摘要
环境辐射航空测量中,需要对航空测量结果的准确性进行评价。本文以评价环境辐射剂量率航测结果的准确性为目的,探索了空地比对的方法。从航测与地面测量的关系入手,提出开展面积性比对、单线测量比对和测区单点比对三种空地比对方法,分别在三门核电站和海阳核电站的环境辐射本底航空测量调查项目中开展了空地比对研究。通过在普陀山基线上开展面积性比对和单线测量的空地比对,对引起测量偏差的因素进行了分析,空地测量相对偏差分别为-0.2%和-4.0%;在诸往镇基线上开展单线测量的空地比对,相对偏差为-8.7%;在海阳核电站航测区开展测区单点比对实验,对单点比对中偏差较大的测点开展了地面实地调查工作,查明了引起这些差异的主要原因。通过三种方法间的比较分析得出:①以开展航测评价为目的的空地比对,使用面积性比对效果最佳,但地面实际测量要求较高;②单线测量比对效果次之,但通过挑选有利的测量区域,可以弥补该方法的不足;③测区单点比对受到测区复杂环境的影响往往达不到评价目的,其实用性较差。因此建议可将面积性比对和单线测量比对作为环境辐射航空测量质量评价的标准方法。
Evaluating the preciseness of airborne gamma ray measurement result is necessary in airborne survey of environmental radiation.The comparing method of airborne gamma ray measurement and in situ measurement was studied in the paper.This method is mainly to evaluate the preciseness of environmental radiation dose rate in airborne radioactive survey.Considering the relation of airborne gamma ray measurement and in situ measurement,the method of area comparison,single line measurement comparison and single sample data comparison were discussed.The three methods were tested during the environmental radiation background investigation project of Sanmen NPP and Haiyang NPP respectively.By the method of area comparison and single line measurement comparison in Putuoshan test line,relative errors are -0.2% and -4.0% respectively about airborne gamma ray measurement and in situ measurement.And at the same time,possibility reason of occurred error was discussed in the paper.The method of the single line measurement comparison was tried in Zhuwangzhen test line.Relative error is -8.7% about airborne gamma ray measurement and in situ measurement.Single sample data comparison method was tested during the survey area of Sanmen Nuclear Power Plant.And in situ investigation was done about the suspicious data.The major reason was explained in the paper.Through the last analysis of the three methods,the following result was named out.①The best result can be gained through the method of area comparison about comparison of airborne gamma ray measurement data and in situ data for evaluating quality of airborne gamma ray measurement,but more restricted condition was necessary in situ survey.②The better result can be gained through the single line measurement comparison.But the shortcoming can be remedied through choosing advanced survey area from the whole project.③The method of single sample data comparison was restricted and cannot be got better evaluation result because of complicated environmental.The paper recommends that the method of area comparison and single line measurement comparison can be a standard method during quality evaluation of airborne gamma ray measurement for environmental radiation.
