TÜV Rheinland Philippines Inc., the pioneering third party certification body in the country, brings you another first – the Landauer proprietary Optically Stimulated Luminescence (OSL) Dosimetry Service. Known as the most advanced technology for measuring radiation exposure, OSL Dosimetry uses Aluminum Oxide (Al2O3:C) crystal detectors.
Our experts have answered some of the frequently asked questions about OSL by our customers:
What is OSL?
Optically Stimulated Luminescence or OSL is the most advanced technology developed by Landauer, Inc. for measuring radiation exposure. Compared to thermolumiscence dosimeters (TLD), which are heated to determine the radiation exposure, OSL dosimeters are exposed to a light source to obtain the amount of radiation absorbed by the dosimeter. OSL Dosimetry utilizes the detector material Carbon doped Aluminum Oxide (Al2O3:C) crystals produced by Landauer.
Using state of the art technology provided by Landauer, Inc., our laboratory utilizes the Microstar© OSL Dosimeter Reader which stimulates the (Al2O3:C)material with green light from a light emitting diode source. After stimulation, the (Al2O3:C) emits blue light which is proportional to the radiation exposure of the material.
What is the OSL dosimeter called?
TÜV Rheinland Philippines is offering the Inlight Whole Body dosimeters for radiation workers. This dosimeter can be placed in the in the neck area, abdomen area, and at the extremities. The OSL dosimeter responds to photon and beta radiations and is not sensitive to neutron radiation.
What are the different parts of the OSL Inlight dosimeter?
The OSL Inlight dosimeter consists of the (Al2O3:C) detector slide, which is inserted in a plastic case that contains the different filters of the dosimeter. It also have plastic holders that protects the dosimeter from different environmental conditions, a security pin that locks the dosimeter in place and a clip to position the dosimeter in the body. Each dosimeter has a unique barcode number, which is used to identify the dosimeter’s user, designation, facility, and monitoring period.
