Committee on Medical Internal Radiation Dose (MIRD)
Radiation dosimetry provides the fundamental quantities used for radiation protection, risk assessment, and treatment planning. The MIRD Committee develops standard methods, models, assumptions, and mathematical schema for assessing internal radiation doses from administered radiopharmaceuticals. The MIRD approach simplifies the problem of assessing dose for many different radionuclides—each with its unique radiological characteristics and chemical properties as labeled compounds—in the highly diverse biological environment represented by the human body, internal organs, tissues, and fluid compartments. The virtue of the MIRD approach is that it systematically reduces complex dosimetric analyses to methods that are relatively simple to use, including software tools for experimental and clinical use.
- Develop and provide a standardized framework and methodology for calculation of internal dose quantities in nuclear medicine.
- Compile, evaluate and disseminate data needed to implement standardized internal dosimetry methods including radionuclide decay properties and emissions, energy absorbed fractions and anatomic models.
- Collect and assess experimental and peer-reviewed data to publish dose estimate reports for selected new radiopharmaceuticals which significantly impact the current practice of nuclear medicine.
- Provide peer-reviewed evaluations of proposed new dosimetry models and methods including correlating dose with biological response for cellular, animal and clinical trials data.
- Address other critical and timely dosimetry issues that may impact the current practice of nuclear medicine.
- Develop, test and publish software and internet tools that implement MIRD calculation models and techniques including dose-response data and biological effective or equivalent dose quantities.
- Actively work with other national and international committees through joint meetings and symposia to establish uniformity in dosimetry models, techniques, named special quantities and units of dose and biological response.
