Corrigendum

Corrigendum to ICRP Publication 139: Occupational radiological protection in interventional procedures. [Ann. ICRP 47(2), 2018]. DOI: 10.1177/0146645317750356.

An error has been identified in the following equation in Annex B, Paragraph B9, p. 116:

$$E=\sum _T{w}_{\text{T}}{H}_{\text{T}}=\sum _T{w}_{\text{T}}\sum _T{w}_{\text{T}}{D}_{\text{T},\text{R}}$$

In this equation, the second summation should be over R rather than T

$$E=\sum _T{w}_{\text{T}}{H}_{\text{T}}=\sum _T{w}_{\text{T}}\sum _R{w}_{\text{R}}{D}_{\text{T},\text{R}}$$

ICRP apologises for any inconvenience or confusion caused by this error.
