Abstract

The ICRP Publication 66 Human Respiratory Tract Model (HRTM) has been applied to calculate general-purpose dose coefficients using default values of parameters relating to the material and the subjects. The ICRP Task Group on Internal Dosimetry is developing a 'Technical Document' giving guidance on application of the HRTM in situations where using specific information can improve dose assessment. It will include an analysis of the sensitivity of doses and bioassay quantities, lung retention and excretion rates, to relevant parameter values. Guidance will be given on characterising and sampling radioactive aerosols and on determining absorption rates. Examples will be given illustrating application of the HRTM in a wide range of situations. This paper provides a selective summary of the document at its current stage of development, with emphasis on determining absorption rates.
