“…As for the groundwater samples, they were analysed using the -spectrometer and the liquid scintillation counter utilizing gross alpha and gross beta methods. Sample results demonstrate increased levels of natural radioactivity that requires treatment procedures before the water can be used for human consumption as reported in [35].

Radiological characterization of the phosphate deposit in Al-Jalamid phosphate mining area, Saudi Arabia

It is a known fact that phosphate rocks have high levels of natural radioactivity due to the presence of large concentrations of radionuclides. This work aims to estimate radiation exposure and dose levels at Al-Jalamid site in northern Saudi Arabia. Al-Jalamid area is one of the largest reserves of phosphate worldwide. Ma’aden, a Saudi Government public company, owns the mine and is responsible for all mining activities. Phosphate and soil samples collected from Al-Jalamid phosphate mining area have been analysed for their uranium and thorium content by an α-spectrometer using radiochemical techniques. The quantity of radon gas was measured both in groundwater and in the atmosphere (indoor and outdoor) at the site using a portable radiation survey instrument. Groundwater samples collected from wells surrounding the mining area were analysed using a liquid scintillation counter in addition to an α-spectrometer. Finally, it is found that phosphate rock concentrate products cannot be utilized economically based on the standards set by the International Atomic Energy Agency (IAEA), since the average activity concentration does not reach the limit set by IAEA and hence are not commercially feasible.

“…The absorbed gamma dose rate (D) refers to the amount of radiation energy absorbed or deposited per unit mass of the substance. This radiological parameter is used to characterise the external primordial gamma radiation in the air at about 1 m above the surface of the ground, and it was calculated using equation (6) as proposed by (UNSCEAR, 2000) [36]. The annual effective dose equivalent (AEDE) in μSvy −1 resulting from the calculated absorbed dose values (D) was determined using equation (7), where O C represents the occupancy factor taken as 0.2 and conversion coefficient (F C ) of 0.7 is used to convert absorbed gamma dose rate (D) to AEDE.…”

“…The utmost significance of this area of geology is from the fact that rocks and minerals constitute fundamental building blocks of the planet, and as such, they contain several natural occurring chemical elements that are essential to plant, animals and human in considerable small doses. Hazardous contaminations of these elements in nature are also inimical to human health, since these elements are taken into human body through food, water and air [4], [5], [6], [7], [8]. Weathering of rocks form the soils on which crops and animals are raised.…”

AIM: This research presents the radiogenic components in thirteen limestone samples from a quarry site in Ewekoro, southwestern Nigeria. METHODS: The distributions of natural radionuclides (238U, 232Th and 40K) in the limestone samples were determined by gamma spectroscopy using a well-type thallium-doped sodium iodide detector. Also, estimated associated radiological hazards are presented and compared with the standard threshold values. RESULTS: The activity concentrations for 238U, 232Th and 40K radionuclides range 18.09 ± 3.43-239.50 ± 25.74 Bqkg-1, 8.33 ± 0.83 - 360.01 ± 21.33 Bqkg-1 and 11.28 ± 0.81-735.26 ± 0.95 Bqkg-1 respectively. The radium equivalent activity concentration in the samples ranges 58.857-758.832 Bqkg-1 with samples S3, S4 and S11 values higher than the threshold limit of 370 Bqkg-1. Estimated dose rate and annual effective dose rate (AEDE) from the samples have ranges 28.754-330.917 nGyh-1 and 35.26-405.84 μSvy−1 respectively greater than the standard limit of 59 nGyh-1 and 70 μSvy−1 respectively for all samples except S9. The estimated external and internal indices are ranging 0.16 – 2.05 and 0.21 – 2.68 respectively, greater than permissible unity in some limestone samples such as S3, S4, S8, S11 and S13. Excess lifetime cancer risk was also computed using a life expectancy of 54.5 years. The results of higher radiological parameters in the limestone samples revealed that the miners have a high probability of contracting induced cancer. CONCLUSION: A regular check-up is recommended for the miners and staffs within the quarry site. Also, the residents within the environs should be relocated far away from the quarry site, as the particulates from the limestone rock blasting could contaminate the air in the study area.
