OSLdosimetrejä

OSL dosimetrejä, or Optically Stimulated Luminescence dosimeters, are passive devices used to measure ionizing radiation exposure. They consist of a material, typically a phosphor, that stores energy when exposed to radiation. This stored energy can be released and measured as light when the dosimeter is stimulated by a laser or LED. The intensity of the emitted light is proportional to the amount of radiation absorbed.

These dosimeters are widely employed in radiation protection for personnel monitoring in various environments, including hospitals, nuclear power plants, and research laboratories. Their advantages include a wide dynamic range, the ability to measure low doses, and reusability after reading. OSL dosimeters can record dose over extended periods, making them suitable for routine occupational exposure assessment. The reading process is non-destructive, allowing for re-analysis if necessary. Different phosphor materials are used depending on the type and energy of the radiation being measured. The data obtained from OSL dosimeters is crucial for ensuring the safety of individuals working with or around sources of ionizing radiation and for compliance with regulatory requirements.
