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, the mean activity of 238U, 232Th, 40K are 7.13 Bq kg−1, 30.47 Bq kg−1 and 346.06 Bq kg−1, ...

Spectrometric Probe

SpectroTRACER is a continuous operating measurement system for nuclide specific detection of even lowest level gamma contamination in air (SpectroTRACER-Air/Soil) and in liquids (SpectroTRACER-Aqua). The probe performs spectroscopic analysis of the measurement in order to identify the detected radionuclides. SpectroTRACER is used for radiation monitoring when a standard gamma dose rate monitor is ...
