Radiological Dose Implications of The Natural Radioactivity In Surface Soils In Ekiti State, Nigeria
I. R. Ajayi
KEYWORDS: Environmental, radioactivity, radiation, soil dose
ABSTRACT:The radiological dose implications of the natural radioactivity in tha surface soil across Ekiti State, Nigeria have been determined in this study by using a very sensitive gamma spectroscopic system of measurement Effective dose at 1.0m above the ground in the State was found to vary between 0.037 and 0.227mSv while the fifty years integral dose obtained ranged from 1.85 to 11.5mSv with a mean of 5.4770+ 2.926mSv. The estimated average effective dose equivalent for the State is 0.109±. 0.058 mSv. This value is far below the 0.41 mSvy-1 estimated as the world average by UNSCEAR and the dose limit of 1.0 mSv per year recommended as the individual dose limit for members of the public by the International Commission for Radiological Protection (ICRP).
