Airport Security Screens Passengers Using New Technology

Checking baggage for explosives hasn't been a problem. Airport

security can put bags in x-ray machines, open them up to look

inside, or use advanced machinery that that check traces of

chemicals often used in explosives.

But checking people's bodies isn't so easy. A TSA initiative

that began last September to rigorously frisk more people led to

dozens of sexual harassment complaints. So the TSA turned to

technology installing what looks like a longer, more complex

walk-through metal detectors in nine airports around the country.

Jose Ralls is the TSA director from McCarran International in Las Vegas.

Jose Ralls: The machine actually will talk to the individual,

telling them to stand inside and wait, and as soon as they are

cleared, it will tell them to proceed.

From a distance, Mr. Ralls watches one airport passenger go through the process.

Jose Ralls: Now he knows to go on through, and he just waits, and as soon as the air is analyzed he will be allowed to proceed

forward.

The machine blasts air downward and across whoever inside the

portal. Mr. Ralls says that often startles people.

Jose Ralls: That's why our focus out there is to explain to

them what will be taking place,the noise that they will be hearing.

The way it's supposed to work is that suspicious particles on

clothing and exposed skin are blasted towards the floor -- where,

within seven seconds, the machine can detect 40 types of

explosives. If any are found, security is alerted.

According to the manufacturer, Smith Detection, the portals also have less than 1% error rate. Company vice president Mark

Lastra says this technology is commonly used elsewhere.

Smith Detection: Mostly highly controlled facilities,

sensitive security, such as nuclear power plants and government

buildings with high security needs.

Along with increasing security, the TSA hopes to cut down on passenger wait times. It is collecting data from the airports in

this test base to see if the machines are faster and more

efficient than human inspectors.

The Transportation Security Administration plans to deploy

five more of these portals elsewhere in the nation by late spring.

Eventually it would like the explosive detectors to be as common

as metal detectors.
