Abstract

The scrap metal waste export activity has proliferated in Benin and in the West African sub-region in recent decades. It is a sector that employs a growing number of workers, particularly on the Ex SONICOG site in the first district of Cotonou in Benin. Unfortunately, this scrap metal waste can constitute chronic sources of radioactive contamination of the soil and of exposure of populations to ionizing radiation. The objective of this research work is to estimate the specific activities of the soil and the radionuclides involved on the site of the former SONICOG scrap metals, which has been in operation for more than two decades. The methodological approach consisted in taking soil samples using the diagonal method and analyzing them by gamma spectrometry using a Baltitic Scientific Instrument, Ltd (BSI) type device fitted with Gamma Pro analysis software. . The results show a stronger contamination of the superficial horizons by radionuclides such as lead 212Pb, thorium 232Th, cesium 137Cs in general and compared to the control soil. On the other hand, potassium (40K) is detected only in the surface horizon of the soil1 while actinium 228Ac was found in the first two surface horizons of the soil2; as for americium (241Am), it has been detected in the soil3 but it is not quantifiable (low concentrations). Moreover, all these radioelements are in low quantity in the control sample (sol0) chosen as the reference soil. This observation, coupled with an unequal distribution of radioactive sources in the soil horizons, confirms the hypothesis that the radioactive sources come from ferrous and non-ferrous metals from scrap metal waste on the various sites. Workers in the scrap metal sorting-recycling chain risk the effects of direct chronic exposure to low doses of ionizing radiation emitted by these sources and populations from indirect exposure.
