What type of dosimeter is known for its ability to be sensitive to low levels of ionizing radiation?

The Optically Stimulable Luminescent Dosimeter (OSL) is recognized for its sensitivity to low levels of ionizing radiation, making it an excellent choice for monitoring radiation exposure in various environments, including those where exposure levels can be very low. OSL dosimeters work by using materials that emit light when stimulated by a laser, providing a measurement of the radiation dose that is both accurate and precise. The ability to detect even minimal amounts of ionizing radiation is crucial for safety in environments where radiation exposure is a concern.

OSL dosimeters also offer advantages such as re-reading capabilities, which allow for the potential of reassessing the dose after initial measurement without needing to replace the dosimeter itself. Their sensitivity, combined with this capability, makes them particularly useful for personnel who might encounter varying levels of radiation exposure over time.
