This is an issue for PRA quality because omission of skin absorption could underestimate doses in such cases. Qualification The analysis shall include applicable exposure pathways including cloudshine, groundshine, skin deposition, skin absorption, inhalation and ingestion, and the effect of mitigation actions on received dose.
