Radiation threat due to operation of Uranium mines is negligible as compared to the dose of radiation from natural background, Uranium Corporation of India Limited (UCIL) officials said. Human beings in their day to day life are continuously exposed to natural background radiation, the UCIL officials told an awareness programme attended by over 100 students and teachers. The programme was held at Sidhu Kanhu High School, at Kedo near the Uranium township of Jadugora, about 22 km from here, yesterday. Addressing the gathering, S Tripathy, Assistant Superintendent (Geo) and Deputy Manager (Pers and CC), S Hembrom explained the basics of exploration of uranium, its mining and milling as well as the basics of radiation and the myths about radiation. Doubts raised by the participants were clarified and an interactive session involving a mix of powerpoint presentation, pictorial display and audio visual films were used to convey the message across the students and teachers. It was the second such programme organized by UCIL in schools, Hembrom said adding that one such programme had been organized in Kendriya Vidyalaya, Surda, near Jadugora on September 14 last. Hembrom said the UCIL will continue to conduct the awareness program on regular interval to reach out to school children and community of the surrounding region.
