Which radiation monitoring device uses aluminum oxide to absorb and store x-ray energy?

The optically stimulated luminescent dosimeter (OSL) is the device that uses aluminum oxide to absorb and store x-ray energy. In OSL, when aluminum oxide is exposed to ionizing radiation, it traps some of the energy within its structure. Later, this stored energy can be released by stimulating the aluminum oxide with a specific light source, resulting in luminescence. The amount of light emitted is proportional to the amount of radiation exposure and can be measured to determine the dose.

This method offers several advantages, including improved sensitivity and the ability to re-read or assess the stored dosimetry multiple times without destroying the sample. This provides valuable information about radiation exposure in various settings, making it a popular choice for radiation monitoring among healthcare professionals and workers in radiation-related fields.
