摘要：
Measurement of environmental gamma dose in air in Ho Chi Minh city, Vietnam has been conducted at 2245 locations using a portable dosimeter installed on a motobike with GPS integrated and positioned 1 m above the ground surface. Cumulative gamma dose rates have also been measured using the TLD dosimeters located at 20 fixed locations around the city to evaluate the total component and the contribution of cosmic rays in the rainy and dry seasons. The gamma dose rates in the city were found in the range of 0.05–0.18 μSv/h with the average value of 0.10 μSv/h. The cumulative gamma dose in the dry season is greater than that in the rainy season by about 15%.
