Abstract:
LR115 track detectors were exposed to samples of Moroccan phosphate and phosphogypsum to measure their -particle radioactivity. Then two formalisms were used for the dosimetry: simulation by a Monte Carlo method and determination of concentrations from a numerically integrated track registration equation. The results were compared with those deduced γ-ray spectrometry.
