Summary
This study investigated imaging plates (IPs) performance at low temperatures. IPs function properly below 0°C, with no fading observed at -80°C, though sensitivity decreases due to thermostimulated luminescence.
Area of Science:
- Radiation detection and dosimetry
- Materials science
Background:
- Imaging plates (IPs) are crucial for radiation detection.
- IP performance at sub-zero temperatures remains largely uncharacterized.
Purpose of the Study:
- To evaluate the fundamental properties and performance of IPs at temperatures ranging from -80°C to 30°C.
- To investigate the impact of low temperatures on IP response, fading, and sensitivity.
Main Methods:
- Irradiation of an IP with gamma rays from monazite at controlled temperatures (-80°C to 30°C).
- Analysis of IP response linearity with irradiation time.
- Measurement of fading and photostimulated luminescence (PSL) values.
- Investigation of thermostimulated luminescence (TSL) effects.
Main Results:
- IP response was linear with irradiation time, indicating proper function at low temperatures.
- No fading was observed at -30°C and -80°C.
- The fading-corrected PSL value was lower at -80°C compared to higher temperatures due to TSL.
- A significant TSL peak at approximately -43°C explained reduced sensitivity at -80°C.
Conclusions:
- IPs are functional at sub-zero temperatures, with no fading below 0°C.
- Thermostimulated luminescence at low temperatures, particularly around -43°C, reduces apparent IP sensitivity.
- Quantitative measurements using IPs at -80°C require correction for this observed low sensitivity.
