The Act encouraged states to form regional compacts for the disposal of low-level radioactive waste (LLRW). The Act contained both positive and negative incentives. The positive incentive was a provision that allowed compacts to restrict access to their regional LLRW disposal facility to member states beginning in 1993, thus limiting the amount of waste disposed of in any state hosting a region...

Studies on naturally occurring radioactive material (NORM) in the limestone from the Margalla Hills have been carried out by measuring gamma activity and to access its radiological implications if any. For data acquisition, a High-Purity Germanium detector was employed. The activity concentrations of (226)Ra, (232)Th, and (40)K were found to be 14.32 ± 0.24, 2.05 ± 0.04, and 13.80 ± 0.20 Bq kg(...

This paper presents a triple-continuum conceptual model for simulating flow and transport processes in fractured rock. Field data collected from the unsaturated zone of Yucca Mountain, a repository site of high-level nuclear waste, show a large number of small-scale fractures. The effect of these small fractures has not been considered in previous modeling investigations within the context of a...

The treatment of thyroid cancer using an unsealed source of radioactive materials is usually associated with a large amount of 131I. A major problem for hospital admission of these patients is the waste disposal which requires protection of the public. 152 patients with thyroid cancer admitted to the nuclear medicine department of Said AI- Shohada Hospital for UI I treatment were studied. 1...

Regulations and guidelines for radionuclide waste disposal require detailed information about the characteristics of radioactive waste drums prior to transport to the disposal sites. So it is important to know the accurate radionuclide inventory of radioactive waste. However, estimation of radionuclide concentrations in the drummed radioactive waste is difficult and unreliable. In order to over...

Treatment and disposal of waste radioactive ion exchange resins is one of the most urgent problems for nuclear industries in China. Cement solidification technology has many advantages, such as requiring simple equipment, easy scaling-up, low working temperature, no trouble of gas cleaning and low cost. It is a suitable technology for treatment of waste radioactive resins, and has been widely u...

The nuclear energy industry produces radioactive waste at various stages of the fuel cycle. In the United Kingdom, spent fuel is reprocessed at the Sellafield facility in Cumbria on the North West coast of England. Waste generated at the site comprises a wide range of radionuclides including radiocarbon ((14)C) which is disposed of in various forms including highly soluble inorganic carbon with...
