The reference values of the massic activities of each nuclide and their associated standard uncertainties were established based on the certified activity value of the standard solutions used for spiking the soil, taking into account the successive dilution steps, the mass of spiking solutions and the dry mass of the soil being spiked. Radionuclide Certified Value Bq kg Standard combined uncert...

Iodine radionuclides in accident releases under severe accident conditions at NPP with VVER are the most radiationimportant with a view to population dose generation at the beginning of the accident. To decrease radiation consequences of severe accidents the technical solutions for severe accidents management have been proposed in MIR.1200 project, with consideration of the measures for suppres...

Marine luminous bacteria were used to monitor toxicity of alpha(Am-241, U-235+238) and beta(tritium) radionuclide solutions. Increase or inhibition of bacterial luminescence was observed under exposure to radionuclides. Radiation toxicity of Am and chemical toxicity of U were demonstrated. Effects of U were similar to those of stable heavy metals: sensitivy was about 10M. Sensitivity of the bac...

Two novel maltol-based ionic liquids, namely [A336][Mal] and [C101][Mal], were synthesized as potential extracting agents for radionuclides from water. These two room temperature task-specific ionic liquids could be easily prepared by anion metathesis starting from commercially available materials. The isolated compounds were characterized by standard analytical methods. Their application as ex...

Targeted radiotherapy has the potential to provide radiation doses from a wide range of radionuclides, some of them suitable for killing single cells while others are more suitable for killing tumor cell clusters of various sizes. A list of 64 radionuclides, including 20 new potential candidates for therapy (73Ga, 75Se, 87mSr, 97Ru, 103Ru, 113Sn, 113mIn, 117Sb, 123Sn, 131Cs, 139Ce, 141Ce, 149Eu...

Nano SiO2 compound with 160 m2/g specific surface area and 20 nm sizes has been irradiated continuously with neutron flux up to 20 hours in various periods in TRIGA Mark II type research reactor. The initial activities of different type radionuclides defined in the result of eight day activity analysis changes between wide range of 1,5 kBq- 1,5GBq. In the result of activity analysis carried out...

The recent events at the Fukushima Daiichi nuclear power plant, in Japan, have raised questions about the accumulation of radionuclides in soils, the transfer in the food chain, and the possibility for restricted land use in the foreseeable future. This article summarizes what is generally understood about the application of agricultural countermeasures as a land management option to reduce the...
