This paper aims to estimate a potential radiological risk from different kinds of coals used for domestic heating in Serbia, by measuring the activity concentration radionuclides and radon exhalation rate. The obtained mass rate ranges (5.3 ? 3.1) mBqkg?1s?1 (70.3 9.4) mBqkg ?1s?1 was highest lignite type coal. It is estimated that coal stored basement could contribute up 50 Bqm?3 indoor at gro...

This latest article in the Federal Funding for Health Security series assesses FY2017 US government funding in 5 domains critical to strengthening health security: biosecurity, radiological and nuclear security, chemical security, pandemic influenza and emerging infectious disease, and multiple-hazard and general preparedness.

The major issue in selecting patients for transarterial chemoembolization (TACE) lies in determining the optimal number of TACE sessions that may benefit patients before switching to other therapies. This is often a subjective decision not based on any standardized protocol. The ART (Assessment for Retreatment with Transarterial chemoembolization) score was recently developed to determine patie...

Background: One of the main sources of exposure to radiation is terrestrial radionuclides in the environment. These radioisotopes are present in the Earthchr('39')s crust and can be increased by human activity such as mining of coal, oil, and minerals. Materials and Methods: In this study, 39 soil samples including virgin and cultivated were collected from around of the Shazand Refinery Complex...

Radiological hazards associated with exposure to Naturally Occurring Radionuclides Materials from gold mine tailings in the province of Gauteng in South Africa were evaluated. A comparison was made with soil samples from a control area. In this study, gamma spectroscopy was used to measure the activity concentrations of these radionuclides in 56 soil samples from the mine tailings and 10 soil s...

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...

Soil samples from the three residential hubs of Chittagong city, Bangladesh were analyzed using gamma spectrometry to estimate radiation hazard due to natural radioactive sources and anthropogenic nuclide (137)Cs. The activity concentration of (226)Ra was found to be in the range 11-25 Bq.kg(-1), (232)Th in the range 38-59 Bq.kg(-1) and (40)K in the range 246-414 Bq.kg(-1). These results were u...
