UV radiation is effective on all microbial forms in water but lethal doses for every particular taxonomic group may be considerably different. Three species of Penicillium, Aspergillus and Cladosporium genera, 2 species of Alternaria and Fusarium and 1 species of Rhizopus and Paecilomyces genera were tested. Model waters were inoculated with spores of the mentioned monocultures. Three heterocul...

Background: Ionizing radiation induces the production of reactive oxygen species (ROS), which play an important causative role in cell death. Wholebody exposure of mice to gamma radiation leads to diminution of tissue antioxidant defense systems increases the peroxidative damage to membrane lipids and damages the haematopoietic and gastrointestinal systems. Tempol (TPL), a cell membranep...

Enhanced cellular DNA repair efficiency and suppression of genomic instability have been proposed as mechanisms underlying radio-adaptive responses following low-dose radiation exposures. We previously showed that low-dose γ irradiation does not generate radio-adaptation by lowering radiation-induced cytogenetic damage in mouse spleen. Since radiation may exert tissue-specific effects, we exten...

Background: Ionizing radiation induces the production of reactive oxygen species (ROS), which play an important causative role in cell death. The aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from Auricularia auricular (SNAAP). Materials and Methods: Whole blood samples from healthy donors treated with SNAAP at differen...

  Today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “NUCLEAR” can induce worries in patients and society. In this article, base on new documents, we intend to show that this worries has no scientific basis. To produce a realistic view, ...

Background: Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. Materials and Methods:...

X-ray imaging in diagnostic radiology is recognized worldwide as an outstanding tool for the early recognition and prevention of diseases. The reverse side is that radiography contributes essentially to the exposure of the public. Mean effective doses, averaged over patients and non-patients, are reaching or exceeding the level of natural radiation. This is particularly the case when digital im...

The 1986 April 26th Chernobyl event was the worst nuclear power accident--it killed 31 people. Its significance was exaggerated immensely because of the pervasive fear of ionizing radiation that has been indoctrinated in all of humanity. In reality, our environment includes radiation from natural sources, varying widely in intensity, to which all living things have adapted. The effect of radiat...
