| Abstract:: |
| Objective To investigate radioactivity levels in the main agriculture products around a uranium mine in Northern Guangxi. Methods The agriculture products and soil samples were collected and analyzed by using HPGe gamma ray spectrometer.Results The specific activity of 226Ra in radish (including leaf), radish leaves and radish, collected in one place, were 45.0, 66.7 and 32.3 Bq/kg, respectively. Those of 226Ra and 238U in the radish soil collected in the same place were 19 672 and 85 917 Bq/kg, respectively. The transfer coefficients of soil-to-radish and soil-to-leaves were 1.61×10-3 and 3.40×10-3, consistent with those reported in relevant literature. Radioactivity levels in agricultural products in another survey was in consistence with those in the national survey for food products. Radioactivity levels in soil elsewhere near the radish site was consistent with the results of the national soil radioactivive background survey. Conclusions The soil in this place has been contaminated by the nearby uranium mine. It is important to investigate this place further and take the necessary measures. |
