Milad Daru Company TLD (Thermo Luminescent Dosimeter) Card is a type of detector used for radioactive radiation dose measurement. TLD Dosimeters measure ionizing radiation through the phenomenon of Thermoluminescence. where the irradiated material emits visible light upon thermal stimulation.

Here are some features and advantages of TLD :

• Reusable:   TLD dosimeters are depleted after reading the dose at a given time and can be used again for measurement. This particular feature allows multiple measurements to be made in a period of time.
• Resistant to environmental factors: Light، temperature and humidity Don’t affect the dosimeters. This feature makes these dosimeters used in different environmental conditions including in hot and humid areas
• Measuring range and accuracy: These dosimeters have a good sensitivity in low to high doses due to unsaturation. This feature makes these dosimeters used accurately in dosimetric applications.
• Appropriate medical and radiation treatment centers : These dosimeters are used in medical and radiation treatment centers to measure radiation doses, because they have high accuracy and reusability.
• Durability:  TLDs have a long shelf life and are used for a long time without degrading the quality of their measurement.
