 New ISO Standard - Supplementary Ionizing-Radiation
Warning Symbol
Latest News
Friday, 09 February 2007

A new radiation warning symbol, to supplement the
existing trefoil symbol has been published by ISO as
Standard #21482- Ionizing-Radiation Warning
–Supplementary symbol. The trefoil symbol has no
inherent meaning and only those people that have been
educated in its meaning have knowledge that it
represents the presence of ionizing radiation. The new
symbol is the completion of a multi-year effort by the
IAEA to develop a universal radiation warning symbol
that anyone anywhere will understand the message of
“Danger- Stay Away”. The new symbol was developed with
human factor experts, graphic artists, and radiation
protection experts. Many possible symbols were
initially tested in international children, and then
those symbols that were most successful in conveying
the desired message were tested further by the Gallup
Institute in both people with limited education and
those educated in 11 countries around the world. The
new symbol universally conveyed the intended message
regardless of the person’s age, education or cultural
background.

The symbol is intended for IAEA Category 1, 2 and 3
sources defined as dangerous sources capable of
causing death or serious injury. The symbol should be
placed on the device housing the source, as a warning
not to dismantle the device or to get any closer.
Where practical, it should be placed under the device
cover such that it is not visible under normal use but
would be visible if anyone attempts to disassemble the
device. The symbol is not intended for doors or
shipping containers.

In the near future, many source manufactures have
agreed to use the symbol on newly manufactured large
sources such as irradiators, teletherapy heads and
industrial radiography units. Strategies to place the
symbol on existing large sources are being developed
by the IAEA. The standard can be obtained at
www.iso.org.
