ISO 12794 Passive Personal Dosimetry with TLDs
Passive personal dosimetry using thermoluminescent dosimeters (TLDs) is a critical component in radiation protection programs, particularly where workers are exposed to ionizing radiation. This method involves the use of small TLD badges that can be worn by individuals to measure absorbed dose over time. The ISO 12794 standard provides guidelines for passive personal dosimetry using TLDs, ensuring accuracy and reliability across various applications.
Understanding the nuances of this technology is essential for those involved in nuclear and radiation-related industries. Compliance with ISO standards ensures that the dosimeters used are accurate, reliable, and meet international benchmarks. The standard covers a range of topics including the design, calibration, use, and interpretation of TLDs.
The process begins with the selection of appropriate TLD badges based on the expected dose levels and application environment. Proper placement is crucial to ensure that the dosimeters accurately represent the radiation exposure received by the individual. Calibration ensures the accuracy of the dosimeter readings, which is a fundamental requirement for compliance with regulatory standards.
After use, the dosimeters are retrieved and sent for analysis in our laboratory, where we specialize in providing accurate readouts of absorbed dose. The results are then reported to the client, along with recommendations for further action if necessary. This service is particularly important for industries such as nuclear power generation, medical imaging, and industrial radiography.
The ISO 12794 standard emphasizes the importance of regular calibration and quality control checks to maintain the integrity of the dosimetry system. Regular audits and validation tests are also recommended to ensure that the dosimeters continue to meet the required standards over their operational life.
