Radiation Monitoring by Mail Services

Radiation Monitoring by Mail Services


The University of Wisconsin Radiation Monitoring by Mail (UWRMM) provides radiation monitoring and QA services by sending Thermoluminescent Dosimeters (TLDs) to the customer through the mail. These devices are exposed by the customer and returned to the UWMRRC for reading and analysis. Reports are generated and sent to the customer. It is our goal to provide the most prompt and accurate service possible.

The Therapy Dose Verification service uses TLDs that are well characterized and batched into sets.  They may be used on patient or on phantom.

Therapy Dose Verification TLD Service

TLDs are used to monitor the dose to areas receiving direct radiation as well as areas that should be shielded from the primary beam. Sets of dose-response Calibration TLDs are included with each set (no charge) which are exposed by the customer to known radiation doses from a single beam energy. These doses bracket the doses expected during the therapy exposures. The dose-response TLD data is used to establish the dose-response to TLD reading through linear regression analysis.  Reports are usually completed and emailed to the customer the same day that they are received by the UW TLD Lab. We recommend using more than one chip at each patient site for best statistics.

TLD-based Linear Accelerator Output Verification

This service provides an independent, third party verification of linear accelerator output for photon and electron energies under AAPM TG-51 conditions using calibrated TLDs packaged in Virtual Water™ waterproof ion chamber surrogates, For more information, go to the Linac Output Verification page.
