Background: Turkey, especially the northern part of it, was one of the countries which were contaminated by the Chernobyl accident.  Rize is a city located in the Northeastern district of Turkey which was heavily influenced by the Chernobyl nuclear accident. Materials and Methods: In this study, the activity concentrations of natural (226Ra, 232Th, 40K) and artificial (137Cs) were measurem...

The actual and next decade will be characterized by an exponential increase in the Beyond Low Earth Orbit space exploration. In this context, a detailed radiation field characterization crucial to optimize radioprotection strategies, assess risk of health hazard related human exploration, reduce damages potentially induced astronauts from galactic cosmic radiation. Since beginning century, many...

background: turkey, especially the northern part of it, was one of the countries which were contaminated by the chernobyl accident.  rize is a city located in the northeastern district of turkey which was heavily influenced by the chernobyl nuclear accident. materials and methods: in this study, the activity concentrations of natural (226ra, 232th, 40k) and artificial (137cs) were measurements ...

The proximate cause of cancer cell death by radiation therapy and a number of therapeutic agents is through generation of reactive oxygen species, resulting in DNA damage as well as mitochondrial membrane disruption, triggering the apoptotic cascade. Because mitochondrial manganese superoxide dismutase catalyzes conversion of superoxide radicals to H(2)O(2), with catalase neutralizing H(2)O(2) ...

Introduction: The present study investigated the relatively high concentrations of natural radionuclides in raw material that used in ceramic manufacturing, and estimated the occupational exposure due to these activity concentrations. Material and Methods: A high-purity Germanium detector was used to determine naturally occurring radionuclide...

The natural (40K) and anthropogenic (137Cs) radioactivity concentration in four different typologies of early childhood (up to two years old) foods, i.e., homogenized fruit, meat, biscuits baby pasta, produced Italy sold Italian large retailers, was investigated through High Purity Germanium (HPGe) gamma spectrometry. present study is carried out with the aim to: (i) evaluate background levels ...

Twenty-eight environmental samples (eight well water, sixteen granitic rocks and four soils) were collected from different parts of Adham governorate (Adham, Haqal Al-Jaizah), to assess the radiological hazard cancer risk perspectives. is situated in a valley between two mountain chains, where much water supply for drinking, house use irrigation comes wells collecting rains. The activity concen...
