A NEW TL-DOS NEUTRON DOSEMETER FOR MEASUREMENTS OF THE PERSONAL DOSE EQUIVALENT HP(10)

Area of Science:

• Radiation Detection and Measurement
• Dosimetry
• Thermoluminescence Technology

Background:

• Routine dosimetry requires accurate measurement of neutron and photon radiation doses.
• Existing thermoluminescence albedo dosemeters have limitations in sensitivity and detector lifespan.
• The TL-DOS project aimed to develop an improved radiation monitoring solution.

Purpose of the Study:

• To introduce a novel thermoluminescence albedo dosemeter (TL-DOS) with enhanced properties.
• To evaluate the performance of the TL-DOS neutron dosemeter through field measurements and calibrations.
• To compare the new dosemeter against established routine dosimetry systems.

Main Methods:

• Development of a new thermoluminescence albedo dosemeter.
• Testing and calibration of the dosemeter using known radiation fields.
• Comparative analysis with a currently used thermoluminescence albedo dosemeter in Germany.

Main Results:

• The TL-DOS dosemeter demonstrates the capability to measure both neutron and photon whole-body doses.
• The device shows potential for detecting high-linear energy transfer peaks.
• Improved detector sensitivity and extended detector lifetime were observed.

Conclusions:

• The developed TL-DOS thermoluminescence albedo dosemeter offers superior performance for radiation dosimetry.
• The dosemeter presents significant advantages over existing technologies for radiation worker monitoring.
• The findings support the adoption of the TL-DOS for routine dosimetry applications.
