Integrated Modules for Bioassay Analysis
RAMP's IMBA code (formerly IMBA Pro) is a suite of software modules for internal dosimetry that implements respiratory tract, GI-tract, tissue dosimetry, biokinetic and bioassay models as recommended by the International Commission on Radiological Protection (ICRP). Originally designed by the UK's Health Security Agency, the IMBA modules can estimate single or multiple intakes of different radionuclides and calculate resulting doses in the body and/or excrement for workers based on ICRP Publication 68 and US 10 CFR 835. IMBA provides a platform for conducting customized dose calculations with different user set parameters. The suite has functionalities to:
- Perform simple and more complex dose calculations
- Vapor inhalation modelling
- Forward bioassay calculations
- Intake estimation for multiple regimes
- Calculate bioassay quantities at different times from a specified intake
- Calculate equivalent organ doses and effective dose from a single intake
- Utilize a comprehensive list of 740 radionuclides (75 previously implemented in the IMBA Base Unit, and 665 more previously implemented within Additional Radionuclide Packs 1 and 2)
RAMP’s version of IMBA features the following add-ons:
- Multiple Intake Regimes
- Errors on Intake
- Multiple Bioassay Types
- Bayes Implementation
- Associated Radionuclides
- Tritium Tool
- Uranium Mixtures
- Compensation Type Calculations
- Uptake from Wounds
- Ingrowth of Americium
- Statistics Package
- Candu Models
RAMP does not distribute IMBA Lite or IMBA Plus. RAMP only distributes IMBA (formerly IMBA Pro) with all add-on functionalities built in. IMBA Pro, IMBA Plus, and IMBA Lite are successors to IMBA Professional Plus and IMBA Expert. RAMP's current distributable version of IMBA is considerably faster and more versatile than earlier predecessors. Additional details on IMBA may be found on the United Kingdom Health Security Agency website.
