Abstract :
Objective: The growing demand for safety in nuclear facilities necessitates continuous monitoring of radioactive particles in the air, both within and around nuclear sites. Meanwhile, potential nuclear incidents require global oversight. Silicon detectors play a vital role in nuclear and medical measurements, particularly in the precise detection of charged particles such as alpha and beta particles. Two common types of these detectors—Silicon Surface Barrier (SSB) detectors and Passivated Implanted Planar Silicon (PIPS) detectors—each offer unique advantages and limitations. This study investigates the structural and functional characteristics of these two detector types and provides a comprehensive comparison of their efficiency, stability under varying environmental conditions, and measurement accuracy.
Materials and Methods: The primary material in both SSB and PIPS detectors is silicon (Si14). A library-based method was employed to compare the properties of the two detectors, along with an exploration of the potential application of nanotechnology in their structures.
Findings: The results indicate that PIPS detectors, with their superior thermal and humidity stability, are more suitable for long-term applications. In contrast, SSB detectors excel in short-term, low-cost laboratory settings due to their high sensitivity and rapid response, offering advantages in specific use cases. This comparison can assist researchers in selecting the appropriate detector based on specific research needs and environmental conditions.
Conclusion: PIPS detectors represent a new generation of silicon detectors capable of enhancing the accuracy of radioactivity measurements in biological samples.
