Radiation dose monitoring using thermoluminescent detectors is currently one of the main methods of personal or environmental dose monitoring in China. In order to solve the problem of uniformity screening before the use of thermoluminescent detector, and the complexity of the measurement process. Test dose and thermoluminescent peak counts normalization were used to optimize the measurement process of thermoluminescent detectors. With the simple irradiation device, the same batch of thermoluminescent dosemeters for radiation environment monitoring were measured using the optimized and general measurement processes. The relative error of the dose values of the two was within ±5%, which satisfied the accuracy requirements of thermoluminescent dosemeters in the process of monitoring the dose of ionizing radiation to the individual or the environment. The results show that the optimized thermoluminescent dosimetry process reduces detector uniformity performance requirements and improves the applicability of the process. It provides a high-precision, high-efficiency and low-cost measurement method for personal or environmental dose monitoring in China.

使用热释光探测器进行辐射剂量监测是目前中国个人或环境剂量监测的主要方法之一。为解决热释光探测器在使用前需进行均匀性筛选以及测量过程复杂的问题,通过引入试验剂量,对热释光峰计数进行归一化处理,消除了热释光探测器剂量响应差异的影响,优化了现行热释光剂量的测量流程。配合简易辐照装置,使用优化测量流程和现行一般测量流程对同一批辐射环境监测的热释光剂量计进行测量,两者剂量值相对误差处于±5%以内,能够满足热释光剂量计在个人或环境电离辐射剂量监测过程中的准确度要求。并且优化后的热释光剂量测量流程无需均匀性筛选,降低了探测器均匀性性能要求,提升了测量流程的适用性,为中国的个人或环境剂量监测提供了一种高精度、高效率、低成本的测量方法。

使用热释光探测器进行辐射剂量监测是目前中国个人或环境剂量监测的主要方法之一。为解决热释光探测器在使用前需进行均匀性筛选以及测量过程复杂的问题,通过引入试验剂量,对热释光峰计数进行归一化处理,消除了热释光探测器剂量响应差异的影响,优化了现行热释光剂量的测量流程。配合简易辐照装置,使用优化测量流程和现行一般测量流程对同一批辐射环境监测的热释光剂量计进行测量,两者剂量值相对误差处于±5%以内,能够满足热释光剂量计在个人或环境电离辐射剂量监测过程中的准确度要求。并且优化后的热释光剂量测量流程无需均匀性筛选,降低了探测器均匀性性能要求,提升了测量流程的适用性,为中国的个人或环境剂量监测提供了一种高精度、高效率、低成本的测量方法。

Radiation dose monitoring using thermoluminescent detectors is currently one of the main methods of personal or environmental dose monitoring in China. In order to solve the problem of uniformity screening before the use of thermoluminescent detector, and the complexity of the measurement process. Test dose and thermoluminescent peak counts normalization were used to optimize the measurement process of thermoluminescent detectors. With the simple irradiation device, the same batch of thermoluminescent dosemeters for radiation environment monitoring were measured using the optimized and general measurement processes. The relative error of the dose values of the two was within ±5%, which satisfied the accuracy requirements of thermoluminescent dosemeters in the process of monitoring the dose of ionizing radiation to the individual or the environment. The results show that the optimized thermoluminescent dosimetry process reduces detector uniformity performance requirements and improves the applicability of the process. It provides a high-precision, high-efficiency and low-cost measurement method for personal or environmental dose monitoring in China.

随着核工业体系的快速发展,核技术已经广泛应用在能源、医疗、工业、农业等领域中。对人员和环境的辐射剂量监测,是保障公众/职业人员辐射安全的重要手段[1-5]。目前,在职业照射防护、个人/环境剂量监测等领域,主要使用热释光/光释光探测器进行剂量监测[6-7]。北京解放军防化研究院生产的LiF(Mg、Cu、P)材质的GR200A型热释光探测器,因其能量响应较好、灵敏度高、量程范围宽和易于测量、价格低廉等优点,在中国个人和环境辐射监测领域得到广泛应用[8-10]。
现有热释光剂量测量流程按照GB/T 10264—2014《个人和环境监测用热释光剂量测量系统》标准中对变异系数的要求,在使用之前对探测器进行一致性检定。变异系数合格的热释光探测器再使用标准辐照装置辐照刻度剂量计算该批热释光探测器的刻度因子[11-12]。上述两个步骤对热释光剂量监测起到了严格校正的作用,但筛选过程会淘汰一部分热释光探测器造成监测成本升高、资源浪费。刻度过程需使用标准辐照装置且测量过程复杂,考虑到使用效率与安全性,辐射监测部门难以配备标准辐照装置。此外,若热释光探测器在剂量监测过程中剂量响应发生变化,依据原有的刻度因子将无法得出准确的辐射剂量监测结果[13]。
针对热释光剂量测量流程存在的问题,现通过分析热释光探测器的热释光特性,对现有的热释光剂量测量方法展开优化研究,并对优化后的测量流程进行效果验证。
1 热释光探测器性能分析
收起
GR200A热释光探测器主要依靠热释光磷光体储存所接收的辐射剂量[14],但由于在生产、加工过程中,难以保证不同批次热释光探测器之间的热释光磷光体浓度的一致性,从而导致不同探测器的剂量响应可能存在差异[13,15]。因此,热释光探测器在使用前需要经过均匀性筛选,满足变异系数指标要求后进行刻度获得该批热释光探测器的刻度因子才能用于辐射剂量监测[16]。
1.1 稳定性测试
随机选取同一批次4个GR200A热释光探测器进行稳定性测试,退火后使用90Sr/90Y β源辐照0.2 Gy,并进行热释光测量,连续循环10次,统计每次测量所得到的热释光峰计数,对热释光探测器在重复测量过程中热释光峰计数的稳定性进行评价,测量结果如图1所示。连续10次测量所得出的热释光峰计数波动较小,4个热释光探测器热释光峰计数的变异系数分别为1.63%、0.78%、0.87%和2.49%,热释光剂量计的计数在10次重复测量过程中几乎未发生变化,能够满足热释光探测器对个人/环境剂量测量的稳定性要求。
1.2 剂量线性
选取不同批次的4个GR200A热释光探测器进行退火。随后,对每个热释光探测器依次使用 90 S r / 90Y β源辐照0.1~1 Gy,且重复10次,每次循环增加0.1 Gy。辐照完成后,进行热释光测量并统计热释光峰计数,结果如图2所示。测量结果表明,当热释光探测器使用90Sr/90Y β源辐照0.1~1 Gy时,热释光峰计数与所接受的辐照剂量具有较高的线性相关性,二者的线性相关性R2均优于0.99。
1.3 剂量响应差异
随机选取未经均匀性筛选的不同批次的16个GR200A热释光探测器,退火后对所选取的热释光探测器使用90Sr/90Y β源辐照相同剂量,并进行热释光测量,统计其热释光峰计数,结果如图3所示。不同热释光探测器之间剂量响应差别较大,变异系数达到14.16%,不同批次之间的热释光探测器无法混合使用,直接使用会导致剂量监测结果的准确度降低。按照现有测量流程中对热释光探测器变异系数低于5%的要求[16],上述热释光探测器将不能用于辐射剂量的监测,在一定程度上增加了使用热释光探测器进行个人/环境辐射剂量的监测成本。
2 热释光剂量测量流程优化
收起
2.1 优化的理论基础
热释光探测器的应用需要定量确定探测器的热释光峰计数与剂量值之间的关系,这一过程称为刻度。剂量值D的计算公式为
D = L k
式(1)中:L为热释光峰计数;k为刻度因子。
对于不同批次热释光探测器,磷光体浓度差异是导致探测器之间剂量响应差异的主要原因,即刻度因子k的不同。在GR200A热释光探测器良好的稳定性及剂量线性响应能力的基础上,可通过采用热释光峰计数归一化方法降低不同热释光探测器之间的剂量响应差异,使不同批次热释光探测器能够满足个人/环境剂量监测中对热释光探测器变异系数的测量需求。热释光峰计数归一化是指在待测剂量DL的基础上,再对热释光探测器辐照一个较小的试验剂量DT。
D L D T = L k T k
式(2)中:T为试验剂量的热释光峰计数。
D L = L T D T
相比于常规方法中使用的热释光峰计数,L/T仅与热释光探测器的剂量线性有关,与热释光探测器所含磷光体浓度无关,使用L/T进行归一化能够消除不同热释光探测器之间因所含磷光体浓度差异引起的剂量响应差异。
选取40个不同批次的GR200A热释光探测器,使用90Sr/90Y β源依次辐照0.2 Gy的人工剂量与0.1 Gy的试验剂量并测量其对应的热释光峰计数,以及计算热释光峰计数归一化均匀性筛选方法所需的L/T。两种热释光剂量计均匀性筛选方法的对比结果如图4所示,原有热释光探测器均匀性筛选方法下该组热释光探测器对应的变异系数为18.68%,而热释光峰计数归一化的均匀性筛选方法所对应的变异系数为3.02%,远低于个人/环境剂量监测中对热释光探测器变异系数的测量需求。
两种热释光探测器均匀性筛选方法表明当采用热释光计数归一化方法进行辐射剂量测量时,能够去除热释光探测器之间因磷光体浓度差异所引起的剂量响应差异,若不同批次热释光探测器的热释光峰计数与剂量之间均具有良好的剂量线性响应,热释光探测器之间的变异系数必然能够满足个人/环境剂量监测的测量需求。因此,热释光峰计数归一化方法的引入能够降低不同批次热释光探测器之间因剂量响应差异带来的影响,降低监测成本,提升热释光剂量计在个人/环境剂量监测中的准确性。
2.2 测量流程优化
中国现阶段广泛使用的GR200A热释光探测器在进行个人/环境辐射剂量测量时,现有的常规测量流程如表1所示。常规测量流程中除均匀性筛选流程造成热释光辐射剂量监测成本升高,操作复杂外,在常规测量流程中获取的热释光探测器刻度因子的使用范围仅适用于热释光剂量计在刻度后,其剂量响应没有发生变化的前提下使用。一旦在监测周期内或监测结果测量时热释光探测器受到周围环境中温度、湿度和测量温度等因素影响[13],剂量响应发生变化,则前期获取的刻度因子将带入较大误差,导致无法准确获取监测剂量值。
以现有的GR200A热释光探测器辐射剂量测量流程中存在的问题为出发点,引入热释光峰计数归一化的测量方法,对现有的测量流程做出相应的优化。优化后的热释光剂量计测量流程如表1所示,直接对热释光探测器辐照一个固定的试验剂量DT,对其进行等效剂量测量得到准确剂量值。在电离辐射监测完成之后辐照同样的试验剂量DT,根据L/T计算出热释光探测器所接受电离辐射的总剂量DL。优化后的方法省略了剂量计筛选的环节,L/T因为与热释光剂量计的剂量响应无关,只要试验剂量DT不变,仅需刻度一次,所有热释光探测器均可使用,即使在辐射监测过程中由于其他因素影响导致的热释光探测器剂量响应变化,也能准确地测量出电离辐射剂量。
2.3 试验剂量辐照装置
优化后的测量流程需要辐照一个固定的试验剂量,因此设计了一套试验剂量辐照装置,本装置主要由放射源、散射腔、准直器、屏蔽室、热释光托板、低转速电机、弧形衰减器组成,结构如图5所示。参考辐射场中的热释光探测器吸收剂量的蒙特卡罗模拟结果显示,散射射线贡献率为照射野范围剂量平均值的0.97%,满足相关标准要求。热释光托盘的直径100 mm,样品位置最外层直径62.2 mm,分为6圈,共计能够辐照91个样品。辐照装置实物图如图6所示。
选取30片热释光探测器均匀放置于热释光托盘中,除中心点外每圈均匀放置6片热释光剂量计,重复辐照5次并测量其热释光峰计数。结果显示,同圈热释光探测器的热释光峰计数不均匀性小于3%,满足需求。
3 效果验证
收起
通过对四川省辐射环境管理监测中心站(以下简称辐射监测站)的一批环境辐射监测热释光剂量计使用两种测量流程进行测量,来验证本研究所优化的热释光剂量测量流程的效果。每一个监测点位的热释光剂量计分为两部分:一部分使用优化测量流程测量,另一部分由辐射监测站使用现有测量流程进行测量。
首先在辐照装置中对热释光探测器辐照试验剂量DT,送往辐射监测站进行等效剂量测量,获得其准确剂量值。对采用优化测量方法的热释光剂量计进行测量并统计热释光峰计数L;退火后对其辐照同一试验剂量DT,测量并统计热释光峰计数T。依据L与T的比值,计算出该批热释光剂量计在环境剂量监测过程中所接受的电离辐射剂量,与辐射监测站采用常规流程测量的另一批热释光剂量计剂量值进行对比,如表2所示。结果显示,优化后的测量流程的测量值与辐射监测站的测量值相比较,同一地点的热释光剂量计测量结果的相对误差均处于±5%以内,基本处于同一水平。优化流程测量值的变异系数小于5%,满足电离辐射环境监测要求。
4 结论
收起
通过引入试验剂量,采用热释光峰计数归一化方法,能够消除探测器之间剂量响应差异给测量结果带来的影响,实现热释光探测器无需进行均匀性筛选即可用于电离辐射剂量监测。在此基础上优化的热释光剂量测量流程,使热释光探测器即便在监测周期内或监测结果测量的过程中因受周围环境因素影响导致自身剂量响应发生变化的情况下,仍能准确地测量出监测对象的剂量值。优化测量流程在保证辐射剂量监测的准确度的情况下,可以降低相关企业/监管部门对于辐射监测的成本投入,简化了热释光辐射剂量监测流程。这种高精度、高效率、低成本的热释光剂量测量方法,有效提升中国热释光剂量监测水平,为中国热释光剂量监测领域提供新的技术支持。
