Summary
A new portable thermoluminescent dosimeter system accurately measures cosmic radiation doses on spacecraft. This robust system is designed for spaceflight, offering reliable space radiation monitoring.
Area of Science:
- Space Science
- Radiation Detection
- Instrumentation
Background:
- Space missions require accurate measurement of cosmic radiation doses.
- Existing dosimetry systems may lack portability or robustness for spacecraft environments.
- Understanding radiation exposure is critical for astronaut safety and mission planning.
Purpose of the Study:
- To develop a compact, portable, and rugged thermoluminescent dosimeter (TLD) system for measuring cosmic radiation on spacecraft.
- To detail the construction and technical specifications of the TLD reader and dosimeter components.
Main Methods:
- Development of a small, battery-operated reader integrated with a specialized bulb dosimeter.
- Design focused on vibration and shock resistance for spaceflight conditions.
- Characterization of the system's measurement range and technical parameters.
Main Results:
- A functional TLD system was successfully developed, demonstrating portability and resistance to environmental factors.
- The system can measure radiation doses ranging from 10 microGy to 100 mGy.
- The reader exhibits low power consumption (approx. 5 W), compact volume (approx. 1 dm3), and light mass (approx. 1 kg).
Conclusions:
- The developed thermoluminescent dosimeter system is suitable for measuring cosmic radiation doses in spacecraft.
- Its portable, robust design and wide measurement range make it a valuable tool for space radiation dosimetry.
- Further details on construction and technical parameters are provided for potential implementation.
