Dr. Ndjana Nkoulou, Joseph Emmanuel | Radiation Protection and Dosimetry | Best Researcher Award

 Dr. Institute of Geological and Mining Research, Cameroon

I am currently a Research Officer at the Radiation Protection Laboratory, Research Centre of Nuclear Science and Technology (CRSTN) within the Institute of Geological and Mining Research (IRGM), Cameroon. This year, I defended my PhD thesis in Nuclear Physics, focusing on public exposure to natural radioactivity in Cameroonian homes. My work involves environmental radioactivity monitoring and public dose studies in mining areas, alongside various IAEA projects to mitigate radon levels. With over a decade of experience, I am eager to engage in new research opportunities in Nuclear Physics to further enhance radiation safety and public health.
