Japan recently announced plans to discharge over 1.2 million tons of radioactive water from the Fukushima Daiichi Nuclear Power Plant (FDNPP) into Pacific Ocean. The contaminated can poses a threat marine ecosystems and human health. To estimate impact plan, here, we developed three-dimensional global model track transport dispersion tritium released FDNPP. pollution scenarios for four release ...

Abstract The accidents at nuclear power plants pose a particular threat to the population and environment. Accidental emissions can cause long-term radioactive pollution of environment, elimination such take years. For practice, it is very important predict intensity size contamination zones for various scenarios extreme situations plants. Such forecast will identify most vulnerable areas devel...

Nuclear energy has significantly promoted the development of human society. However, nuclear pollution caused by accidents can lead to significant hazards environment and health. As a major radioactive product, iodine (mainly existing as I−) detection attracted attentions. In this study, zirconium(IV) is used enhance oxidation environmental I− form I2. Subsequently, generated I2 oxidizes chemic...

T he last century has witnessed the fastest population growth in human history, with the result that, for the first time, more than 50% of the world population lives in cities. This process is still advancing. According to United Nations predictions, urban population will exceed 75% of the world’s population by 2070. Furthermore, estimates are that if the current trends continue, by the end of ...

background : the aim of the current study was to develop a marking technique as an internal marker to mark post blood meal mosquitoes by using stable phosphate isotope 32 p and determine the optimal concentration of it. methods : an isotonic physiological saline solution, containing different concentration of radioactive isotope 32 p-labeled disodium phosphate (na 2 h 32 po4) was injected into ...

in the recent years, interstitial brachytherapy implantation has become the treatment of choice for early stage prostate cancer patients. treatment of prostate cancer with radiation is traced back to 1909. originally this treatment modality was very crude and could not gain much popularity till 1982. advancements in radioactive source designs, introduction of new low energy radioactive sources,...

1. NATIONAL FRAMEWORK FOR MANAGEMENT AND REGULATION OF RADIOACTIVE WASTE AND DECOMMISSIONING 1.1 National framework 1.1.1 Overview of national policy The Atomic Energy Commission (AEC) of the Korean government developed the “National Radioactive Waste Management Policy” at the 249 th meeting held on September 30, 1998. The policy stipulates that the site selection process for radioactive waste ...

In order to ensure the long-term effective isolation of radionuclides from human beings environment, pyrite and magnetite, which exist widely stably in geological can be considered reduce strong mobility high-valence redox-sensitive nuclides low-valence with low mobility. this work, reducing reaction between pyrite, (U, Se, Tc, Np) Gansu proposed-treatment plant area was under simulation by PHR...
