Environmental gamma radiation indoors at Akure, Southwestern Nigeria

Exposures to environmental gamma radiation were assessed by using LiF thermoluminescent dosimeters (TLDs) placed inside family dwellings made out of stone, gravel concrete, brick etc., at Akure, the capital of Ondo State. Southwestern Nigeria for about two and a half months. The results show that houses made out of soil bricks give the least exposures to dwellers. The dosimetric implications are discussed in the text.
