What is the minimum exposure TLDs can measure?

The minimum exposure that Thermoluminescent Dosimeters (TLDs) can accurately measure is typically around 100 microGy. TLDs work by absorbing energy from ionizing radiation, which is then released as light when heated. The amount of light emitted is proportional to the dose of radiation received. The sensitivity and the range of TLDs depend on their specific design and the type of radiation they are measuring. While some advanced or specialized TLD systems may detect lower doses, the standard TLDs primarily used in monitoring radiation exposure have a detection threshold at or around 100 microGy. This measurement capability allows them to be effective in monitoring occupational exposure levels for workers in environments with potential radiation hazards, ensuring that safety regulations are met. Measurements lower than this threshold may not provide reliable data due to background noise or insufficient sensitivity of the detectors, which emphasizes the importance of understanding the capabilities of the dosimeter in radiation safety practices.
