Which dosimeter type is known for its higher sensitivity to radiation?

The Optically Stimulable Luminescent dosimeter (OSL) is recognized for its higher sensitivity to radiation, which greatly enhances its utility in various radiation monitoring applications. OSL materials, such as aluminum oxide, can detect a wide range of radiation types, including gamma and X-rays, with great precision. When exposed to radiation, these materials store energy, which can later be released as light when stimulated by a laser. This characteristic allows OSLs to provide accurate and precise measurements of radiation exposure even at low dose levels.

In addition to their increased sensitivity, OSLs also benefit from the ability to be reanalyzed, meaning they can be read multiple times, thereby enhancing their functionality in monitoring dose over time. This reusability, combined with their superior performance in low-dose environments, makes OSL dosimeters particularly advantageous in occupations where workers are exposed to varying levels of radiation and where precise dose management is critical for safety.

Other dosimeter types, like film badges, thermoluminescent dosimeters (TLD), and ionization chambers, have their own unique advantages and use cases, but they generally do not match the sensitivity levels of OSL dosimeters in detecting low radiation doses.
