‘‘Exercise 3’Exercise 3’

Purpose:Compare unweighted internal and external absorbed dose rates assuming 1 Bq kg-1 in organism & 1 Bq unit-1 media respectivelyRadionuclides (n=74) considered – those from draft ICRP RAP report (+55Fe)

Did not include noble gases (Ar, Kr Rn) which had been requested by some group members

For comparison all predictions normalised to ‘infinite dose rate’ for given RN-exposure scenario

Infinite dose rate estimated assuming inclusion of progeny with T1/2’s ≤ 20 d

Infinite dose rate is same for all geometries for given RN-exposure scenario
