Abstract
Radon, a noble radioactive gas, can reach levels that pose a risk to public health in poorly ventilated environments such as residences and buildings. It is a known carcinogenic agent, responsible for the incidence of about 14% of lung cancer in the world. In this work an evaluation of indoor radon, that downtown Rio de Janeiro workers are exposed in working daily life was carried out using an alpha detector (RAD7). The indoor radon concentration and effective dose are below the limits recommended by international standards.
