Radiation doses received by humans in their dwellings - A baseline report on radionuclides exposure from construction materials used in Chennai, Tamil Nadu, India.

Gamma-ray spectrometry was employed to assess the activity concentrations of primordial radionuclides (U, Th, and K) in various construction materials, including those used for building, roofing, furnishing, flooring, and plastering. The measured activity concentrations of the radionuclides ranged as follows: U (25 to 477 Bq kg), Th (below detection limit to 239 Bq kg), and K (285 to 1915 Bq kg). Based on these values, the materials were categorized in descending order of radioactivity threat as: Furnishing > Roofing > Building > Flooring > Plastering.

Comparative genomics of zoonotic pathogen of animal origin to understand its diversity.

Unlabelled: , a zoonotic pathogen causing enteric diseases in different animals and humans. A comprehensive study on the presence of toxin genes and antimicrobial resistance genes based on genome data of in animals is scanty. In the present study, a total of 15 isolates were recovered from dogs and isolates with toxin genes (D1, CD15 and CD26) along with two other non-toxigenic strains (CD28, CD32) were used for whole genome sequencing and comparative genomics.

Developing and Validating Quantitative Food Frequency Questionnaire to Assess Dietary Vitamin D Intake among Adults in Indian Population.

The objective of this study is to create and validate a quantitative food frequency questionnaire (FFQ) for the assessment of Vitamin D intake among adults in Indian population. A quantitative FFQ was developed consisting of Vitamin D dietary-rich sources selected from IFCT, 2017. Further, the FFQ was validated against 24-h dietary recall from randomly selected 385 adults, both men and women above 25 years of age.

Investigating radiation profiles and conducting risk assessment for ecological and environmental components on Vaan and Koswari islands in the Tuticorin group of islands, India.

Natural radioactive concentration assessment was conducted on sediment, water, and biota obtained on Vaan and Koswari islands in the Tuticorin group of islands, Tamil Nadu, India. For biotic and abiotic components, radiation profiles such as gross alpha, beta, primordial radionuclide, polonium, and lead analyses were performed. The gross α and β range from BDL to 15.

Microbial consortium and impact of industrial mining on the Natural High Background Radiation Area (NHBRA), India - Characteristic role of primordial radionuclides in influencing the community structure and extremophiles pattern.

The present investigation is the first of its kind which aims to study the characteristics of microbial consortium inhabiting one of the natural high background radiation areas of the world, Chavara Coast in Kerala, India. The composition of the microbial community and their structural changes were evaluated under the natural circumstances with exorbitant presence of radionuclides in the sediments and after the radionuclide's recession due to mining effects. For this purpose, the concentration of radionuclides, heavy metals, net radioactivity estimation via gross alpha and beta emitters and other physiochemical characteristics were assessed in the sediments throughout the estuarine stretch.
