The radioactive material in urine after parenteral radioactive hydroxocobalamin is composed of radioactive cyanocobalamin, radioactive hydroxocobalamin, and a radioactive anionic complex. Studies in vitro suggest that these materials have a similar microbiological activity. Comparison of the amounts of radioactive and microbiologically active material in urine after parenteral radioactive hydro...

The Fukushima Daiichi Nuclear Power Plant accident released large amounts of radioactive substances into the environment and contaminated the soil of Tohoku and Kanto districts in Japan. Removal of radioactive material from the environment is an urgent problem, and soil purification using plants is being considered. In this study, we investigated the ability of 12 seed plant species and a cyano...

The global demand for clean energy is growing, as the World looking ways to compensate Green House Gases (GHG) emissions and fight warming through what being called transition. In this context, present article has its guiding question: can solar panels be used radioactive sources generation? objective of study was explore potential usage with sources, a cogeneration systems. This documental lit...

Dilution is the mixing of radioactive waste with non-radioactive material, whereas downblending is the mixing of high-level radioactive waste with low-level radioactive waste. These processes have been applied predominantly at nuclear sites as part of the decontamination procedures for the disposal of blended wastes in licensed facilities. Proper health and safety assessments should be carried ...

Section 20.1204 of 10 CFR Part 20, "Standards for Protection Against Radiation," requires that each licensee, when required by 10 CFR 20.1502, take suitable and timely measurements of quantities of radionuclides in the body, quantities of radionuclides excreted from the body, concentrations of radioactive materials in the air in the work area, or any combination of such measurements as may be n...
