Raleigh-Durham International Airport is using beefed-up security measures to comply with regulations that went into effect Jan. 1 requiring airports to screen all checked luggage for explosives.
The U.S. Transportation Security Administration installed the new security devices at RDU on Dec. 29, said RDU Communications Manager Mindy Hamlin.
Hamlin said RDU is using an explosive detection system called CTX, which uses CT scan X-rays to comply with the new rules.
In addition to scanning all checked luggage, airport security personnel at RDU also are wiping down carry-on luggage to collect traces of possibly explosive chemicals.
"When you're working with explosives, there is a micropowder that gets on everything. It is really difficult to get it off," said TSA spokeswoman Heather Rosenker.
A fabric that is used to wipe down the luggage picks up any trace of micropowder, she said. When the fabric is fed into an electronic analyzer, it will register any traces found.
The explosive trace detection is used at security checkpoints outside the concourses along with standard random security searches or when the luggage appears suspicious.
Hamlin said there were no delays during the busy holiday season because of the new security checks.
The CTX system screens checked baggage, which primarily is processed behind the scenes and does not cause delays for passengers, Hamlin said.
