Abstract Safe storage of radioactive materials is based on three universal radiation protection principles. Justification, optimization and dose limits are applicable to the risk assessment, acknowledging hazards in each procedure delivery, usage, disposal materials. Failure Modes Effects Analysis method (FMEA) developed for evaluation common practices. In this work FMEA exploited radiological ...

The University of Texas Medical Branch (UTMB) at Galveston is a large academic medical center with about 12,700 employees, 350 radioisotope research labs and 200 permitted radioactive materials users. Consequently, UTMB generates a fairly large amount of radioactive waste. The majority of this waste contains short-lived radionuclides, such as 32P, 33P, and 35S, which are held for decay and then...

IAEA BULLETIN, 42/3/2000 Releases of radionuclides to the atmosphere or to surface waters from nuclear and other facilities using radioactive materials are generally strictly controlled to protect the health of people living in the local and regional environments. Since the 1970s, the IAEA has issued guidance on the control of discharges and, in doing so, it has elaborated upon the basic recomm...

Assay of the radioactive content of waste drums is important for inventory and waste disposal purposes. The sampling of the drum content is a difficult, time and labor consuming procedure, involving special radiation protection considerations. On the other hand the characterization of waste drums containing radioactivity by measuring the drum as a whole (without opening) offers overall simplici...

OBJECTIVE The aim of study was to develop a rapid assay, dye labelled monoclonal antibody assay (DLMAA), using non-radioactive organic synthetic dyes for identification of Toxic Shock Syndrome Toxin-1 (TSST-1) producing strains of Staphylococcus aureus. MATERIALS AND METHODS The assay protocol required only two simple steps; addition of TSST-1 antigen to a nitrocellulose membrane and then add...

Cementitious materials are considered to be a waste form for the ultimate disposal of radioactive materials in geological repositories. We investigated by means of atomistic simulations the encapsulation of strontium-90, an important radionuclide, in calcium–silicate–hydrate (C–S–H) and its crystalline analog, the 9 Å-tobermorite. C–S–H is the major binding phase of cement. Strontium was shown ...
