This study aims at estimating the lifetime cancer risk from the determination of 222Rn concentration
level in some offices in Ogbomoso, Southwestern Nigeria. The measurement of the indoor 222Rn concentration
levels at some offices in Ladoke Akintola University of Technology (LAUTECH) Ogbomoso, Nigeria was
carried out using an active electronic radon gas detector, safety Pro3 (model HS71512) between February and
July 2011. The result of the measurement showed that the average radon concentration is 26.3±4.17 Bq/m3. This
value translated to an annual effective dose of 0.13 mSv/y and lifetime fatality risk of 9.94×10-6. These values
which were found to be higher than values reported for some countries were however lower than the world
average value and below the recommended action level. Thus, the results of this work have shown that the
exposure to indoor radon at the offices considered is of low risk of fatal cancer occurrence due to radon
inhalation.
Key words: Active radon gas detector, cancer risk, LAUTECH, radon inhalation, , ,
