Estimation of ambient gamma radiation dose and drinking water radon concentration in coastal taluks of Uttara Kannada district, Karnataka

Study on Estimation of Inhalation and Ingestion Dose due to ²²²Rn Concentration in Different Types of Ground Water of Some Taluks of Uttara Kannada District, Karnataka, India

“…Higher activity concentration of 222 observed in water taken from bore well and hand pumps at Haliyal, Bhagavati, Kerosalli, Karlakatta, Nujji ,Ganadahalli, and Pala. This is due to the fact that this region is attributed with granitic gneiss at various depths and the presence of thrusts, faults and shears which provides the way for the upward movement of radon gas with higher radioactivity [22,23].…”

Influences of COVID-19 pandemic lockdown on excess lifetime cancer risk value of natural radiation

“…To calculate the outdoor and indoor occupancy factors for the gamma radiation dose, all researchers usually used the formulas to calculate effective doses per annum (AED), and ELCR values reported by UNSCEAR[ 3 , 11 ]. The effective doses per annum (mSv y −1 ) were calculated using the Eq.…”

Radon concentration measurement and effective dose assessment in drinking groundwater for the adult population in the surrounding area of a thermal power plant

“…Various studies have been performed in different parts of India to measure the radon concentration in groundwater used for drinking purposes. In various states of India, the concentration of radon dissolved in groundwater ranged as follows: 0.87-6.73 Bql À1 in Himachal Pradesh (Singh et al 2016), 0.4-74.37 Bql À1 in Jammu and Kashmir (Kumar et al 2017a(Kumar et al , 2017b(Kumar et al , 2018Kaur et al 2019), 0.14-35 Bql À1 in Punjab (Kaur et al 2017;Kumar et al 2017cKumar et al , 2019Sharma et al 2019Sharma et al , 2020Pant et al 2020), 0.60-57.35 Bql À1 in Haryana (Duggal et al 2017(Duggal et al , 2018Panghal et al 2017;Sharma et al 2017aSharma et al , 2017bSingh et al 2019), 0.50-861.5 Bql À1 in Rajasthan (Mittal et al 2016a(Mittal et al , 2016bDuggal et al 2020aDuggal et al , 2020b, 0.19-160.18 Bql À1 in Karnataka (Srinivasa et al 2015(Srinivasa et al , 2018(Srinivasa et al , 2019Rangaswamy et al 2016;Niranjan et al 2017;Reddy et al 2017;Shilpa et al 2017;Kaliprasad & Narayana 2018;Sannappa et al 2020;Yashaswini et al 2020) Coal-fired power plants are the sources of fly ash, which contains naturally occurring radioactive elements such as 238 U, 232 Th, and their decay products and other toxic elements. Fly ash is generally stored at coal power plants or placed in landfills.…”
