| Abstract:: |
| Objective To investigate the eye lens dose to the operators who tended to test the quality control of positron emission tomography (PET). Methods Before encapsulation and in preparation of point source, line source 1 and line source 2, the two operators were worn with lens thermoluminescence dosimeter each at the left of the left eye, the front of the left eye, between the right eye and the left eye, the left of the right eye, and the front of the right eye. Measurement and analysis were made of the radiation doses to eye lens received by the operators in order to calculate their maximum annual doses. Results The maximum lens dose was 2 439.80 μSv for the test of 5 PETs. There appears to be the same trend in the eye lens doses for the first and second operators. (χ2=15.629-16.155, P<0.05). The first operator have received higher eye lens dose higher than the second(Z=2.611, P<0.05). Conclusions The dose to the eye lens for a single PET test is relatively low. |
