摘要

医护人员操作未密封的放射性药物可能会造成意外的个人污染,从而导致职业性皮肤辐射剂量。英国《2017 年电离辐射法规》(IRR17)要求在风险评估中纳入可合理预见的事故情景所产生的潜在皮肤剂量。如果这些剂量估计值超过 150 mSv 等效剂量(1 cm2 平均值),则必须将工人指定为分类人员。英国健康与安全管理局(HSE)最近的更新促使英国许多人重新审视核医学工作人员的分类。污染造成的皮肤剂量无法测量,必须进行估算。Varskin+ 是一种被广泛推荐用于估算皮肤剂量的代码。用户在 Varskin+ 中定义模拟情景时的主观选择导致计算出的皮肤剂量差异很大。在撰写本文时,还没有确定的计算方法,所有计算都依赖于理论模型。苏格兰 NHS 卫生委员会已采用标准化框架,为风险评估进行皮肤剂量估算。对 Varskin+ 输入的参数敏感性进行了研究,并对现有证据进行了审查。针对直接皮肤污染、手套污染和针刺伤害,确定了通用的、可合理预见的、最糟糕的事故情景。每种情景的标准化输入和假设都编入苏格兰卫生局采用的协议中。该规程允许各部门在实践中存在差异,但对大部分输入进行了标准化。虽然估计的皮肤剂量仍有很大的不确定性,但这种方法减少了差异,并能对各部门估计的皮肤剂量进行比较。随着收集到更多的证据来完善标准化假设,该框架有利于不断改进。对苏格兰核医学工作人员的皮肤剂量进行了逐项任务估算,许多工作人员因此被指定为分类人员。

Occupational skin dose from radionuclide contamination: one country's approach at standardising skin dose estimates using Varskin.

The manipulation of unsealed radiopharmaceuticals by healthcare workers can cause accidental personal contamination leading to occupational radiation skin dose. The UK Ionising Radiations Regulations 2017 require that potential skin doses arising from reasonably foreseeable accident scenarios are included in risk assessments. Workers must be designated as classified if these dose estimates exceed 150 mSv equivalent dose averaged over 1 cm2. Updates from the UK Health and Safety Executive recently prompted many in the UK to review the classification of workers in Nuclear Medicine. Skin dose from contamination cannot be measured, it must be estimated. Varskin+ is a code that is widely recommended for estimating skin dose. The subjective choices made by users when defining modelled scenarios in Varskin+ lead to significant variation in the calculated skin doses. At the time of writing there is no definitive calculation method and all calculations rely on theoretical models. NHS Health Boards in Scotland have adopted a standardised framework for performing skin dose estimates for risk assessments. The parametric sensitivity of Varskin+ inputs were examined and the available evidence was reviewed. Generic, reasonably forseeable, worst-case accident scenarios were decided upon for: direct skin contamination, glove contamination and needlestick injury. Standardised inputs and assumptions for each scenario were compiled in a protocol that has been adopted by the Scottish Health Boards. The protocol allows for differences in practice between departments, but standardises most inputs. While significant uncertainty remains in the estimated skin doses, this approach reduces variation and enables the comparison of estimated skin doses between departments. The framework facilitates continuous improvement as more evidence is gathered to refine the standardised assumptions. Task by task skin dose estimates were made for workers in Nuclear Medicine in Scotland and many workers were designated classified as a result.

期刊介绍: Journal of Radiological Protection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes: dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments. The journal encourages publication of data and code as well as results.
