A total of 403 quarry workers, includ-ing men and women aged between 10 and 60 years were entered the study. They were then grouped into four groups, de-pending on the number of years each worker had spent working in the quarry industry (i.e., the duration of exposure to the quarry dust): group 1 had <5 years of
Workers in the granite industry face an occupational hazard: silicosis due to the crystalline silica present in inhalable dust. As granite can also present a variable, and occasionally significant, content of naturally occurring radionuclides, they may also face a radiological hazard. In order to as …

By using gamma spectrometry (NaI (Tl) 3" x 3"), the concentrations of (226Ra, 232Th and 40K) were measured and its radiological hazards were presented in this paper for some building raw materials (sand, clay and limestone) collected from the quarries of Assiut cement company, Assiut, Egypt.
The presence of naturally occurring radionuclides in construction materials originating from quarry products offers radiation exposure both inside and outside the …
1. Introduction. Soils and rocks are the main sources of terrestrial radiation since volcanic structures as well as rocks that are rich in phosphate, granite and salt contain natural radionuclides like 238 U, 232 Th and 40 K, which are the main sources of gamma radiation. In its report the United Nation Scientific Committee on Effects of Radiation …
The radiological effects on human due to the natural radiations from sand were also estimated by use of radiological parameters. The measured mean activity concentration levels of 238U, 232Th and 40K were found to be 94.93 Bqkg-1, 88.40 Bqkg-1 and 1763.79 Bqkg-1 respectively. ... (NORM) from soil samples around Gbose quarry of …

This study has found 32.5% prevalence of respiratory morbidity In stone quarry workers, on the basis of radiological appearance. ... In order to assess the effect of silicosis on lung function, 61 ...
This study tried to identify the environmental effects of quarrying in the identified quarry sites of Region 1 chosen at random, specifically at a geologic perspective. It further tried to discover the socio-economic benefits they provided to the residents of adjacent and nearby barangays within the provinces of locos Sur, Ilocos Norte, La …
The radiological impact of quarry activities on workers and local residents due to the presence of naturally occurring radionuclides have been investigated for two quarry industries.
The values obtained from this study are well below recommended standards. These results agree with the findings of Osahon and Abiola (2014) in their assessment of background gamma radiation within ...
The radiological impact of quarry activities on workers and local residents due to the presence of naturally occurring radionuclides have been investigated for two quarry industries.
The radioactivity of 40 K, 232 Th, 235 U, and 238 U in the examined samples were detected by passive gamma ray spectroscopy. The outcomes are displayed in Table 2 and Table S1. As shown in the Table 2, 40 K, 232 Th, and 238 U are detected in all the samples; the 238 U concentration is the highest concentration in all samples, it is ranged …
