| 中文摘要: |
| 调查广东省不同地区饮用水源地水中总α、总β放射性水平，分丰水期和枯水期2次各采集20个不同水样，按照《生活饮用水标准检验方法〓放射性指标》(GB/T 5750.13—2006)，利用BH1227型低本底α、β测量仪测定样品。结果表明，40个水样中总α、总β放射性水平分别为0.017 Bq/L ~0.286 Bq/L 和0.027 Bq/L ~0.397 Bq/L，测量值均在正常本底波动范围之内，放射性指标符合国家《生活饮用水卫生标准》（GB 5749—2006）。 |
| 英文摘要: |
| This paper investigated the total alpha and total beta radiation levels in drinking water sources from different regions of Guangdong province. 40 samples were collected in wet season and dry season, and determined by BH1227 low background alpha beta admeasuring apparatus referring to the Standard Examination Methods for Drinking Water Radiological Parameters (GB/T 5750.13—2006). The results showed that the concentration of total alpha and total beta ranged from 0.017 Bq/L to 0.286 Bq/L and 0.027 Bq/L to 0.397 Bq/L，respectively. All of the measurements were below the limits of Standards for Drinking Water Quality(GB 5749—2006) and within the fluctuation range of the normal background. |
