Providing you reliable, timely and more efficient OSL Dosimetry Services with health and safety in mind.

Optically Stimulated Luminescence or OSL is the most advanced technology developed by Landauer, Inc. for measuring radiation exposure. Compared to thermoluminescence 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.

With the on-going community quarantine, our courier partner has updated their service level lead time with additional 5-10 days within NCR; 6-9 days to Luzon; 8-12 days to Visayas and 10-14 days to Mindanao.

To effectively provide the highest possible levels of health protection to our staff and other visitors within TÜV Rheinland Philippines Offices, the following health and safety protocols are currently enforced that may entail additional time and steps.

For badges that had been due for return between March 16 up to May 16, your wear period has been automatically extended. Contact your Account Management RepresenTative for this.

To ensure timeliness of dose reports needed for your timely submission of your facility’s renewal – a timely return of OSL Badges within the prescribed period to TÜV Rheinland Philippines Makati will help.

We remain committed in sending you dose reports within the service level time upon receiving your returned badges.  We send out electronic copies of your dose report to your registered email address with us and do check if if this goes to your spam or archived folders of your emai linbox.

TÜV Rheinland Philippines offers InLight whole body dosimeters for radiation workers. This dosimeter can be placed 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.

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 comes with badge holder that protects the dosimeter from different environmental conditions 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.

OSL dosimeters are retrieved after one to two months. After receiving the dosimeters, they will be inspected for any tampering or 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 an industrial-grade auto-reader. 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.

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.

After receiving the OSL dosimeters from your facility, your dose reports will be available in less than 15 working days. The reports can be delivered through e-mail and mail.
