Area dosimetry in the Praid-salt mine.

Area of Science:

• Radiation detection and measurement
• Environmental monitoring
• Applied physics

Background:

• Accurate measurement of ultra-low radiation levels is crucial for sensitive applications.
• Traditional methods may lack the sensitivity required for characterizing specific environments.
• The Romanian thermoluminescent dosimetry system offers a potential solution for these challenges.

Purpose of the Study:

• To present a specialized application of the Romanian thermoluminescent dosimetry system.
• To measure ultra-low-level ambient dose equivalent rates (1-100 nSv/h).
• To characterize a Romanian salt mine for potential use as an underground accelerator laboratory.

Main Methods:

• Utilized LiF:Mg,Cu,P (GR-200A) detectors for thermoluminescence measurements.
• Detailed experimental procedures and necessary corrections for ultra-low-level measurements.
• Employed gamma-ray spectrometry for comparative analysis.

Main Results:

• Successfully measured ultra-low ambient dose equivalent rates in the specified range.
• Characterized the radiation background of a Romanian salt mine.
• Validated results through comparison with previous measurements and gamma-ray spectrometry.

Conclusions:

• The Romanian thermoluminescent dosimetry system reliably measures ultra-low radiation background.
• The characterized salt mine is suitable for potential underground laboratory applications.
• The system demonstrates high accuracy and effectiveness in sensitive radiation monitoring scenarios.
