Radiometric and Geophysical Investigations on Exposure Levels and Excess Cancer Risk in Kargi-Kenya

Radiation is considered one of the possible causes cancer disease with natural background sources including cosmic, terrestrial and internal radiation. A number cases have been reported in Kargi their not properly documented. The present work characterized radioactivity soil water, to find out radiation KARGI-KENYA by studying magnetic intensities, anomalous zones depth delineating subsurface structures. total 117 14 water samples were collected from entire area analysed for radionuclides due 40K, 232Th 226Ra. Measurement methods proton magnetometer gamma spectrometry employing a high purity germanium (HPGe) detector employed basically evaluate survey radiological hazard radioactivities respectively. 51 field measurements taken on eastern part Kargi, place suspected more concentration radionuclides. results showed that there could fractionation during weathering period or metasomatic activity radioelements involvement. This study also reveals mining activities nearby affected geologic formation causing fracturing rocks pronounced structures as result served passage leachates pollutants well level area.
