TL;DR: In this paper, the authors assess radiation risks due to natural radioactivity in samples of fly and bottom ashes collected from JLEC (Jorf Lasfar Energy Company) thermal power plant, and different analyses are performed through two nuclear techniques such as gamma spectrometry and alpha dosimetry based on the use of LR115 films detectors.

TL;DR: In this article, the specific activities of the radionuclides 226Ra, 232Th, 40K and the exhalation rates in terms of area and mass of 222Rn in some samples of building materials commonly used in Morocco in order to evaluate the radiological risk caused by natural radioactivity.

TL;DR: In this paper, the radiological impact of coal ashes, with enhanced natural radioactivity in the storage site of the JLEC-Morocco thermal power plant, is assessed by alpha dosimetry and a digital dosimeter on samples of coal ash, soil, atmospheric air, surface water and groundwater belonging to a perimeter of 10 km around that site.

TL;DR: In this paper, track detectors were exposed to samples of Moroccan phosphate and phosphogypsum to measure their α-particle radioactivity, and two formalisms were used for the dosimetry: simulation by a Monte Carlo method and determination of concentrations from a numerically integrated track registration equation.

TL;DR: In this article, a Monte-Carlo technique was applied to calculate the energy and angular-dependent α-particle registration probability of the solid state nuclear track detectors (SSNTD) CR-39 and LR-115 for members of the uranium and thorium radioactive families.
