Endorsement notice
The text of the International Standard IEC 61005:2014 was approved by CENELEC as a European
Standard with agreed common modifications.
COMMON MODIFICATIONS

Replace “minimal” with “minimum” (in the term an in the note).

6 Radiation detection requirements
6.4 Variation of the response due to neutron energy
6.4.2 Requirements

Replace the fourth paragraph starting with “The test distance should be at least 3 times …”
with “The test distance should be at least 3 times the sum of the largest linear dimension of
the source and the detector. In case of neutron fields according to ISO 8529, the scatter
contribution to the indicated value shall be determined in compliance with ISO 8529-2 and the
indicated value shall be corrected for scattered neutrons.”
In the note, replace “realistic work place” with “workplace”.

6.6 Variation of the response due to angle of incidence
6.6.3 Test method
Replace the fourth and fifth sentence starting with “The scatter contribution to the indicated
value …” with “In case of neutron fields according to ISO 8529, the scatter contribution to the
indicated value shall be determined in compliance with ISO 8529-2 and the indicated value
shall be corrected for scattered neutrons.”

6.13 Response to other external ionizing radiations
Replace the paragraph by “If the detector’s cover does not shield alpha and beta radiation,
the response due to alpha and beta radiation should be measured – and the results should be
documented.”
7 Additivity of indicated value
7.2 Test method
H +−HH
iK iL
iK+L
( )
Replace the equation with ∆=H
imix
