Optically Stimulated Luminescence (OSL) Dosimetry Service

First and Only Optically Stimulated Luminescence (OSL) Dosimetry Service

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. 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.

Benefits at a Glance

Using Landauer’s proprietary Optically Stimulated Luminescence (OSL) technology, TÜV Rheinland’s Dosimetry Service assures that your dose reports are on time and accurate.

Fast issuance of dose reports

OSL dosimeters are measured for only 12-15 seconds per badge. As a result, your dose reports will be available in less than 14 working days after we have received your badges.

Reliability of results (Calibration is traceable to NIST)

Our calibration equipment is traceable to the National Institute of Standards and Technology (NIST) located at Maryland, USA. NIST is an affiliated member of the IAEA / WHO Primary Standard Dosimetry Laboratory (PSDL) Network.

Data Archiving

Dose assessments are automatically saved to multiple devices to ensure that your results are available anytime when you need them.

Frequently Asked Questions

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.

What is the OSL dosimeter called?

TÜV Rheinland Philippines are 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.

How are OSL dosimeters measured?

OSL dosimeters are retrieved after one to two months. After receiving the dosimeters, they will be inspected for any damage. Then, the dosimeters will be stored in a shielded container until its scheduled date of measurement. After storage, the dosimeters will be measured using the Microstar© OSL Dosimeter Reader from Landauer, Inc., The reader stimulates the (Al2O3:C ) material with green light from a light emitting diode source. After stimulation, the Al2O3 emits blue light, which is proportional to the radiation exposure absorbed by the material. The blue light is absorbed by the photo multiplier, which converts the photons to an electrical signal. After measuring the dosimeters, they are annealed or “bleached” to erase the absorbed dose from the previous monitoring period.

What are the advantages of OSL dosimeters over TLD and Film badge?

Since OSL is the most advanced technology in radiation monitoring, it offers several advantages such as fast dose assessment, dosimeter archiving, non-destructive readouts, high degree of environmental stability and much more.

When and how are the dose reports issued?

After receiving the OSL dosimeters from your facility, your dose reports will be available in less than 14 working days. The reports can be delivered through mail, email or fax.
