Brisbane International Airport in Australia has rolled out new body scanning systems, which will randomly scan passengers to improve security.
Deployed as part of the Australian Government's move to introduce body scanning technology at eight international gateway airports, the new body scanners will function along with the airport's existing walk-through metal detectors.
Installation of scanners is part of a plan signed into Federal law passed on 15 August 2012, following their trial at Sydney and Melbourne airports.
The scanners use millimetre-wave non-ionising radio frequency energy and emit around 10,000 times reduced radio frequency energy when compared to an average mobile phone call.
Passenger privacy is protected through using a generic human outline for all passengers, which is deleted following the completion of scanning.
However, passengers could also opt for alternate scanning option by undergoing three security checks that include a metal detector scan, body frisk and explosives test.
According to the Australian Government, airport staff, pilots and cabin crew may also have to undergo a body scan on a random basis, while those passengers who refuse to go through scanning will not be allowed to board the flight.
Body scanners are also deployed for aviation security screening in several nations, including the US, Canada, the UK, Thailand and the Netherlands.
Brisbane Airport (BAC) is planning to build a new A$1bn parallel runway, which is anticipated to be operational by 2018.
The new 3,600m-long runway will run parallel to the existing 01/19 runway and feature a 150m-wide centrally located runway strip.
