依据国家有关标准和参照ISO/DIS 21909标准的规定和要求,对放置近2年的BD-PND(BubbleDetector Personal Neutron Dosimeter)中子气泡探测器的均匀性、线性、中子个人剂量当量的响应、重复性和角响应等主要技术性能进行了检验。结果表明,基本符合标准规定的要求。采用修正的响应值可以用于低水平的个人中子剂量测量。因这些探测器的寿命将近终点,应谨慎使用。
According to the national standards and the requirements of ISO / DIS 21909, the response to the uniformity, linearity and individual dose equivalent of neutron bubble detector of BD-PND (BubbleDetector Personal Neutron Dosimeter) Repeatability and angular response and other major technical performance tests. The results show that the basic requirements of the standard. Using a modified response value can be used for low level personal neutron dose measurement. Due to the near end-of-life of these detectors, they should be used with caution.
