This paper addresses the noticeable increase of 137Cs activity concentrations in soil and fallout in the area surrounding Zagreb (Croatia) that occurred at the time of the 2011 Fukushima accident. This topic is important for public health as 137Cs is highly toxic due to its long half-life of radioactive decay and chemical similarity to potassium. 137Cs concentrations in fallout were much greate...

This paper describes the Syrian experience with respect to Naturally Occurring Radioactive Materials (NORM) waste produced by the Syrian oil industry. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubular that are considered to contain the highest levels of radium isotopes (Ra, Ra, Ra); this type of waste being current...

Predicting the environmental fate of Cs radionuclides in forest ecosystems is important for the effective management and assessment of radioactively contaminated forest areas. A large proportion of the radioactively contaminated areas in Japan consist of forest ecosystems, and most of these areas are artificial forests that are used for timber production [e.g., Japanese cedar (Cryptomeria japon...

Field trials contribute practical information towards the development of phytoremediation strategies that cannot be provided by laboratory tests. We conducted field experiments utilizing the Cd hyperaccumulator plant Solanum nigrum L., on farmland contaminated with 1.91 mg kg(-1) Cd in the soil. Our study showed that S. nigrum has a relatively high biomass. Planting density had a significant ef...

Abstract Radioactive mercury waste constitutes a significant challenge, as no approved disposal concept yet exists for such in Germany. This work describes decontamination and measurement procedure possible clearance of from nuclear facilities release into reuse or conventional hazardous to reduce the amount repository. The setup were developed evaluated including Monte-Carlo N-Particle® Transp...

Some agricultural lands located in the Vromos Bay area, near the Black Sea coast, Southeastern Bulgaria, have been Ž . Ž . contaminated with radioactive elements uranium, radium and thorium and toxic heavy metals copper, cadmium and lead as a result of mining and mineral processing of polymetallic ores. Laboratory experiments carried out with soil samples from these lands revealed that an effic...

Coal, like most materials found in nature, contain trace quantities of the naturally occurring primordial radionuclides. Therefore, the combustion of coals results in the release into the environment of some natural radioactive elements and in a redistribution of these radioactive elements in the surface soil particularly in the vicinity of coal-fired power plants, where it can modify ambient r...
