Abstract The thermoluminescence of different chip cards was measured and analyzed for emergency dosimetry. Three SIM cards that are commonly found in mobile communication providers in South Korea and three smart IC cards that can be purchased online were used for the experiment. Chemical element analysis based on EDS mapping images was carried out and different weight percent of silica was found for each chip card. Glow curves of radiation induced signals through different combinations of optical filters showed blue or red emissions depending on chip cards. Sensitivity change resulting from the thermal stimulation was found to be 1.8 ± 0.27 and 0.5 ± 0.06 for the blue and red emission, respectively. In addition, signal fading resulted in more than 20% of the initial signal remaining 20 days after irradiation, when the 100–150 °C signal is used. Furthermore, the dose response was recorded from 50 mGy to 10 Gy for each chip card.

应急剂量测定用芯片卡的热释光特性

摘要 对不同芯片卡的热释光进行了测量和分析，用于应急剂量测定。实验使用了韩国移动通信提供商常见的三张 SIM 卡和三张可在线购买的智能 IC 卡。进行了基于 EDS 映射图像的化学元素分析，发现每张芯片卡的二氧化硅重量百分比不同。通过不同滤光片组合的辐射感应信号的辉光曲线显示出蓝色或红色发射，具体取决于芯片卡。发现热刺激引起的灵敏度变化对于蓝色和红色发射分别为 1.8 ± 0.27 和 0.5 ± 0.06。此外，当使用 100–150 °C 信号时，信号衰减导致超过 20% 的初始信号在辐照后 20 天仍然存在。
