The absorbed dose rate in air was measured all over Phu Quoc Island, Vietnam after infrastructure projects were undertaken, and changes on dose rates related with these projects were evaluated. The median (range) absorbed dose rate in air for the whole island was 48 nGy/h (19 – 110 nGy/h); as a consequence, dose rate was increased 1.3 times compared to that before infrastructure projects. In the dose rate distribution map, the impacts on dose rate related with constructions of hotels, resorts and roads were clearly displayed. Phu Quoc Island was a sensitive area to changes of absorbed dose rates in air because the original radiation level was low.
