Abstract
In this study, data from the first measurement of 236U in surface soil samples in Cameroon are reported, with the primary objective of establishing baseline data in the case of the accidental release of nuclear fuel to the environment in the future. For the first time in Cameroon, atom ratios of 236U/238U were determined, which ranged from 2.31 × 10− 8 to 4.95 × 10− 8. Furthermore, secular equilibrium between 238U and 226Ra in the sampled soils was studied, activity ratios of 226Ra/238U were out of unity. The 137 C activity concentrations occur as traces, ranging from below 0.1 to 6.7 Bq kg− 1. [ABSTRACT FROM AUTHOR]
