The treatment with high doses of ionizing radiation is prescribed for the terminal sterilization of many healthcare products. In order to check the product irradiation, it may be useful to develop suitable detection methods. The aim of this work was to verify the suitability of the thermoluminescence (TL) and electron paramagnetic resonance (EPR) techniques to reveal illegal omission of radiation sterilization in glass used for blood test tubes. In particular, this work reports the results of the analysis performed on two batches of glass tubes provided by the same manufacturer. The results indicated that both TL and EPR techniques could reveal the damage induced by high doses of ionizing radiation in the glass allowing the identification of the tubes which were irradiated at the manufacture stage. The study provided also some information about the chemical composition of the two-batch glass.
高剂量电离辐射处理被规定用于许多医疗保健产品的最终灭菌。为了检查产品的辐照情况，开发合适的检测方法可能会很有用。这项工作的目的是验证热释光（TL）和电子顺磁共振（EPR）技术是否适用于揭示用于血液试管的玻璃中非法遗漏辐射灭菌的情况。特别是，这项工作报告了对同一制造商提供的两批玻璃管进行分析的结果。结果表明，TL和EPR技术都能揭示高剂量电离辐射在玻璃中引起的损伤，从而能够识别在制造阶段接受过辐照的试管。该研究还提供了有关这两批玻璃化学成分的一些信息。
