About OSL Badges from Radiation Detection Company

Precise Re-Readable Dose Readings

Our OSL dosimeter stands out as a reliable and accurate solution for monitoring radiation exposure. We designed our OSL badge to be tissue equivalent and provide precise dose readings essential for medical practitioners and technologists.

The OSL dosimeter’s lightweight and durable construction ensures it can withstand various environmental conditions such as moisture and extreme temperatures. An OSL is a smart choice for a wide range of applications, including veterinarians, dentists, chiropractors, and anyone at risk of occupational X-ray and gamma exposure.

Employees can wear an OSL badge in multiple configurations for whole body, fetal, or area monitoring with flexibility to meet various needs.

We can re-read the OSL dosimeter badge multiple times and archive the dosimeter for later reanalysis, adding an extra layer of verification to ensure wearers can trust their reported doses.

Frequently Asked Questions

Curious About RDC’s OSL Dosimeter?

Find answers to common questions about our OSL badge.

How does an OSL dosimeter work?

Our OSL dosimeter measures radiation exposure using beryllium oxide to store energy when exposed to radiation. The material traps electrons in higher energy states, then a light source stimulates the electrons to release the energy during processing and emit light. We measure the intensity of this light, which is proportional to the radiation dose, to determine the amount of exposure. OSL dosimeters can be re-read multiple times for verification and archival purposes.

Unlike single-use TLD badges, OSL dosimeters can be re-read multiple times for dose verification. OSLs are highly sensitive to low radiation levels and resistant to extreme temperatures and moisture. They can be worn for up to a year with minimal signal fade, whereas organizations typically use TLDs for shorter monitoring periods.

OSL dosimeters require a light source for reading the dose, while TLDs require heat for processing. Digital dosimeters, on the other hand, provide real-time readings.

OSL dosimeters can measure photon energies ranging from 12 keV to 7 MeV. This makes them suitable for detecting X-ray and gamma radiation across a wide spectrum of energy levels.

OSL dosimeters are known for their high accuracy and precision in radiation dose measurement. They can accurately measure doses with a minimum reportable dose of 10 mrem (0.1 mSv) and a lower limit of detection of 1 mrem (0.01 mSv). Their precision and ability to be re-read multiple times without significant signal degradation contribute to reliable and consistent dose measurements.

After you return your OSL dosimeters to RDC, we’ll process each badge using specialized readers to stimulate the dosimeter material with light, causing it to emit luminescence proportional to the radiation dose absorbed. We’ll measure the emitted light and convert the data into a dose reading, then compile detailed reports, which will be mailed and made available online within 10 business days of receipt of the badges.
