  • Performance of some handheld dosimeters used for gamma–ray ambient dose rate measurements

    A study was carried out on the performance of some handheld dosimeters that are used for measuring ambient gamma dose rates. A CsI scintillation–based and two GM–based dosimeters were used to measure the absorbed dose rates in an indoor environment, inside a lead shield, on different floors of a building, in a desert environment and in a boat on the Arabian Gulf. The study showed that while some ...

  • Evaluation of natural radioactivity in rocks of Nilgiri hills and their radiation hazard to mankind

    Twenty three rock samples were collected from various altitudes of Nilgiri hills, Tamil Nadu, India. A survey was carried out to determine the activity concentration of selected radionuclides (238U, 232Th, 40K) by means of gamma–ray spectroscopy using NaI (Tl) detector. From the measured spectra, ...

  • Reduction of bacteriophage MS2 by filtration and irradiation determined by culture and quantitative real-time RT–PCR

    Molecular methods are increasingly applied for virus detection in environmental samples without rendering data on viral infectivity. Infectivity data are important for assessing public health risks from exposure to human pathogenic viruses in the environment. Here, treatment efficiencies of three (drinking) water treatment processes were estimated by quantification of the indicator virus ...

  • Determination of K shell parameters of silver using high resolution HPGe detector spectrometer

    The K shell parameters such as K shell photoelectric cross–section at K shell binding energy, K shell jump ratio, K shell jump factor, the Davisson–Kirchner ratio and K shell oscillator strength of silver have been determined using high resolution HPGe detector coupled to 16K multichannel analyser. In this method the K X–ray photons in the energy region from 8 to 52 keV are ...
