Calibration of carborne gamma-ray spectrometry systems for (137)Cs is carried out with a source successively placed at 791 positions within an area of 34 m x 62 m. A computer model supplements the measurements. Hereby a sensitivity map for a surface contamination is generated as well as line and area sensitivities. Another model converts surface sensitivity to sensitivity for a deep contamination. Use of the sensitivity map for a non-homogeneous distribution of (137)Cs is demonstrated. Applications of line sensitivities for special tasks are discussed.
用于校准车载伽马射线能谱系统中¹³⁷Cs的源,依次放置在34米×62米区域内的791个位置上。通过计算机模型对测量结果进行补充。由此生成了表面污染的灵敏度图以及线灵敏度和面积灵敏度。另一个模型将表面灵敏度转换为深部污染的灵敏度。展示了¹³⁷Cs非均匀分布的灵敏度图的应用。讨论了线灵敏度在特殊任务中的应用。
