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 (UNSCEAR) [] points …

This study was carried out to evaluate activity concentrations of naturally occurring radioactive materials (NORMs) to assess the distribution of 226Ra, 232Th, and 40K 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. Twenty five (25) quarry samples were …
In order to assess the risk, a granite industry with a quarry and processing factory was selected to assess the occupational exposure. Three main potential pathways were observed: external irradiation, inhalation of granite dust, and radon exposure.
quantities to the atmosphere of the work environment. This dust particle have very harmful effect on the health of workers of quarry industries, that is why a decision to carry out a research on the effect of stone crushing dust on the health of workers of quarry industry at Umuoghara, Ezza North Local Government Area of Ebonyi State is inevitable.

A survey study on natural radioactivity of 238 U, 232 Th and 40 K and their possible radiological effects in the granite rock of selected quarry sites in Johor state, Malaysia has been carried out by using the γ-ray spectroscopy technique.
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 …
The rock fragments are further processed at the processing mill (situated near the quarry) into different sizes. Non-nuclear mining and milling industries have the potential of causing radiological problem . Hence, this work aims at assessing occupational radiation exposure due to NORM in the granite quarry industry. MATERIALS AND METHODS

Through the Hard Target Initiative, the quarry industry has achieved a significant reduction in accidents, and it is now time to pay equal attention to the management of health risks.
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 …
Although this industry is not considered as major industry in Kelantan the amount and elemental contents of dust that came from the industry warrant a valid concern for the quarry workers and public users of the products. These elements would pose radiological, pollution as well as health risks to workers, public and the environment.
