Assessment of human exposures to natural sources of radiation in Kenya
Mustapha, A.O; Patel, J.P; Rathore, I.V.S (1999)Exposures to various components of the natural background radiation in Kenya were estimated using measured activity concentrations of natural radionuclides and conversion factors. Contributions to the total effective dose ... -
Environmental Radiation Survey of the Area of High Natural Radioactivity of Mrima Hill of Kenya
Patel, J.P (Department of Physics, University of Nairobi, 1991)This report is on radiation contamination mapping of Mrima Hill in Kenya's south coast. A survey, covering the whole hill and the surrounding areas was carried out using a contamination meter. The gamma dose rate is extremely ... -
Modeling the 2-D seismic velocity structure across the Kenya rift
Braile, L.W; Wang, B; Daudt, C.R; Keller, G.R; Patel, J.P (Department of Earth and Atmospheric Sciences, Purdue University, USADepartment of Geological Sciences, University of Texas at El Paso, USADepartment of Physics, University of Nairobi, Kenya, 1994)A 460-km-long seismic refraction/wide-angle reflection profile across the East African rift in Kenya has been interpreted using a travel-time inversion method to calculate a two-dimensional crustal and uppermost mantle ... -
Natural Radioactivity in Some Building Materials in Kenya and the Contributions to the Indoor External Doses
Mustapha, A.O; Narayana, D.G.S; Patel, J.P; Otwoma, D (1997)Against a background of growing concern over the health risks associated with exposure to natural sources of radiation, a study has been carried out in Kenya in which the activity concentrations of the major radionuclides ... -
Palaeomagnetic results from late Archaean and early proterozoic granites from South Western Kenya
Patel, J.P (Department of Physics, University of Nairobi, 1989)Results of a palaeomagnetic study carried out on the Migori granites exposed in the South Western part of Kenya are presented. The granites of Post-Nyanzian and Post-Kavirondian ages are dated at View the MathML source, ... -
Paleomagnetic results from the Narosura and Magadi volcanics of Kenya
Patel, J.P; Raja, P.K.S (Department of Physics, University of Nairobi, 1979)Results of a paleomagnetic study carried out on the exposed volcanic rocks on the western side of the South Kenya Rift Valley are presented. Nine stratigraphic groups ranging in age from Miocene to Pleistocene were sampled. ... -
Results of optical, thermomagnetic and electron microprobe analyses of titanomagnetite grains
Patel, J.P; Palmer, H.C (Department of Physics, University of Nairobi, KenyaDepartment of Geophysics, University of Western Ontario, London, Canada, 1982)This paper presents results of a study of titanomagnetite from specimens of ten different rock units. The rock units comprise trachytes, basalts, ignimbrites, nephelinites, olivine melanephelinites and welded tuffs from ...
