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...

Background: The natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: The natural radioactivity levels (226Ra, 232Th and 40K) in the ceramic tiles were measured using high-purity germanium detector system (HPGe) and the related radiological hazards were assessed by radium equivalent activity (R...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can be dissolved into water. Evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. Materials and Methods In this study,10 samples were collected from ground...

Introduction: Human has always been exposed to background ionizing radiation. Interaction between ionizing radiation and the biological system can lead to changes in cells or tissues inducing diseases, such as cancer. With this background in mind, this experimental study aimed to evaluate the specific activity of water radionuclides in Kermanshah province, western region of Iran. Material and M...

Consumption of fish containing elevated levels radionuclides can lead to undesirable health effects for consumers. People in the Singida Municipality harvest from lakes and ponds granite rocks which are linked with hazardous radioisotopes that may be bio-concentrated by fishes they consume. Currently, no study has ascertained these environments. This was carried out analyse radioactivity 226Ra,...

New Authority Over Radioisotopes One set of regulations delegates new authority over radioisotopes to the Nuclear Regulatory Commission (NRC) and is a direct result of testimony submitted by NRC officials to the U.S. House of Representatives Subcommittee on National Security, Emerging Threats, and International Relations and to the U.S. Senate in 2004. In addition to enhanced security measures ...

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 ...

Background: Phosphogypsum is material produced as a byproduct in fertilizer industry and generally used for building materials. This may contain enhanced radium-226 (226Ra) activity concentration compared to its natural that lead indoor radon accumulation. Therefore, an accurate measurement method proposed this study determine 226Ra phosphogypsum sample, considering the potential leakage from s...

The naturally occurring primordial radionuclides in coals might exhibit high radioactivity, and can be exported to the surrounding environment during coal combustion. In this study, nine coal samples were collected from eastern Yunnan coal deposits, China, aiming at characterizing the overall radioactivity of some typical nuclides (i.e., 40K, 238U, 232Th, 226Ra) and assessing their ecological i...

The activity concentrations of naturally occurring radionuclides 226Ra, 232Th, and 40K were determined in 30 agricultural and virgin soil samples randomly collected from Kedah, north of Malaysia, at a fertile soil depth of 0-30 cm. Gamma-ray spectrometry was applied using high-purity germanium (HPGe) gamma-ray detector and a PC-based MCA. The mean radioactivity concentrations of 226Ra, 232Th, a...
