    A Cylindrical Waveguide Structure with Helical Grooves for High Power TWTs (2000)
    Springer
    International journal of infrared and millimeter waves 21 (2000), S. 553-561 
    Details
    ISSN: 1572-9559
    Keywords: TWTs ; slow-wave structures
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract In this work, the field analysis of a cylindrical interaction structure, with helical grooves, and an inner dielectric lining for possible employment in high power TWT amplifiers in the conventional slow-wave regime, is presented. The Ohmic dominance of the microwave power on the walls of this propagating circuit is deduced.

    129I in soil and grass samples around a nuclear reprocessing plant (1991)

    Notes: Abstract Neutron activation analysis was used to determine129I in soil and grass samples around a reprocessing plant. The method involved wet oxidation of samples, using chromic acid, followed by distillation, collection of iodine in alkaline solution, loading on Dowex-1, irradiation and post-irradiation purification steps. The γ-activity of130I isotope of the purified samples was measured for quantitative determination of129I. The experimental results showed that129I and the129I/127I atomic ratio in soil samples varied from 1.09×10−4 to 5.33×10−3 pCi g−1 and 0.10×10−6 to 6.12×10−6, respectively. Further, the geometric mean of soil-to-plant transfer factor (Bv) for129I was found to be 0.16 which was comparable with other published values.

    Determination of 129i in water and air samples near a reprocessing plant by neutron activation analysis (1994)
    Springer
    Water, air & soil pollution 73 (1994), S. 121-129

    Notes: Abstract The neutron activation analysis was used to determine 129I in water and air samples collected in the neighbourhood of a reprocessing plant. The method involved preconcentration of 129I on AgI from water samples, separation of Ag+, followed by distillation, loading on Dowex-1, irradiation and post irradiation purification steps. Filter air samples were wet oxidised follwed by distillation and other chemical procedure steps as described for water samples. The concentration of 129I in rain water and air samples ranged from 0.155×10−3 to 0.327×10−3 Bq L−1 and 0.054×10−6 to 0.295×10−6 Bq m−3 respectively. The average concentration of 129I in seawater samples was 0.157×10−3 Bq L−1. The concentration of 129I obtained in these samples have been translated to dose rates to an individual and have been found to be insignificant.
