    Energy levels in46Ti (1968)
    Springer
    The European physical journal 215 (1968), S. 39-55 
    Details
    ISSN: 1434-601X

    Topics: Physics
    Notes: Abstract The gamma-ray spectra of several resonances in the45Sc(p, γ)46Ti reaction were measured using a 5 cm3 Ge(Li) detector. A thick target was bombarded with 1377 and 1660 keV protons, several resonances were therefore excited at each proton bombarding energy. The decay and energy of 30 excited levels were investigated. The intensity of all transitions to the ground state agrees within an error of about 9% with the total intensity of all transitions starting from the proton capture states, which indicates that low energy transitions between high-excited levels are of no importance. We have calculated a theoretical primary gamma-ray spectrum that fits the experimental averaged spectrum rather well.

    Gamma-spectrometric determination of uranium isotopes in biofuel ash (1987)
    Springer
    Journal of radioanalytical and nuclear chemistry 115 (1987), S. 211-216 
    Details
    ISSN: 1588-2780
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Gamma-ray measurements have been performed on biofuel samples using a planar intrinsic Ge detector. The samples were first homogenized and then packed into 90 ml plastic tubs. The radiation from each sample was usually measured for 1 to 2 days. The intensity of the 63.3 keV γ-ray in234Th was used to determine the amount of238U present. The amount of235U can be determined from the intensity of the 143.8 keV γ-ray.

    Detailed early measurements of the fallout in Sweden from the chernobyl accident (1987)
    Springer
    Water, air & soil pollution 35 (1987), S. 335-346 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Low-volume samplers collecting ambient aerosols in two size fractions have been used to collect radioactivity from the Chernobyl accident. The samplers were situated near light-houses on the east coast of Sweden and samples were collected during consecutive 12-hr periods. Activity concentrations of 95Zr, 95Nb, 103, 106Ru, 131I, 134, 136, 137Cs, 140Ba, 140La, 141,144Ce, and 239Np were measured with a Ge(Li) detector. The transportation time between Chernobyl and the two sampling sites is in good agreement with times calculated from air mass trajectories. The main part of the radioactivity was found on particles with an aerodynamic diameter of less than 2 μm.
