Rock salt is one of the considered storage mediums for radioactive waste, and so the behavior of rock salt in the vicinity of the waste canisters is of great practical interest. The main contribution to the irradiation from a radioactive waste comes

A study is made of the physical characteristics of linear and cyclic polysiloxanes. It is shown that by plotting v20/v70versus v20 (v = kinematic viscosity) it is possible to determine the average number of silicon atoms per molecule in a mixture of

New experimental results are presented on low temperature irradiation ( 18 degrees C) of rock-salt samples which had been exposed to initial doses up to 320 GRad at 100 degrees C. Differential scanning calorimetry ( DSC) shows that the latent heat of

After exposure to ionizing irradiation, mineral zircon exhibits thermoluminescence (TL), which can be used to calculate the irradiation dose and the age of natural samples. Different aspects of the dating procedure based on zircon TL, including labor

We propose a mechanism of void growth in di-atomic ionic crystals due to agglomeration of divacancies produced by interactions between dislocations and excitons. An exciton can cause movement of nearby dislocation jogs, resulting in the creation of e

In this paper we present the results of the first systematic investigation of the geometrical properties of sodium nanoclusters in NaCl using the combined results of differential scanning calorimetry (DSC) and atomic force microscopy (AFM). The melti

Samples of synthetic NaCl crystals have been exposed to different doses of electron irradiation up to 1500 MGy (150 Grad) at elevated temperatures, and studied subsequently by X-ray diffraction. Our experimental results clearly show that there is a c

The mineral zircon, ZrSiO4, belongs to a class of promising materials for geochronometry by means of thermoluminescence (TL) dating. The development of a reliable and reproducible method for TL dating with zircon requires detailed knowledge of the pr

The properties of several unusual Raman scattering peaks observed in heavily irradiated NaCl with vast amounts of colloidal sodium are investigated. A new peak (at 3580 cm(-1)) has been observed far beyond the cut-off limit of the one-phonon spectrum

A kinetic model is formulated for the chemical reaction between radiolytic sodium colloids and gas bubbles, which are brought into contact with each other during the exposure to ionising radiation by the growing voids. The reaction starts with the ev
