Thermoluminescent Dosimeter (TLD) Chips are advanced solid-state radiation detectors designed to accurately measure ionizing radiation by storing absorbed energy within the crystal lattice and releasing it as light when heated. This thermoluminescence principle enables highly precise and reliable dose measurement across a wide range of radiation monitoring applications.
CQT GROUP supplies high-performance LiF:Mg,Cu,P Thermoluminescent Dosimeter Chips (GR-200 Series) featuring exceptional sensitivity, excellent tissue equivalence, low detection thresholds, and outstanding dose linearity. These characteristics make them ideal for personal dosimetry, environmental radiation monitoring, medical physics, nuclear power plants, research laboratories, and homeland security applications.
Thermoluminescent Dosimeter Chips operate by absorbing energy from ionizing radiation such as X-rays, gamma rays, beta particles, or other radiation sources. The absorbed energy is trapped within the crystal structure of the detector material.
During the readout process, the chip is heated in a TLD reader, causing the trapped electrons to return to their normal state and emit visible light. The intensity of the emitted light is directly proportional to the absorbed radiation dose, allowing for precise quantitative measurement.
This passive detection method provides excellent long-term stability and does not require an external power source during radiation exposure.
