Exercise 3
Purpose Compare unweighted internal and external
absorbed dose rates assuming 1 Bq kg-1 in
organism 1 Bq unit-1 media respectively Radionuc
lides (n74) considered those from draft ICRP
RAP report (55Fe) Did not include noble gases
(Ar, Kr Rn) which had been requested by some
group members

Exercise 3

• Organism geometries taken from information
  supplied for ICRP RAPs to BWG Exercise 1 need to
  check consistent with in-press report

Hmmmm Flatfish egg 0.2 0.2 0.2

Multiple runs of same model

• RESRAD-BIOTA results input using available
  software tool where radionuclide included vs
  more complete set of results submitted by ANL
• ERICA (i) two sets non-developer use of Tool
  default non-developer create organism (ii)
  ICRP RAP report, (iii) K-Biota, (iv) results
  using default values
• RD128 (i) available spreadsheets (ii)

For comparison all predictions normalised to
infinite dose rate for given RN-exposure
scenario Infinite dose rate estimated assuming
inclusion of progeny with T1/2s 20 d Infinite
dose rate is same for all geometries for given
RN-exposure scenario
