Assessment of Radiation Hazard from External and Internal Exposures at Adham and Surroundings in KSA
Twenty-eight environmental samples (eight well water, sixteen granitic rocks and four soils) were collected from different parts of Adham governorate (Adham, Haqal Al-Jaizah), to assess the radiological hazard cancer risk perspectives. is situated in a valley between two mountain chains, where much water supply for drinking, house use irrigation comes wells collecting rains. The activity concen...
this research aims to study the relationship between the components of quality costs and quality in company. the relationship between the components of quality costs and quality in company has been studied separately for materials, manpower, machinery, and whole of company. in this study, traditional method was used to collect quality costs and paf model was used to determine the components of ...
Background: Natural radiation is constantly present in the environment and is emitted from a variety of natural and artificial sources. It affects human body and environment. Materials and Methods: The activity concentrations of 238U, 232Th and 40K have been determined by Gamma ray spectrometer with an HPGe detector in sediments of Cauvery River, Tamilnadu, India. Results: The absorbe...
Introduction: Considering the risk of radiation, the measurement of the natural radiation sources seems to be necessary. In this study, the concentrations of the natural radionuclides, namely 226Ra, 232Th, and 40K, were measured in the soil samples taken from different locations of Golestan, Iran. The measurement results can also be used as a baseline to evaluate the impact of non-nuclear activ...
A study on natural radioactivity in virgin and agricultural soil samples collected from Sungai Petani was conducted using high-purity germanium. The mean activity concentrations of 226Ra, 232Th, and 40K in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 Bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 Bq kg−1, respectively. The co...
background: natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. so, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. materials and methods: ...

This work deals with the measurement of radioactivity concentrations from different cement samples collected South Gondar Zone, Ethiopia. The naturally occurring radioisotopes and radiation health impact indices caused by these nuclides in are indisputable dwellings. Specifically, average for 226 Ra, 232 Th 40 K were estimated as 76.53, 81.67, 407 Bq kg −1 , respectively. It was seen that all m...
This study was conducted to determine the radioactivity concentration in soil samples of Anarak-Khour district located at central Iran. 48 soil samples from a depth of 10-15 cm were taken from seven different sites for monitoring. The radioactivity concentration of 238U, 232Th, 137Cs and 40K in soil samples was determined, using a high resolution (HPGe detector, p-type) γ-spectrometry by detect...
introduction: cleaner productions in textile industry is achieved by reducing water and chemicals’ consumption, saving energy, reducing production of air pollution and solid wastes, reducing toxicity and noise pollution through many solutions. the purpose of the present research was to apply strengths, weaknesses, opportunities, threats (swot) and quality systems planning matrix (qspm) techniqu...
