Occupational Exposure of Well Logging Workers in Cameroon

In Cameroon, the growing demand for oil and gas exploration has increased the need for well logging services; however, the literature on occupational radiation exposure in this context remains scarce. This study aims to investigate radiation exposure among well logging workers in Cameroon. Monthly dosimetry data from 2020 to 2023 were analyzed for workers engaged in well logging. Results indicate that the highest collective effective dose is equal to 1.10 man. Sv was obtained in 2021, due to the fact that the most exposed worker received a whole body dose above 1mSv. None of the monitored workers has ever exceeded the investigation dose level, which is 2mSv. The average annual effective doses for monitored worker and measurably exposed workers during years 2020 to 2023 are below the limit value for the corresponding values of country like Algeria, Croatia, Czechia, Denmark, Myanmar, Slovakia, Spain, and United Arab Emirates, reported in the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 2020/2021 report (UNSCEAR, 2022). Although the study proved that the radiation exposure among well logging workers in Cameroon remains within international safety thresholds, it would be appropriate for operators to continue observing good practices, including implementing regular workers monitoring, bolstering training programs, and formalized and digitalized record management.
