New Symbol for Radiation Dangers

newradiationsymbol_300x200With radiating waves, a skull and crossbones and a running person, a new ionizing radiation warning symbol is being introduced to supplement the traditional international symbol for radiation, the three cornered trefoil.

The new symbol is being launched today by the IAEA and the International Organization for Standardization (ISO) to help reduce needless deaths and serious injuries from accidental exposure to large radioactive sources. It will serve as a supplementary warning to the trefoil, which has no intuitive meaning and little recognition beyond those educated in its significance.

“I believe the international recognition of the specific expertise of both organizations will ensure that the new standard will be accepted and applied by governments and industry to improve the safety of nuclear applications, protection of people and the environment,” said Ms. Eliana Amaral, Director, Division of Radiation, Transport and Waste Safety, IAEA.

The new symbol is aimed at alerting anyone, anywhere to the potential dangers of being close to a large source of ionizing radiation, the result of a five-year project conducted in 11 countries around the world. The symbol was tested with different population groups – mixed ages, varying educational backgrounds, male and female – to ensure that its message of “danger – stay away” was crystal clear and understood by all.

“We can´t teach the world about radiation,” said Carolyn Mac Kenzie, an IAEA radiation specialist who helped develop the symbol, “but we can warn people about dangerous sources for the price of sticker.”

The new symbol, developed by human factor experts, graphic artists, and radiation protection experts, was tested by the Gallup Institute on a total of 1 650 individuals in Brazil, Mexico, Morocco, Kenya, Saudi Arabia, China, India, Thailand, Poland, Ukraine and the United States.

The symbol is intended for IAEA Category 1, 2 and 3 sources defined as dangerous sources capable of death or serious injury, including food irradiators, teletherapy machines for cancer treatment and industrial radiography units. The symbol is to be placed on the device housing the source, as a warning not to dismantle the device or to get any closer. It will not be visible under normal use, only if someone attempts to disassemble the device. The symbol will not be located on building access doors, transportation packages or containers.

“The new ionizing radiation warning symbol (ISO 21482) is the latest successful result of long-standing cooperation between the IAEA and ISO. We encourage the symbol´s rapid adoption by the international community,” said ISO Secretary-General Alan Bryden.

Many source manufacturers plan to use the symbol on new large sources. Strategies to apply the symbol on existing large sources are being developed by the IAEA.

  1. Too bad they did not look at the relatively well-known reaction of young people (at least in the English speaking world): when they see S&CB on a container of poison, they think “pirate food” and ingest it.

  2. “radiating waves, a skull and crossbones and a running person”

    Where are the weeping mother, Scrooge McDuck swimming in profits, and a gobsmacked Andrew Sullivan?

  3. As a professional graphic designer I can only say that this sign and symbols makes absolutely NO sense.

    Radiation will turn you into a dead running zombie!

    Please the old one works just fine.

    Wow… has rebranding gotten this out of control?
