Basic Performance Evaluation of a Radiation Survey Meter That Uses a Plastic-Scintillation Sensor.

Area of Science:

• Nuclear instrumentation
• Radiation detection
• Environmental monitoring

Background:

• Geiger-Müller (GM) survey meters are standard for beta-ray measurement.
• A novel plastic-scintillation survey meter has been developed.
• Performance data for commercial plastic-scintillation meters are lacking.

Purpose of the Study:

• To experimentally compare the performance of plastic-scintillation and GM survey meters.
• To evaluate the accuracy and reliability of plastic-scintillation survey meters.
• To assess their suitability for beta-ray measurement and monitoring.

Main Methods:

• Experimental comparison of plastic-scintillation and GM survey meters.
• Performance evaluation under varying radiation count rates.
• Analysis of count loss and accuracy at high and background radiation levels.

Main Results:

• Both survey meters showed similar performance at background radiation rates.
• GM survey meters exhibited count losses at high radiation rates.
• Plastic-scintillation survey meters maintained accuracy with minimal count loss at high rates.

Conclusions:

• Plastic-scintillation survey meters are less affected by count loss than GM survey meters.
• They offer a significant advantage in high radiation environments.
• Plastic-scintillation survey meters are a useful instrument for beta-ray measurement and monitoring.
