Annual limit on intake
Revision as of 18:36, 12 August 2021 by Chris Clement (talk | contribs)
(See also Derived air concentration) ALI was defined in ICRP Publication 60 as an intake (in Bq) of a radionuclide in 1 y that would lead to a committed effective dose of 20 mSv. The average ALI for workers is thus:
[math] ALI_j = \frac{0.02}{e_i(50)} [/math]
The Commission does not recommend the use of ALI because it considers that for compliance with dose limits it is the total dose from external radiation as well as from intakes of radionuclides that must be taken into account.

Historically
The activity intake (Bq) of a radionuclide that would result in a committed effective dose corresponding to the annual dose limit, considering exposure of a worker to only this radionuclide
