Here are a few key points that should answer your questions.
Facts on signage for GEH-C
· Section 21 of the CNSC’s Radiation Protection Regulations,
“Posting of Signs at Boundaries and Points of Access,” prescribes when
and where signage is required by licensees.
on the amount(s) of nuclear substance(s) present or the potential for
radiation exposure, licensees are required to post signs with the
radiation warning sign (trefoil) and the words “Rayonnement – Danger –
Radiation” at the boundary of every point of access to an area, room,
enclosure or vehicle.
· No radiation warning sign is
required at the site boundary of GEH-C’s Toronto facility since the
conditions requiring the posting of radiation warning signs pursuant to
section 21 of the Radiation Protection Regulations are not present.
· Essentially, no external signage is required because there is
no radiation risk to the public outside of the building.
However, the CNSC encourages its licensees to proactively
communicate with communities and interested persons. There is nothing
preventing GEH-C from posting signage regarding its nuclear activities
at the Toronto facility.
Facts on GEH-C being designated a medium risk facility
· The CNSC considers the overall risk from GEH-C’s Toronto
facility to be low since the facility only uses natural uranium, which
means there is no possibility of a nuclear-related accident.
GEH-C has been assessed to be at the lower end of medium risk
facilities based on the facility handling a large quantity of uranium
· Potential hazards for all activities at
the facility have been identified and addressed in their safety
analysis report. GEH-C is required to put extra safety controls to
address the risk from the handling uranium powder and hydrogen gas.
· The CNSC has confirmed that these programs are working as
designed and the risks to workers and the public are well managed.
