Research ArticleOpen accessPhrase in the titleDiffusion of Radioactive Materials in the AtmosphereAbdul-Wali Ajlouni, Manal Abdelsalam, Hussam Al-Rabai’ah, Abdullah M.S. AjlouniProblem statement: The dispersion of radioactive materials in the environment related to escaping of noble gases, halogens and aerosols of non-volatile radioactive materials, from the reactor containment during normal operations, or in the event of a sever reactor accident. Approach: radionuclide dispersion in the environment is demonstrated by mathematical tools which are the partial differential equations, mainly the diffusion equation. … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetermination of Absorbed and Effective Dose from Natural Background Radiation around a Nuclear Research FacilityMuhammad Auwal Musa, Idris Isa Funtua, Simon Peter Malam, Abdullahi Suleiman ArabiProblem statement: This study presents result of outdoor absorbed dose rate and estimated effective dose from the naturally occurring radionuclides 232Th and 238U series 40K, around a Nuclear Research Reactor at the Centre for Energy Research and Training (CERT), Zaria, Nigeria. Approach: A high-resolution in situ γ-ray spectrometry was used to carry out the study. CERT houses a 30Kw Research … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonstrous Hazards Produced by High Radioactivity Levels Around Assiut Thermal Power PlantHany El-Gamal, Mohamed El-Azab Farid, Abdulla Ibrahim Abdel Mageed et al.The natural radioactivity level of heavy oil, ash and soil samples around Assiut Thermal Power Plant (ATPP) in Egypt was determined using gamma ray spectrometry. The average concentrations of 226Ra, 232Th and 40K in fly ash were found to be 2307±143, 1281±80 and 1218±129 Bq kg-1, respectively, while the corresponding values in soil samples were 2670±107, 1401±78 and 1495±100 Bq … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 17 Sep 2013 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview on Studying 222Rn Exhalation Rates using Passive Technique Solid-State Nuclear Track DetectorsMohamed Abd-ElzaherProblem statement: Uranium is a radiotoxic element found in trace quantities in alomost all natural accurring materials like soil, rock. Radon an inert radioactive gas whose predecessor in uranium, is emitted from soil beneath the house and from building materials. Accurate knowledge of exhalation rate plays an important role in characterization of the radon source strength in some building materials … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 17 Aug 2012 · 8,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Radioactive Impact Associated to Uranium ProductionFernando P. CarvalhoProblem statement: One century of uranium mining in Europe and North-America created a legacy of ore mining and milling sites needing rehabilitation for environmental and human safety. In the last decades developments of uranium mining displaced the core of this activity to Australia, Canada and African countries. In the coming years, uranium mining is expected to grow further, in those … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 14 Jan 2012 · 8,249 accessesView PDFCite
