The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation. These occur in varying combinations depending on the …
To assess the radiological impact of natural radioactivity of quarry activities in the study area, activity concentrations of natural radionuclides 238 U, 232 Th, 226 Ra and 40 K in the soil samples were investigated by collecting twenty composite soil samples from different sites of the area. Measurements were carried out using high purity ...
This Research involves qualitative, quantitative and radiological studies to assess the marl layer in the Euphrates Formation (Lower Miocene) as a raw material for Portland cement industry. The study area is located within the quarry of the Kufa Cement Plant in the Bahr Al- Najaf, which locates 26 km to the southwest of Al-Najaf city.

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.
This study was carried out to evaluate activity concentrations of naturally occurring radioactive materials (NORMs) to assess the distribution of 226 Ra, 232 Th, and 40 K in selected quarries in Edo State, South-south, Nigeria and to appraise the radiological hazard they may pose to the general public when used as building material. …
Guidance on the provision of barriers in quarries. The Health and Safety at Work etc. Act 1974 further requires that the employer (normally the Quarry Operator) makes sure that the conduct of his undertaking (operation of the quarry) does not expose those who are not his employees, but who might nevertheless be affected by the undertaking, to risks, so far as …

Torr Quarry has been active since the 1940s, covering 2.5 square kilometers near Shepton Mallet, with a current production of around 5 million tonnes of limestone, mostly used in road construction and transported by rail to the southeast. The quarry focuses on environmental sustainability, including creating wildlife-friendly lakes, landscaping ...

radiological risk to which an individual is exposed. Using an outdoor occupancy factor of 0.2 and the conversion factor of 0.7SvGy-1[9], the annual effective dose equivalent (AEDE) from the calculated outdoor terrestrial gamma radiation at 1m above the ground in the various quarry sites in Akamkpa in unit of mSvy-1 was obtained
Quarries dig stone from the ground, creating dust and exposing deeper, potentially more radioactive layers. Since the forest trails in the Park lead right up to …
However, research of radiological effects of a quarry on its surroundings is not common. ... Schaefer A, Wasum R. Mosses as indicators of atmospheric metal deposition in an industrial area of southern Brazil. Acta Bot Bras. 2012; 26:553–8. doi: 10.1590/S0102-33062012000300005. [Google Scholar]
Ionizing radiation has short-term and long-term effects on health particularly associated with the Naturally Occurring Radionuclides (NOR). The short-term effect should be prevented while the long-term effect should be reduced to an …
The results also revealed that a couple of the calculated radiological hazard parameters are higher than permissible limit, hence, such quarry products may pose a …
The mean value obtained for the various radiological indicators estimated for Johnson quarry are 1.03 x 10-3 µSv/hr, 1.81 µSv/y and 6.34 x 10-3 for exposure rate, annual effective dose ...
Human populations are being exposed to a wide spectrum of radiation from soils as a result of the availability of radiation sources. Assessing the ecological and health effects of radionuclides in soils is crucial to support the optimal soil management practices but large-scale studies are limited. This study compiled data on radionuclides (226Ra, …
