Thermoluminescence Dosimetry
Materials
Lithium Fluoride finds use in medical physics dosimetry due to its effective atomic number of 8.2, negligible fading and usable range from a few mR to 500R. Standard response is ±30% per batch.
Lithium Fluoride, High Sensitivity - High sensitivity manganese, copper and phosphorous doped LiF dosimeters exhibit the same desirable properties as TLD-100, but feature sensitivity 15 times greater. Standard response is ±15% per batch.
Calcium Fluoride - Dysprosium-activated calcium fluoride dosimeters exhibit sensitivity 30 times greater than lithium fluoride (TLD-100) and three times that of manganese-activated CaF. They are considered the best material for short-term environmental applications. The effective atomic number for photoelectric absorption is 16.3. Standard response is ±30% per batch.
Aluminum Oxide dosimeters have sensitivity 50 times greater than TLD-100 and an effective atomic number for photoelectric absorption of 10.2. These properties make them well suited for personnel dosimetry applications that require detectability of low radiation levels, low long-term fading and more nearly tissue-equivalent performance than calcium-based materials. Standard response is ±30% per batch.
