Proton and heavy ion accelerators of the medial energy are very important in science and technology. First of all in the medicine, in the field of elimination of nuclear waste, for the creation safe subscritical reactors and so on. Their usage will help to cure cancer, to develop safety nuclear energetic, to protect environment and so on. Unfortunately large size of the accelerators that could ...

The price system is generally thought to be the epitome of efficiency. In some cases, however, lotteries are preferred to the market as a social decision-making system for reasons of fairness. As recent research as shown, neither procedure is always well accepted among the general population. We analyze the social acceptability of both mechanisms and apply our framework to the allocation of soc...

The Norwegian Radiation Protection Authority (NRPA) has been involved in studies related to the Mayak PA and the consequences of activities undertaken at the site for a number of years. This paper strives to present an overview of past and present activities at the Mayak PA and subsequent developments in the quantification of health effects on local populations caused by discharges of radioacti...

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...

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...
