The Radiation Monitoring by Mail program offers numerous clinical measurement services using thermoluminescent dosimeters (TLD's). Services include radiotherapy patient monitoring of external beam treatment and intracavitary accelerated partial breast irradiation (APBI). Measurements are made on patient or on phantom with well characterized calibrated TLD's mailed from the RCL. In addition, custom exposure measurements using TLDs are available. The RCL also provides a radiochromic film service that is used to measure the 3-dimensional radiation field center / mechanical center coincidence and provide information on radiation contours and dose profiles for the Gamma Knife radiosurgy and other similar devices.
