We use a nuclear technique based on the determination of detection efficiencies solid state track detectors CR-39 and LR-115 type II (SSNTDs) for alpha particles emitted from series uranium-238 thorium-232 in phytotherapeutic sample measurement densities registered these to assess activities due uranium-238; thorium-232; radon thoron samples preparations consumed by Moroccan adult patients. For...

The possibility to combine the track-etched CR-39 or Makrofol detectors with charcoal to increase the detector sensitivity was shown in the last years. Special requests are necessary in the case of a personal dosimeter when the detector must be active only during working activity. Regarding the combination of charcoal with TL detectors our preliminary investigations indicate that the TLD intens...

The report comprehends one decade experience in the use of the high radon absorption ability of bisphenol-A based polycarbonates for measuring radon. The three major directions of research and development include: (1) Use of the polycarbonate material, in particular that of which CDs/DVDs are made, as both radon absorber and track detector for measuring radon; (2) Use of a polycarbonate foil as...
