Radiation Induced

Electrical conductivity measurements were made for the determination of G (free ions) in some hydrocarbons. The radiation source was a x-ray tube operated at 55 kV. Four quantities were measured for each liquid: 1. the stationary electrical conductivity at low electric field strength during irradiation, 2. the mobilities of the radiation-induced ions, 3. the volume recombination coefficient, and 4. the absorbed dose rate.All measurements were performed with aerated liquids at room temperature. The following G-values were obtained: n-pentane 0,1; n-hexane and n-heptane 0,09; iso-octane 0,11; cyclohexane 0,06; benzene 0,07; decalin 0,04. The standard deviation was estimated to ± 25 per cent.

Glacial Tills

Anisotropy of glacial tills in Lapland revealed with azimuthal galvanic (Terrameter 300 C) resistivity and inductive (Geonics EM-31) electrical conductivity measurements, which were carried out at four test sites. It was found that the azimuthal electrical conductivity parallelled with the preferred orientation of the till fabric at the top of the soil sequences. The present results indicate that azimuthal resistivity and conductivity are depositional in origon and are attributed to the former ice flow directions. Different coil orientations gave information from different depths and resistivity and conductivity anisotropy varied along with depth.
