Computation of Radiation Risk Parameters Due to Gamma Radiation Doses from Some Rivers within Oil Producing Communities of Abia State, Nigeria

Paschal Ikenna Enyinna & Gregory Onomakere Avwiri · Physical Science International Journal · 2016

Oil production involves the extraction of petroleum, gas and produced water, with some associated natural radionuclides from the sub-surface which could enhance background ionization radiation. This study presents the radiological analyses and computation of radiation risk parame...
