appeared as black holes rather than |
