[ RadSafe ] Operational quantities

[John R Johnson]

Dear Mora Cañadas Juan Carlos

Some operational quantities for intakes are the annual limit on intake
(ALI), derived air concentration (DAC) and maximum permissible
intake/concentration (MPC/I).

Details for available publications that describe these can be found on the
ICRP http://www.icrp.org/ or NCRP http://www.ncrponline.org/ web sites.

Subject: [ RadSafe ] Operational quantities



Good morning.

I would like to ask a conceptual question to the group.

I have an undertanding problem on this "operational quantity" concept. I
have always use this concept for external doses (Hp(10), H*(0.07)...), but I
have read some references about operational quantities for intake of
radionuclides.

Can anyone explain to me what those internal operational quantities are? Or
at least any document where I could read about it?

Thank you very much.
