摘要
从航空放射性测量、数据处理、辐射异常识别以及地面查证全过程进行分析,探讨航空放射性测量技术搜寻辐射异常能力,结果表明,1)航空放射性测量技术可快速、大范围且不受地面交通和地形地貌等限制快速搜寻辐射异常;2)航测数据可识别很小范围内的人工、天然辐射异常,初步定位异常区位置,判定引起异常的原因;3)结合地面查证工作,可精准的圈定辐射异常范围、分布特征、影响程度及引起原因;4)地面与航空测量数据异常表现特征一致,验证了航测方法的有效性。充分体现了航空放射性测量在搜寻辐射异常方面的准确性及可行性。
This paper analyzes the whole process of aerial survey,data processing,radiation anomaly identification and ground verification,and studies the ability of airborne radiometric survey technology to search for radiation anomalies.The results show that 1)airborne radiometric survey technology can quickly search for radiation anomalies in a large range and without the restrictions of ground traffic and topography;2)aerial survey data can identify artificial and natural radiation anomalies in a very small range,preliminarily locate the location of the abnormal area,and determine the cause of the anomaly;3)combined with the ground verification work,it can accurately delineate the scope,distribution characteristics,impact degree and causes of radiation anomalies;4)the abnormal characteristics of ground and aerial survey data are consistent,which verifies the effectiveness of aerial survey method.It fully reflects the accuracy and feasibility of airborne radiometric survey in searching for radiation anomalies.
