Abstract
Samples have been collected from different layers in a sedimentary phosphat ic deposit and sieved. Different granulometric fractions have been selected . The uranium and thorium contents have been determined in each phosphate s ample and its corresponding selected fractions. Radon (Rn-222) alpha-activi ties per unit volume have been evaluated inside and outside each phosphate sample and its corresponding selected fractions by using CR-39 and LR-115 t ype II solid state nuclear track detectors (SSNTD). The radon emanation coe fficient in each phosphate layer has been determined and the global radon a lpha activity outside a parallelepipedic block of the layers studied was ev aluated. The influence of the lithology and granulation on the radon emanat ion has been studied.
