Radioecology
oral (invited speaker)
Although traditionally separate disciplines, radiobiology and radioecology are closely interlinked, and a closer collaboration between them would be of great benefit to both fields. This talk will give a personal view on what the two disciplines can learn from each other, giving examples from current research.
The most obvious area of overlap is radiation effects at the cellular and...

Purpose: Radium is a long lived actinide in the uranium decay chain. In living organisms it completes with calcium and thus can accumulate in organisms exposed to radium as a result of uranium mining and milling activities associated with the nuclear industry. Currently actinides are assigned an RBE (relative biological effectiveness) factor of between 20 and 40 but this value is highly...

In recent years many efforts have been undertaken to develop a system of radiation protection for non-human biota. One of the key issues is an assessment of critical doses and doses rates for flora and fauna species at different exposure conditions. This work presents a database on radiation-induced effects in plants and an example of critical exposure values assessment on the base of data...

The microbial reduction of metals has attracted recent interest as these transformations can play crucial roles in the cycling of both inorganic and organic species in a range of environments and, if harnessed, may offer the basis for a wide range of innovative biotechnological processes. Microorganisms can affect the stability and mobility of the actinides U, Pu, Cm, Am, Np, and the fission...

This paper presents the results of additional environmental radioactivity monitoring carried out by the Radiological Protection Institute of Ireland, RPII, in 2011 following the accident at the Fukushima Dai-ichi nuclear power plant in Japan. It will also compare model predictions with measured air concentrations, demonstrating that the model predictions were broadly in agreement with the...

In spite of the 26 years, past after the Chernobyl NPP accident in 1986, self-purification of the main water bodies in the Chernobyl exclusion zone is extremely slow process. Therefore, ecosystems of the majority of lakes, dead channels and crawls possess high level of radionuclide contamination of all the components. The basic problems of radiation safety of the Chernobyl exclusion zone...
