Mineral zircon, ZrSiO(4), belongs to a class of materials that can be used as a chronological tool in geology and archaeology for measurements of the natural radiation dose and the sample age by optical methods. The model of optically stimulated lumi

Results of systematic AFM (atomic force microscopy) experiments on heavily and moderatly irradiated NaCl samples are presented. The sodium nanoparticles and structures of nanoparticles are poduced in sodium chloride during irradiation. The AFM images

Exposure of NaCl to high doses of ionizing radiation leads to the formation of nano-particles of metallic Na, very small chlorine precipitates, vacancy voids, and dislocations. A useful way to monitor the stage of the damage formation process is meas

The scintillation properties of BaF2 doped with 0.002 to 10 mol% Ce3+ have been studied by means of X-ray and gamma ray excitation. The luminescence intensity increases with the Ce concentration until a maximum is reached for 0.2 mol% doped crystals.

In this paper we present the progress made to (i) characterize the defect state of ultra-heavily damaged rock salt samples with up to more than 20 at% Na colloids, which had been irradiated with 0.5 MeV electrons at 100 degrees C up to 10(4) MGy (100

Thermoluminescence (TL) manifested by gamma-irradiated mineral zircon has shown a strong TL peak at about 165 °C which is due to recombination of electrons and Dy3+ related shallow hole traps. After they have been removed by a short preheat we have

A mechanism of radiation-induced emission of Schottky defects from extended defects proposed originally for metals has recently been applied to ionic crystals, where it is based on interactions of excitons with extended defects such as dislocations a

In engineering practice, the heat transfer rate by radiation from hot objects to their surroundings is usually calculated with the equation: φ s = A 1 σ(T 1 4 − T 2 4 )[ 1 a 1 + A 1 A 2 ( case1 a 2 −1) ]−1 However, this equation is exactly va

Being the second part of an investigation into the nature of imperfect mixing, this paper discusses the dispersion during the circulation of a tracer pulse, injected into the impeller zone of a turbine-stirred vessel. A model of the imperfect mixer i
