An experimental system was developed to study the diffusion rate of radon (²²²Rn) gas through porous media as a function of soil porosity/grain size and soil water content. Columns with different grain sizes, soil water content and soil depths wer

The analysis of materials containing several elements used to be a difficult problem for analytical chemists, so a well established sequence of wet chemical qualitative tests were performed to ensure each element was detected. Quantitative tests coul

High pre- and post-irradiation fading prevents the attainment of high accuracy in dosimetry measurements, especially in routine dosimetry when the exact duration and time of exposure are not known. An attempt was made at the Soreq Dosimetry Centre to

Cross sections were measured by the stacked-foil technique over the energy range of 2–36 MeV for 3 He-particle induced nuclear reactions on natural Ni leading to the formation of 62,65 Zn, 60,61 Cu, 56,57 Ni, 55,56,57,58 Co, 52,53 Fe and 52 Mn. The

The triplet-triplet absorption spectra have been determined by laser flash photolysis for ortho, meta and para dichlorobenzene. The wavelength of maximum absorption λmax was 290 nm for both the ortho and meta isomers and was 310 nm for the para isom

Proton and helium ion induced nuclear reactions, with energies lower than the uranium-fission Coulomb barrier, are proposed for the activation analysis of impurities in uranium. The reaction products were identified by gamma spectroscopy using a Ge(L
