Radioactivity And Dose Assessment Of Rock And Soil Samples From Homa Mountain, Homa Bay County, Kenya
The in situ measured average outdoor absorbed dose rate in air was found to vary from 108.4 to 1596.4 nGy h at Homa Mountain area in southwestern Kenya. Rock and soil samples collected gave average values of the radioactivity concentrations of K, Ra and Th of 915.6, 195.3 and 409.5 Bq kg, respectively. The range of the annual effective dose for a person living in Homa Mountain area calculated v...
متن کاملNatural radioactivity in rock samples of Aravali hills in India
Background: Natural radionuclides in rock samples, primarily 238U (uranium), 232Th (thorium) and 40K (potassium), are the main source of radiation exposure to workers and general public and their measurement is of paramount importance from radiation protection point of view. Materials and Methods: Gamma spectrometry using HPGe detector was used to measure the radioactivity and assess the radiol...
متن کاملContamination from Petroleum Products: Impact on Soil Seed Banks around an Oil Storage Facility in Ibadan, South-West Nigeria
The plants, grown in the soils around a Fuel Holding Depot of the Nigerian National Petroleum Corporation, Ibadan, Oyo state, Nigeria have been investigated in this research in terms of their density and species composition so that the impact of contamination by petroleum products on soil seed banks could be determined. The study has used designated plots (25m by 25m) in a site, contaminated by...

متن کاملPillar Design in the Hard Rock Mines of South Africa
This paper gives an overview of the difficulties associated with the design of hard rock pillars in South African mines. Recent examples of large scale pillar collapses in South Africa suggest that these were caused by weak partings which traversed the pillars. Currently two different methods are used to determine the strength of pillars, namely, empirical equations derived from back analyses o...
