Abstract Objective To assess the feasibility of employing chip resistors for retrospective dose reconstruction following nuclear accidents, to examine the effects of storage temperature and storage time on the optically stimulated luminescence (OSL) characteristics of the chip resistors, and to explore measures to mitigate these effects. Methods Chip resistors were analyzed using automated instruments for measuring thermoluminescence and OSL manufactured by Risø in Denmark with various parameters to understand the impact of storage temperature and storage time on OSL signals. Results The OSL signals of chip resistors exhibited exponential attenuation within 10 min after irradiation, and then stabilized (count change < 10%) within 2-7 days of storage. The chip resistors exhibited linear dose responses within 1-3 days of storage after 0.1-2 Gy irradiation. OSL signals diminished as the storage temperature increased. However, preheating at 130 ℃ for 1 min effectively eliminated the differences caused by temperatures between 25 ℃ and 45 ℃. Conclusion The OSL signals of chip resistors are influenced by storage temperature and storage time. When preheated at 130 ℃ for 1 min, chip resistors stored for 1-7 days and at 25-45 ℃ exhibited OSL signal errors of 10% or less. This result emphasizes the importance of preheating for measurements in practical applications, thus providing a scientific approach and a solid foundation for the use of chip resistors in retrospective dose reconstruction.
