European foreword
This document (EN 14175-8:2022) has been prepared by Technical Committee CEN/TC 332 “Laboratory
equipment”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2023, and conflicting national standards shall
be withdrawn at the latest by January 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United

Introduction
Before using radioactive materials, a safety (risk) assessment is performed with reference to legislation
and advice from radiation protection experts.
The maximum amount of activity allowed for every activity with radioactive material is evaluated in
accordance to the three principles of radiological protection, namely justification, optimization, and the
application of dose limits, clarifying how they apply to radiation sources delivering exposure and to
individuals receiving exposure. Shielding or abatement system when appropriate are also evaluated.
There are three kinds of dose in radiological protection. Absorbed dose is a measurable, physical
quantity, while equivalent dose and effective dose are specifically for radiological protection purposes.
Dose is used in this document as defined in IAEA Glossary 2018.
Attention is drawn to the publication IAEA SAFETY STANDARDS SERIES, Radiation Protection and Safety
of Radiation Sources: International Basic Safety Standards General Safety Requirements Part 3 (No. GSR
Part 3).
1 Scope
This document specifies the characteristics of fume cupboards, as defined in EN 14175-1, for work with
unsealed radioactive materials with specific requirements regarding radiation protection. It does not
apply to fume cupboards, glove boxes or hot cells (shielded radiation containment cells which can
incorporate fume extraction).
The purpose of this document is to set out rules for the design and testing of fume cupboards for work
with unsealed radioactive materials, in order to provide guidelines for the manufacturer, planner,
installer, operator, assessor and the authorities.
This document only covers bench type fume cupboards.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 14175-1, EN 14175-2:2003,
EN 14175-3:2019, EN 14175-4, EN 14175-6 and the following apply.

• ISO Online browsing platform: available at https://www.iso.org/obp
3.1
abatement system
equipment dedicated to the removal or reduction of pollutants from releases from installation to air or
liquid
Note 1 to entry: Examples for abatement systems are filters, scrubbers or holding tanks.
3.2
activity
quantity A of radionuclide that disintegrates in a second, defined as:
At = ddN / t
( )
where
dN is the expectation value of the number of spontaneous nuclear transformations from the
given energy state in the time interval dt.
−1
Note 1 to entry: The SI unit for activity is reciprocal second (s ), termed becquerel (Bq).
Note 2 to entry: This definition is generally based on the definition of activity given in Council Directive
2013/59/Euratom.
3.3
chamber
materials that form the work space
3.4
contamination
unintended or undesirable presence of radioactive substances on surfaces or within solids, liquids or
gases or on the human body
Note 1 to entry: The term ‘contamination’ might have a connotation that is not intended. The term ‘contamination’
refers only to the presence of radioactivity, and gives no indication of the magnitude of the hazard involved.
[SOURCE: Council Directive 2013/59/Euratom, Chapter II, Article 4 (18) – modified, Note 1 to entry was
added]
3.5
decontamination
complete or partial removal of contamination by a deliberate physical, chemical or biological process
Note 1 to entry: This definition is intended to include a wide range of processes for removing contamination from
people, equipment and buildings, but to exclude the removal of radionuclides from within the human body or the
removal of radionuclides by natural weathering or migration processes, which are not considered to be
decontamination.
