摘要
Recently, due to progressions in radiation detection systems, the capability to monitor radiation on the ground by employing detection systems high above the ground has been developed. Therefore, how to map radiation distributions on the ground based upon measured data in air is an important question. One kind of reconstructing algorithm for solving this problem is introduced in this paper. This algorithm reconstructs the radiological contamination distribution through solving the detection response factors equation set (DRFES). The study shows that the reconstructing algorithm performs well when the detection height is lower than 50 m. Through this algorithm, the ability to reconstruct the scope of contamination magnitude on the ground by using the measurement data obtained in the air has been established. The algorithm discussed in the paper has the potential to be used in emergency monitoring and nuclear decontamination.
