This paper describes the importance of watermarks reproduction, in particular the advantages and potentiality of beta-ray technique’s application to this aim is emphasized. The method involved a radioactive carbon sheet which emits radiation that images a photographic film. After a conventional processing the film produces an exact copy of the watermark. Techniques which give similar results are also considered. © 2000 American Institute of Physics.

    The activity concentration of natural radionuclides and 137Cs in the bottom sediments cores from Kuwait Bay have been determined by γ-ray spectrometry. Particular attention was devoted to the exact determination of two uranium isotopes: 235U and 238U in order to find any presence of depleted...

    Almost sixty years effort to determine the neutrino mass from experimental β-ray spectra resulted recently in the model independent limit of mv<2.3 eV/c2. The Karlsruhe Tritium Neutrino Experiment (KATRTN) should improve this limit to mv<0.2 eV/c2, while the neutrino mass of 0.3 and 0.4 eV/c2...
