BS ISO 16659-1:2022 Ventilation systems for nuclear facilities. In-situ efficiency test methods for iodine traps with solid sorbent - General requirements
1 Scope
The scope of ISO 16659 series is to provide different test methods aiming at assessing the efficiency of radioactive iodine traps in ventilation systems of nuclear facilities. The ISO 16659 series deals with iodine traps containing a solid sorbent — mainly activated and impregnated charcoal , the most common solid iodine sorbents used in the ventilation systems of nuclear facilities — as well as other sorbents
for special conditions (e.g. high temperature zeolites ).
The scope of this document is to provide general and common requirements for the different
test methods for industrial nuclear facilities. The different methods will be described
in other specific parts of ISO 16659 series. Nuclear medicine applications are excluded from the scope of ISO 16659 series.
In principle, ISO 16659 series is used mainly for filtering radioactive iodine, but other radioactive gases can
also be trapped together with iodine. In such a case, some specificity may have to
be adapted for these other radioactive gases in specific parts of ISO 16659 series.
This document describes the main general requirements in order to check in situ the
efficiency of the iodine traps , according to test conditions that are proposed to be as reproducible as possible.
