Investigation of Gamma Radiation Effects on the Resistance of Some Types of Lamps in Active Power Mode

Abstract

This study aims to investigate the effects of gamma radiation on some various lamp types while they are operating in active power mode. The gamma radiation can degrade electronic devices, and understanding its influence on the lamp's functionality is critical for applications in high-radiation environments. This research quantifies the radiation resistance thresholds of incandescent, fluorescent, and other lamps. The objectives are to determine the gamma radiation levels lamps can withstand before exhibiting performance declines, identify the physical and chemical changes in the lamp components caused by radiation exposure, and develop strategies to enhance lamp radiation hardness. The methodology utilizes controlled radiation sources Co-60, to expose lamps to increasing dosages while monitoring electrical and photometric parameters. Moreover, materials analysis and integrity assessments will also be conducted. Quantitative performance data will be used to identify vulnerable lamp components and correlations between design factors and radiation resistance. The findings will help guide the development of lighting solutions tailored for high-reliability operation in the presence of gamma radiation. LED bulbs exhibited remarkable resilience to gamma exposure. Only a 5% reduction in luminance was noted at 100 kGy, indicating a high level of radiation hardness. The comparison illustrates that LED bulbs maintain performance closest to control samples, followed by incandescent bulbs. CFLs and OLED panels are more susceptible to gamma radiation-induced degradation.
