Frequently Asked Questions

Curious About RDC’s TLD Ring Dosimeter?

Find answers to common questions about our TLD ring badge.

How does a TLD ring dosimeter work?

Our TLD ring dosimeter measures radiation exposure using thermoluminescent materials. When exposed to ionizing radiation, these materials trap electrons in an excited state. To measure the accumulated radiation dose, we heat your TLD ring in a specialized reader, releasing the trapped electrons and emitting light proportional to the radiation dose received. This process allows for precise measurement of radiation exposure to extremities.

We specifically engineered our TLD ring dosimeter for extremity monitoring due to its small, ergonomic form factor. You can comfortably wear the badge on your fingers or wrists, ensuring precise radiation dose measurements for these sensitive areas. The TLD ring is lightweight and unobtrusive, making it ideal for professionals who need to monitor radiation exposure without hindering their daily tasks. Wear your ring badge in addition to a whole body dosimeter for peace of mind and enhanced safety.

Our TLD dosimeter ring measures beta, gamma, and X-ray radiation, providing accurate readings across a broad spectrum of radiation energies. The ring’s versatility makes it suitable for various professional applications, from medical settings to nuclear power plants, to ensure precise and reliable data and maintain safety and regulatory compliance.

We built the TLD ring dosimeter to withstand harsh conditions, making it highly durable and resistant to environmental factors such as moisture. Its robust construction ensures that it continues to provide accurate and reliable dose measurements, even in the most demanding environments. This durability makes it a dependable choice for professionals who need consistent performance in their radiation monitoring equipment.

A TLD ring dosimeter is most effective in environments where precise extremity monitoring is necessary, such as medical facilities, nuclear power plants, and research laboratories. Our ring badge provides accurate dose measurements for hands, fingers, and wrists, making it invaluable for professionals who work with radioactive materials. Its ability to deliver reliable data in these settings helps enhance safety protocols and ensure regulatory compliance.

Once you return your TLD ring dosimeters to RDC, they’ll undergo a precise process to ensure accurate dose readings. We heat each dosimeter in a specialized reader to release stored energy as light. This light, proportional to the radiation dose, is measured by sensitive photomultiplier tubes and converted into an electrical signal to quantify the exposure.

Then, we analyze and compile the data into detailed reports, mail a copy to you, and post them in your online account within 10 business days, providing a reliable way to monitor and manage radiation exposure in your workplace.
