摘要：
To verify quality of irradiated products by a 3.9PBq single plate (1m×1m) source, Ag2Cr2O7 dosimeters were used for measuring extreme doses in three kinds of Chinese medicine in a actual irradiation area of 1.4m×1.4m facing the source. The product cartons were piled on the irradiation area, and their positions were exchanged to improve dosimetry uniformity of the products. The dosimeters for monitoring the minimum dose were placed in center of the cartons. The minimum doses of the three kinds of Chinese medicine products were 2.98, 1.03 and 1.37kGy respectively, and the maximum doses were 4.61, 2.00 and 2.24kGy, respectively. The dosimetry uni- formities were 1.55, 1.94 and 1.64, respectively, which are within the quality control requirement of U≤2.
