    • To describe the functionality of the automated reader and its calibration source.

    Main Methods:

    • Development of an automated TLD reader system.
    • Utilizing Lithium Fluoride (LiF) as the dosimeter material, sealed in thin-walled Teflon tubes.
    • Employing a (90Sr-90Y) calibration radiation source for dosimeter calibration.
    • Individual dosimeter identification using numerical labels.

    Main Results:

    • Successful development and construction of an automated TLD reader.
    • Demonstration of simplified individual calibration procedures.
    • Description of the operational principles of the reader and calibration source.

    Conclusions:

    • The automated TLD reader offers a streamlined approach to radiation dosimetry.
    • The system facilitates accurate and efficient individual calibration of LiF dosimeters.
    • This technology enhances the reliability and ease of use in radiation monitoring.
