| Abstract:: |
| Objective To establish the methods for measuring the dose to occupational staff's eye lens in interventional procedures with direct-reading dosimeters, and to realize the real-time monitoring of eye lens dose and warning for high dose rate, thus providing the scientific basis of the staff radiological protection in interventional procedures. Methods Direct-reading dosimeters were calibrated with personal dose equivalent Hp(3). The eye lens doses for occupational staff in different kinds of interventional procedures were measured by the devices with both single- and double X-ray tubes. The data obtained from the direct-reading dosimeters was compared to those obtained from TLDs. Results Direct-reading dosimeters showed good linear fitting with the calibration of Hp(3), and the coefficients of variation were lower than 5%. The average eye lens Hp(3) for the main operator in coronary arteriography and stent implantation in brain obtained by direct-reading dosimeters were 12.0 and 24.5 μSv, respectively, whereas those obtained by TLDs were 11.9 and 22.7 μSv, respectively. The direct-reading dosimeters gave similar trends as TLDs do so. The direct-reading dosimeters were able to provide eye lens Hp(3) in each individual interventional procedure, and to monitor the real-time dose rate as well. Conclusions The calibration of Hp(3) and the data gained by direct-reading dosimeters are reliable. Therefore, the methods for real-time measurement of eye lens dose for occupational staff in interventional procedures are successfully established. |
