Abstract The study aimed to determine the impact of COVID-19 on values of annual effective dose equivalent of the natural gamma dose rate of Balod, Durg and Bemetara districts of Chhattisgarh (India). COVID-19 is a severe problem for many countries and to control and prevent the spread of this problem, the lockdown approach has been implemented in many countries, including India. In this lockdown situation, almost all people stay at home for 24 h. Due to the present status of COVID-19, the Indian government also fixed the 67 days lockdown and one day was already successfully done as Janta Curfew, which worked the same as a lockdown. The value of indoor gamma dose rates was reported to be higher in most places compared to the outdoor gamma dose rate, but in this pandemic situation, occupancy factor values are not applicable as recommended by UNSCEAR for calculation of annual effective dose equivalent (AEDE). Therefore, the present study introduces the new equations, which can measure the extra AEDE value during lockdown for adults, children and infants.

Introduction COVID-19 due to Coronavirus is distressing many countries and their territories around the world [1, 2]. This pandemic emerged during December 2019 from Wuhan city of China to other parts of the world [3]. In this problematic situation, every country is working on applying many strategies to prevent and control the spread of coronavirus among their people. Many countries already applied tremendous strategies, which include one of the dominant strategies is lockdown of state or country. The Indian government has also adopted this strategy and before applying lockdown, the prime minister of India has requested the Indian public to follow selflockdown as called Janta Curfew for one day (22 March 2020), which was efficacious. The Indian government has declared a total of 21 days (from 24 March 2020 to 14 April 2020) as a lockdown, which extended three times from 15 April 2020 to 3 May 2020; 4 May 2020 to 17 May 2020 and 18 May 2020 to 31 May 2020 [4]. The annual effective dose of gamma radiation is the most important value to estimate * Manoj Kumar Jindal [email protected] 1

the effect of gamma radiation on mankind, UNSCEAR was given the formula for calculation of these values and this formula is utilized around the world for estimation of AEDE values [5]. The annual effective dose is calculated by using indoor and outdoor gamma dose and based on many studies, indoor gamma dose rate values are usually higher than the outdoor gamma dose rate, except in a few countries or territories of the world [5, 6].
