摘要
放射性检测仪表的测量方式、特点和安装位置,以及放射源γ射线的不可约束性等物理性质,造成了仪表之间相互干扰。通过放射源的防护或者探测器的防护,改善安装条件,准确计算放射源防护罐的辐射角度,以及准确确定辐照面的辐射区域等方法消除干扰,提高放射性检测仪表的测量效果。
The measurement mode,characteristics and mounting position as well as the nonbinding properties of radiation source＇s γ-ray of the radioactivity detection instrument can cause inevitable interference to instruments. Through making use of the protection of radioactive sources or detectors,the improvement on installation conditions,accurate calculation of radiation angle of radiation source protective tank and radiation area of accurate irradiation surface,the measurement effect of radioactive instrument can be improved.
