Summary: Scintillation detectors are crucial for radiation measurement, but their calibration can be a challenge, particularly when full-energy peaks are not distinct. Researchers have developed a new calibration technique called the ‘convolution model’ to address this issue by accurately representing the Compton edge. This method has been successfully applied to different detectors such as the plastic scintillator BC408, NaI crystal, and LaBr\(_3\) crystal using \({}^{137}\)Cs radioactive sources.

Key Points:

• The new calibration method, ‘convolution model,’ provides accurate calibration without depending on full-energy peaks.
• Tested on various detectors, demonstrating errors within 1% compared to full-energy peak calibration.
• Potentially beneficial for plastic scintillators where full-energy peaks might not be prominent.

Importance: The convolution model enables more precise and efficient calibration of scintillation detectors. This methodology can be particularly significant in fields where radiation detection plays a critical role, such as nuclear medicine, environmental monitoring, and security applications. Better energy resolution and accuracy could lead to advancements in these areas and contribute to enhanced safety measures. Read more
