Convex 2c Exercise December 2015
A. Cortés Nuclear Safety and Safeguards National Commission
México
Eighth Meeting of the Representatives of Competent
Authorities
identified under the Early Notification Convention and the
Assistance Convention Vienna, June, 6-10, 2016
-
A 1,350 Ci Cs-137 Radiothepy unit was stolen
Cesio-137
-
• Federal Police finds the shielding
• No source inside
-
• A person in the Mexico City Airport (approximately 52.36 km
from the place where the vehicle and the shielding were found)
presents to the medical service with showing severe
gastrointestinal symptoms, he claims to have eaten at the “Wings”
restaurant in the international departures area while waiting for
his flight to depart.
• The airport security is informed of an abandoned backpack in
the “Wings” restaurant.
• The bomb squad arrives and evacuates a considerable area of
the airport around the “Wings” restaurant and proceeds to check the
backpack for explosives, but on the X-ray image a cylindrical
figure appears. The bomb technician proceeds to open the backpack
and sees that the cylinder has the radiation symbol stamped on it.
The bomb squad leader proceeds to notify this to his superiors and
the CNSNS is called for assistance.
• The CNSNS arrives at the airport and while moving towards the
restaurant they see increasing radiation levels, and some hot spots
are identified in the public area of Hall F, T1 ranging between 15
to 120 µSv/h dose. The CNSNS takes samples on these hot spots and
identifies Cs-137 contamination.
-
• CNSNS informs the IAEA that the source has been located within
the public area of Hall F at the Mexico City international airport
and it appears to be leaking. The source has been removed from the
device and placed in a Backpack. Initial surveys indicate that the
source has been damaged with contamination identified throughout
the public area
• Airport Security determines that the airlines will contact the
flights that departed within the last 2 hours and ask those that
are capable to return to the AICM for monitoring the passengers.
Those that departed more than 2 hours ago will proceed to their
destinations and SRE and the airlines will inform the countries of
the event and ask for their support in monitoring and, if needed,
decontaminate the passengers

Once the information goes to the media, persons start arriving
to AICM wanting to be monitored, so they are taken to a nearby
concert facility (500 persons)

Challenges: • Designing of the scenario: AICM, Civil Protection
Authority, Aeronautical Authority • Dose assessments calculation
for consistency • Time duration of the exercise: 24 hours (3
shifts/8 hours, at least 3 persons) • Language
Evaluation: • A lot of lessons identified from the mexican side
• A final (virtual) meeting with the IAEA was needed to evaluate
the exercise
