Abstract

The absorbed dose rate in air was measured using the car-borne survey technique on Phu Quoc Island, Vietnam in December 2015. The average absorbed dose rate in air measured on asphalt pavement was 61±15 nGy h^-1 and higher dose rates in air were observed along asphalt roads, whereas the average value measured on unpaved roads was 29±6 nGy h^-1, meaning the former average dose rate was 2.0 times higher. The average dose rate for the entire island was 44±20 nGy h^-1. The estimated annual external effective dose was 0.29 mSv y^-1, which is 60% of the worldwide average.
