Abstract

Natural background radiation levels are measured in 17 dwellings selected randomly in and around Karimnagar city of Telangana using a portable μR-survey meter for a period of one year on quarterly basis. These levels are found to be minimum at Gangadhara village and maximum at Peddur village. Elevated levels of radiation at Peddur village can be attributed to the uraniferous rocks present in that area. The ratio between the indoor to outdoor radiation levels is varying between 0.68 and 1.22 against the world average of 1.2. Variation of natural background gamma radiation levels with different types of buildings is also discussed.
