摘要
用圆筒状石蜡模拟管道油垢,以0.662 MeV的γ射线照射,用散射法模拟测量管道在不含油和充满油的状况下,散射线强度对油垢厚度变化的响应.当筒状石蜡中无油时,射线强度随厚度的增加而增加,有很好的线性关系,响应灵敏,并且理论分析与实验所得数据相符;当筒状石蜡中加入油后,射线强度随石蜡厚度的增大先增加后趋于稳定,在石蜡厚度较小时,响应仍非常灵敏.
Using the cylinder-shaped paraffin to simulate grease stain in petroleum pipelines, the scattering experiments with 0. 662MeV γ-ray are performed to measure the response of grease stain thickness in pipeline full of oil or empty. For the empty cylinder-shaped paraffin, the scattered radiation intensity increases with the increasing thickness and shows a good linear sensitivity response which accords with the theoretical analysis. As the case of oil -containing paraffin cylinder, the scattered radiation intensity increases with the increasing thickness and tends to be stable;and there is good response still in the zone of small paraffin thickness.
