In routine monitoring of radiation workers to detect internal contamination due to Pu/Am, it is assumed that intake has occurred at the midpoint of the monitoring interval. Radiation worker is normally monitored at the end of the annual monitoring interval, within a span of ±1 month under a routine in vivo monitoring program. An uncertainty is introduced in intake estimation as the time of intake can vary over the entire monitoring interval. In this work, uncertainties introduced in the intake estimation of Type M and S compounds of Pu/Am are evaluated due to unknown time of intake for annual and biennial monitoring frequency.

The distribution of naturally occurring radioactive materials (NORM) generated/discharged in nonnuclear industries such as coal combustion residuals from different coal-based power plants, fertilizer, construction, tobacco, and other industries into the environment, has not been reviewed in the Indian context. In the present review, systematic survey and analysis of the reported occurrence of U238, Th232, and K40 in these nonnuclear industrial sectors is discussed. Most of the data compiled and described in this review are sourced from major popularly referred, peer-reviewed scientific journal publications since the year 2005. Apart from radioactivity levels in products from nonnuclear industrial sectors different radiological indices such as absorbed dose, dose rate, etc., are also compared and discussed. Overall, this review presents a comprehensive analysis of NORMs in nonnuclear industrial sectors of India.

Gamma spectrometry of the KAMINI reactor coolant lines at the selected spots/locations was carried out during 20kWt power and shutdown using portable spectrometers such as RIIDEye-X, RayMon (Cadmium Zinc Telluride), and hyper pure germanium.133Xe (81 keV),85m Kr (150 keV), and 135Xe (250 keV) isotopes could be identified. The spectra results did not indicate the presence of internal contamination due to any corrosion activation products such as 56Mn, 59Fe, 60Co, and fission products. The gamma radiation level observed during reactor power on the selected locations is only due to the fission product noble gases (FPNGs) and their short-lived radionuclides 88Rb and 138Cs generated and not any pipeline internal contamination.137Cs and trace quantities of 60Co were identified in the mixed bed regenerated liquid. The presence of 137Cs could be attributed due to the tramp fuel fissions.
