en Assessment of Ambient Ionizing Radiation Dose Rates and Radiological Risks in Selected Municipal Dumpsites of Akwa Ibom State, Nigeria Air and waste management Original articles <div style="text-align: justify;">Introduction: Over the years, some municipal dumpsites have been found to exhibit ionizing radiation due to indiscriminate dumping of hazardous refuse. Materials and Methods: An ionizing radiation survey of five municipal dumpsites in Akwa Ibom State was conducted to measure elevated radiation levels. The five dumpsites were Uyo Village Road, Nung Udoe, Nwaniba Road, Abak Road, and Udo Street. Radiation exposure at each dumpsite was measured using a Digilert 200 radiation survey meter. Results: For the Uyo Village Road dumpsite, the mean Absorbed Dose Rate (D), mean Annual Effective Dose Rate (AEDR), and mean Excess Lifetime Cancer Rate (ELCR) were 8.2 x 10-5 nGy/hr, 0.10 mSv/yr, and 0.35 x 10-3 respectively. For the Nung Udoe dumpsite, the mean D, AEDR, and ELCR were 1.0 x 10-4 nGy/hr, 0.12 mSv/yr, and 0.43 x 10-3 respectively. For the Nwaniba Road dumpsite, the mean D, AEDR, and ELCR were 9.9 x 10-5 nGy/hr, 0.12 mSv/yr, and 0.43 x 10-3 respectively. For the Abak Road dumpsite, the mean D, AEDR, and ELCR were 8.9 x 10-5 nGy/hr, 0.11 mSv/yr, and 0.38 x 10-3 respectively. For the Udo Street dumpsite, the mean D, AEDR, and ELCR were 8.2 x 10-5 nGy/hr, 0.10 mSv/yr, and 0.35 x 10-3 respectively. The mean Ds and AEDRs were far below the world average limit of 59 nGy/hr and 1 mSv/yr for the public, respectively. Conclusion: The reported values do not have any immediate radiological health hazards; however, residents and workers should reduce the hours spent at the dumpsites.</div> Assessment, Ionizing, Dumpsites, Radiological Risk, Absorbed Dose. 3008 3021 http://jehsd.ssu.ac.ir/browse.php?a_code=A-10-1100-1&slc_lang=en&sid=1 Dianabasi Nkereuwem Akpan dianabasiakpan@uniuyo.edu.ng 0009-0009-3188-2353 Yes University of Uyo, Uyo, Akwa Ibom State, Nigeria Akanimo Dianabasi Akpan akanimoekanem@aksu.edu.ng 0000-0001-7065-6898 No Akwa Ibom State University, Ikot Akpaden, Mkpat Enin, Nigeria Sunday Samuel Ekpo sundayekpo@uniuyo.edu.ng 0000-0002-9361-7186 No University of Uyo, Uyo, Akwa Ibom State, Nigeria Michael Ephraim Edem michaelephraimedem@gmail.com 0009-0000-4065-1965 No University of Uyo, Uyo, Akwa Ibom State, Nigeria
