Objective: To explore the quality control testing of positron emission tomography (PET) equipment for detecting the exposure dose of the operator's eye lens. Method: During the quality control testing of 5 PET machines in Shandong Province、 before packaging、 during the production of point source、 during the production of line source 1、 and during the production of line source 2、 they were tested on the left side of the left eye、 in front of the left eye、 in the middle of the left eye、 and in front of the right eye、 respectively Wear a personal dosimeter with a thermoluminescent lens on the right side of the right eye. Measure and analyze the radiation dose to the lens of the operator's eye、 and calculate its maximum annual exposure dose. As a result、 5 PET machines were tested、 and the maximum dose to the lens of the operator during the test was 2439.80 μ Sv、 the dose to the left and right lenses of the first and second detection operators showed the same trend (x2=15.629~16.155、 P<0.05). The exposure dose to the lens of the first detection operator was higher than that of the second detection operator (Z=2.611、 P<0.05). Conclusion: Single PET detection results in a lower level of exposure dose to the lens of the detection operator
