| Abstract:: |
| Objective To establish methods of measuring the eye lens dose to interventional staff, to obtain relevant dose data and to provide a scientific basis for reducing eye lens dose. Methods Two kinds of dosimeters, thermoluminescent dosimeter (TLD) and optically stimulated luminescence dosimeter (OSLD), were selected to measure the personal dose equivalent Hp(3) to eye lens of occupational staff in several kinds of interventional procedures, including cardiovascular interventional procedures, cerebrovascular interventional procedures etc. Five types of Digital Subtraction Angiography (DSA) equipment were chosen in the study, including single tube equipment and double tube equipment. Results The eye lens dose Hp(3) to interventional staff varied significantly with different interventional procedures. The lowest dose is shown in the coronary angiography procedure, while the highest dose shown in the cerebral stenting procedure. For the same type of interventional procedure, the eye lens dose to the primary interventionist was the highest. For same interventionist, the dose to the left eye was obviously higher than that to the right eye. In addition, the measured results of OSLD were apparently higher than that of TLD. Conclusions Both TLD and OSLD could be used to measure eye lens dose, and the ways of calibrating TLD to evaluate personal dose equivalent Hp(3) were feasible. The reason of significant difference between the measured results of TLD and OSLD needs further research. |
