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 ...

The high level of anthropogenic pressure on agro-landscapes recently leads to an increased their contamination with heavy metals, which are among the most harmful chemical pollutants for environment. Heavy metals transmitted through trophic chains a pronounced cumulative effect, in connection toxicity can appear suddenly individual links chains. danger from is determined by fact that, unlike or...

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,...

Objectives : A water treatment system, combining aeration and reverse osmosis (RO) processes, was introduced to improve supply facilities in a small village where additional required due high concentrations of natural radioactive substances, nitrate nitrogen, fluoride. In this study, CCRO(Closed-circuit osmosis) first for commercial use Korea. With we evaluated its efficiency effectiveness blen...

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 ...

As a result of the nuclear accident in Fukushima Dai-ichi power plant, which started on March 11, 2011, radioactive pollutants were transferred by air masses to various regions of the Northern hemisphere, including Europe. Very low concentrations of (131)I, (137)Cs and (134)Cs in airborne particulate matter were measured in Athens, Greece during the period of March 24 to April 28, 2011. The max...

background: poorly educated people in some parts of iran use burned mantles as a wound healing medicine. materials and methods: to perform surface area measurement, twenty rats were divided randomly into two groups of 10 animals each. the first group received topical burned radioactive lantern mantle powder on the first to third days after making excision wounds. the second group received non-r...
