Abstract Mandatory eye lens monitoring for exposed workers who are liable to receive an equivalent dose to the lens of the eye higher than 15 mSv in one year, required by the new European Basic Safety Standard 2013/59 and the recommendation given by the International Commission on Radiological Protection to lower the annual dose limit for the lens of the eye to 20 mSv, have put dosimetry services using Panasonic dosemeters in a difficult position. There are no commercially available eye lens dosemeter holders to fit Panasonic TLD pellets. Therefore, we designed and 3D printed inexpensive, splash proof, reusable and comfortable holders to fit a Panasonic nLi2nB4O7:Cu pellet. The eye lens dosemeter consists of an acrylonitrile butadiene styrene (ABS) plastic holder with a slot for a TLD pellet. The slot with the TLD pellet is covered by a heat-shrink tube and shortly heated with hot air to shrink wrap. Results of combined energy/angular response measurements, for all photon radiation qualities used, relative to N-100 at 0° as the reference energy, were within IEC 62387:2012 limits. Additionally, electron spin resonance spectroscopy was used to test the effect of irradiation to the degradation properties of the plastic ABS holder. The dosemeter is to be worn fixed to a headband, close to the eye, on the left side of the head or in the middle of the forehead.

用于介入放射学和介入心脏病学的 3D 打印眼晶状体剂量计支架

摘要 根据新的欧洲基本安全标准 2013/59 和国际委员会提出的建议,对可能在一年内接受高于 15 mSv 的眼睛晶状体等效剂量的暴露工人进行强制性眼晶状体监测。放射防护将眼睛晶状体的年剂量限制降低到 20 毫希沃特,使使用松下剂量计的剂量测定服务陷入困境。没有市售的眼晶状体剂量计支架适合松下 TLD 颗粒。因此,我们设计并 3D 打印了廉价、防溅、可重复使用且舒适的支架,以适合松下 nLi2nB4O7:Cu 颗粒。眼晶状体剂量计包含一个丙烯腈丁二烯苯乙烯 (ABS) 塑料支架,带有一个用于 TLD 颗粒的插槽。带有 TLD 颗粒的插槽被热缩管覆盖,并用热空气短暂加热以收缩包装。对于所有使用的光子辐射质量,相对于 0° 的 N-100 作为参考能量,组合能量/角响应测量的结果在 IEC 62387:2012 限制范围内。此外,电子自旋共振光谱用于测试辐照对塑料 ABS 支架降解性能的影响。剂量计应固定在头带上、靠近眼睛、头部左侧或前额中间。电子自旋共振光谱用于测试辐照对塑料 ABS 支架降解性能的影响。剂量计应固定在头带上、靠近眼睛、头部左侧或前额中间。电子自旋共振光谱用于测试辐照对塑料 ABS 支架降解性能的影响。剂量计应固定在头带上,靠近眼睛,在头部左侧或前额中间。
