In this study, gross alpha and beta radioactivity in food crops and surface soil collected from Ho Chi Minh City, Vietnam were measured. Based on the annual effective dose from ingestion of food crops, the degree of risk to human health was estimated. We found out that the obtained values of the dose do not exceed the WHO recommended level (290 µSv year−1). The estimated soil-to-plant transfer factors for gross alpha (TFα) and beta (TFβ) for food crops were also presented. It was found that TFα varied in the range from 0.009 ± 0.005 to 0.99 ± 0.06, TFβ varied in the range from 2.26 ± 0.10 to 10.87 ± 0.53 and the maximum values of transfer factors were found in the root of ipomoea batatas.
