Corrigendum

Corrigendum to ICRP Publication 130: Occupational intakes of radionuclides: Part 1 [Ann. ICRP 44(2) 2015]. DOI 10.1177/0146645315577539.

An addition sign which should have been placed immediately after the closing square bracket was accidentally omitted in Eq. 3.3. The corrected equation is shown here:

$\frac{d{A}_{i,j}(t)}{\mathrm{dt}}=\sum _{\genfrac{}{}{0ex}{}{k=1}{k\ne j}}^M{A}_{i,k}{\lambda }_{i,k,j}-A_{i,j}[\sum _{\genfrac{}{}{0ex}{}{k=1}{k\ne j}}^M{\lambda }_{i,j,k}+{\lambda }_i^P]+\sum _{k=1}^{i-1}{A}_{k,j}{\beta }_{k,i}{\lambda }_i^P$

(3.3)

where:

M   is the number of compartments describing the kinetics;

λ _{i, j , k}  is the fractional transfer rate of chain member i from compartment j (donor compartment) to compartment k (receiving compartment) in the biokinetic model;

${\lambda }_i^P$    is the physical decay constant of chain member i; and

β _{k, i}   is the fraction of the decays of chain member k forming member i.

In addition, in Eq. 3.5 the à in the numerator should have the suffix ‘i', the ‘j' for the summation should have been italic, and ‘A_1,j(0)' in the denominator should not have lined up with the ‘j' of the summation. Please see the corrected equation below:

${\tilde{a}}_{\text{i}}(r_{\text{S}},\tau )=\frac{{\tilde{A}}_i(r_{\text{S}},\tau )}{\sum _j{A}_{1,\text{j}}(0)}$
