Dose conversion factors for external irradiation

[Jean-Michel Mure <Jean-Michel.Mure@andra.fr>]

Hello Radsafers,

Could someone among the dosimetry specialists indicate me a reference
document where I could find readily useable dose conversion factors for
external irradiation (gamma, beta) from :
- a contaminated surface
- immersion in air
- immersion in water

I have got a list of conversion factors for 240 radionuclides from Kocher
(1980) but is not exhaustive and it might have been revised since then. Is
there an ICRP publication related to that topic like there is one for
ingestion and inhalation dose conversion factors (ICRP68) ?

Thanks in advance.
