| 摘 要： | 通过理论分析结合长江武汉航道工程局挖泥船施工现场情况提出以清水计数率作为密度测量精度的评价指标，在此基础上推导出针对不同排泥管径所需放射源活度的计算公式，据此结合现场条件建立放射源核素及活度的选择条件，为提高设备的有效性提供依据。

| Abstract: | Through theoretical analysis combined with the spot situation, the count rate of water was proposed as the evaluation index of density measurement accuracy. Combining field conditions, the formula for calculating the activity in different diameters was derived, and the conditions for selecting kind of isotope and activity was given. The author recommended that when the diameter of discharge tube is not more than 800mm, 137Cs is better, otherwise 60 Co is better. |
