    Notes: Abstract: The prevalence of vertebral fractures in women increases with age but only about one third of these fractures are symptomatic. On the other hand, the presence of vertebral fractures is an independent risk factor for new osteoporotic fractures. In the present study we examined the hypothesis that differences between armspan and height are related to the presence of vertebral deformities in a cohort of 494 women aged between 55 and 84 years (mean age 67.6 years, SD 8.2 years) who were randomly selected from a large general practice in The Netherlands. Height and armspan were measured and vertebral morphometry of lateral radiographs of the spine was performed. Both height and armspan decreased significantly with age. The correlation between armspan and height was 0.83. Vertebral deformities were present in 32.7% of the women (grade I in 22.4% and grade II in 10.3%). Only the prevalence of grade II deformities rose with age. The variation of the difference between armspan and height in the groups with or without grade II vertebral deformities was comparable and relatively large (range 〉15 cm). The difference in mean values was small between those groups (1.6 cm) and could not differentiate between women with and without vertebral deformities. Our data show that the presence of vertebral deformities cannot be detected by the difference between armspan and height.

    Application of a low-level anti-coincidence gamma-spectrometer for environmental radioactivity measurement (1997)
    Springer

    Notes: Abstract Sensitive environmental radioactivity measurement using direct γ-spectroscopy needs to be carried out under particular low-level conditions as the quantity to be determined generally is very close to the natural background. Passive shielding of the detectors in addition to electronic suppression of Compton background resulting from scattering of high energy γ-rays in the gemanium detector seems to be the most promising approach to obtain statistically well defined peaks within reasonable measurement time. Results obtained with a heavily shielded anti-coincidence spectrometer installed at the Research Center Jülich, ideally suited for the measurement of low-level environmental radioactivity in various materials are described.

    Neutron-activation analysis of trace elements in thyroids (1999)

    Notes: Abstract Neutron activation analysis was used for routine measurement of trace elements in thyroids of inhabitants of Belarus as well as in thyroids of people operated for thyroid cancer. The method chosen allowed the analysis of 28 elements, among them essential and toxic ones, with a good accuracy. The results obtained showed significant differences in the elemental composition of thyroid from the different regions. The changes of elemental composition of thyroids of inhabitants of the Gomel region, where goiter is endemic, seem to be identical to those in the tumor tissue.
