UWAccredited Dosimetry Calibration Laboratory (UWADCL)
The American Association of Physicists in Medicine (AAPM) accredits the ADCL for the calibration of diagnostic and therapy radiation measurement instrumentation and radioactive sources. The ADCL provides the highest quality and most comprehensive calibration service in the industry.
UW Radiation Calibration Lab (UWRCL)
The UWRCL specializes in providing services not available under the AAPM UWADCL scope. UWRCL services are accredited by A2LA, in compliance with ISO/IEC 17025:2017.
Radiation Monitoring by Mail (RMM)
The RMM service offers provides beam measurement using Thermoluminescent Dosimeters (TLDs) for therapy patient monitoring. Measurements can be made on patient or on phantom, with calibrated TLDs mailed from the RCL. In addition, mammographic, general diagnostic, and CT exposure measurements using TLDs. The RCL also provides a Radiochromic Film service that is used to measure the 3-dimensional radiation field center / mechanical center coincidence as well as provide information on radiation contours and dose profiles for the Gamma Knife and other similar devices. RMM services are accredited by A2LA, in compliance with ISO/IEC 17025.
UWADCL Scope of Accreditation
The American Association of Physicists in Medicine (AAPM) accredits the UWADCL for the calibration of diagnostic and therapy radiation measurement instrumentation and radioactive sources. The UWADCL provides the highest quality and most comprehensive calibration service in the industry. The UWADCL is also accredited by the American Association for Laboratory Accreditation (A2LA) to the international standard ISO/IEC 17025:2017.
