A set of countermeasures aimed at reducing Cs uptake by plant products includes agrochemical measures based on changes in the soil properties after the application of ameliorants. The dynamic models for studying the effect of the application of potassium fertilizers and dolomite powder on Cs accumulation in plants are presented. Conceptual approaches to the development of models are based on th...

Artificial 90Sr is one of the most important long-lived radionuclides global radioactive fallout from atmosphere after testing nuclear weapons and accident at Chernobyl Nuclear Power Plant in 1986. In addition to atmosphere, secondary contamination Crimea was mainly Dnieper River North Crimean Canal, which occurred until 2014. used as optimal radiotracer for estimating rate sedimentation hypers...

The paper presents the results of radiation risk assessment for staff a nuclear power plant design during basis accident (spent fuel assembly falling on in reactor core or storage pool refueling operations) and beyond (large leakage primary coolant with failure active part emergency cooling system complete blackout 24 h). is based state-of-the-art models from United Nations Scientific Committee...

In the event of a dirty bomb scenario or an industrial nuclear accident, a significant dose of volatile radionuclides such as 137Cs and 90Sr may be dispersed into the atmosphere as a component of fallout and inhaled or ingested by hundreds and thousands of people. To study the effects of prolonged exposure to ingested radionuclides, we have performed long-term (30 day) internal-emitter mouse ir...

Vertical distributions of 239,240 Pu and 137 Cs activity concentrations in the waterlogged non-boggy soil cores sampled vicinity Vilnius City Varėna District were analyzed. The radionuclides appeared soils mainly as a result fallout after nuclear weapon testing atmosphere 1960s due to Chernobyl NPP accident 1986. deposited on surface shores lakes experienced processes translocation accumulation...

Abstract. Artificial radionuclides including radiocesium (134Cs and 137Cs) radiosilver (110mAg) were released into the environment following Fukushima Dai-ichi nuclear power plant accident in March 2011. These particle-bound substances deposited on soils of north-eastern Japan, located predominantly within a ?3000 km2 radioactive fallout plume drained by several coastal rivers to Pacific Ocean....

INTRODUCTION Data derived from sampling at areas contaminated by the Chernobyl fallout have demonstrated the organic layer of soil to be a major pool of radiocesium in forest ecosystems (Linkov and Schell, 1999, Ruhm et al., 1996). Fungi can directly bind or precipitate radionuclides; they also can indirectly affect radionuclide speciation and mobility in forest soils (Gadd, 1996). Fungi are th...

The use of ultraclean air (UCA) in operating theatres reduces the infection rate after joint replacement but some cases of infection still occur. We investigated one possible source of contamination, namely the setting up of instruments in a conventional plenum-ventilated preparation room. We measured bacterial fallout using agar settle plates and compared instruments set up in the preparation ...
