The Behaviour of134Cs,60Co, and85Sr Radionuclides in Marine Environmental Sediment

Long-term Environmental Behaviour of Radionuclides

T his document provides an overview on the recent advances in Europe concerning the long-term environmental behaviour of radionuclides. It describes and illustrates the most significant scientific achievements gathered through three European projects, PEACE, LANDSCAPE and EPORA, which have been co-funded by the European Commission (DGXII) under the Nuclear Fission Safety Programme. The improvem...

Tracing Fine-Sediment Using Artificial Radionuclides

The environmental characteristics of many artificial gamma-emitting radionuclides provide a number of distinct advantages over other forms of fine-sediment tracer that are readily exploitable when undertaking erosion investigations. This makes them particularly effective for accurately measuring the movement of small quantities of fine-sediment, especially in low-energy environments where soil ...

Biological transfer of radionuclides in marine environments - identifying and filling knowledge gaps for environmental impact assessments

Methodologies have been developed to allow impacts of ionising radiation on marine ecosystems to be evaluated within selected geographical settings. The stages in the assessment require initial information about unit concentrations of radionuclides in reference media to be collated. Activity concentrations for reference groups of flora and fauna and for representatives of these groups are then ...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
