The precipitation of strontium in highly concentrated nitric acid is often used standard radiochemical methods for 90Sr separation. In this work, the description Sr behavior such conditions was studied point speciation simulation. Standard method based on Phreeqc software considered but two problems underlined limits approach to study process: inappropriate ionic strength correction model (for ...

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...

abstract background: measures to protect the public following an accidental release of radionuclides to the environment will depend on the circumstances including the extent of the potential hazards. the projected levels of risk are an important precondition in emergency planning. the levels can be expressed in terms of concentration levels in the environment or in foodstuffs. these derived int...
