Internal Dosimetry Software

Introduction

Internal dosimetry software
Internal dosimetry related calculations are complicated Biokinetic models Dosimetric models Direct measurement system calibrations Several software packages have been developed to assist the dosimetrist The interpretation of internal dosimetry data can be a complicated process. Since the determination of intake and committed effective dose depends on the use of biokinetic and dosimetric models, interpretation of dosimetry measurements lends itself to the use of computer processing to expedite the interpretation process. Use of such software also contributes to harmonization of evaluation nationally and internationally.

Software is available for various tasks
Lookup tables Dose coefficients Retention fractions, etc. Dosimetry calculations Intake Committed equivalent dose Committed effective dose This unit is intended to give a brief overview of software that can be used for to access the data needed for internal dosimetry calculations - dose coefficients and retention fractions, and conduct dosimetry calculations for determination of intake, committed effective dose and committed equivalent dose. The software used for these applications ranges from simple look-up aids to programmes that embodies the biokinetic and dosimetric models developed by the ICRP. Software is also under development that would allow the use of Monte Carlo techniques for computational calibration of direct measurement systems. The unit will not, however, address software that is used for analysis of photon spectra for direct measurement applications.

Integrated Modules for Bioassay Analysis IMBA
Development began in 1997 by the NRPB Features modular structure, interacting via ASCII data sets Implements latest ICRP biokinetic models Fitting uses maximum likelihood method Use data recorded a being less than some minimum detection level Specify multiple intake regimes In 1994 to 1997, ICRP produced an abundance of new biokinetic models which were more realistic and scientifically justifiable than their predecessors. Impending legislation in the UK, which would encourage Approved Internal Dosimetry Services (ADSs) to implement these new models by Jan 2000, combined with a desire to have a unified approach to the interpretation of bioassay measurements prompted the UK ADS's to look for a way forward. The problem was exacerbated by the complex nature of the new models, and also the scarcity of software available to implement the models. It was out this challenge, that the concept of IMBA (Integrated Modules for Bioassay Analysis) originated in 1997. IMBA is now under development by the NRPB and the U.S. D.O.E. The central feature of the IM13A methodology is its modular structure. IMBA consists of six separate modules: each is an independent executable program which performs a specific task. The modules interact with each other via ASCII data sets. They implement the latest ICRP biokinetic models, and the parameter values required by the models are stored outside of the modules, in data sets. By running the modules in a specific order, it is possible to estimate intakes and calculate doses using the new ICRP biokinetic models. Parameter values used by the modules (e.g. AMAD, Absorption Rates etc) can be changed by editing the appropriate data files.
