Airport security is an important part of ensuring the safety and security of passengers. To detect potential threats, airports use a variety of machines and methods such as metal detectors, X-ray machines, ion mobility spectrometry, and even trained dogs and honeybees. This article will explore these different machines and methods in more detail to give readers a better understanding of how airport security works.
Metal detectors are one of the most common tools used to detect weapons or other metallic objects at airports. These devices work by sending electromagnetic waves through the body which then interact with any metal objects that may be present. The detector then emits an alarm if it detects something suspicious. Metal detectors can also be used to detect gold and other non-metallic materials.
Which Are Used In Airport Security To Identify Hidden Objects?
X-ray machines are another tool commonly used for airport security screenings. They emit a beam of low-energy radiation which is able to penetrate clothing and luggage to create images of what’s inside. X-ray machines are very effective at detecting weapons and drugs that may be hidden in bags or on the person.
Ion Mobility Spectrometry:
Ion mobility spectrometry (IMS) is a type of technology that uses ionizing radiation to scan passengers and their belongings. IMS works by creating ions from molecules in the air around the passenger, which then move through a drift tube under the influence of an electric field. Different substances have different mobility rates which allow them to be identified and detected. IMS is especially useful for detecting explosives and illegal drugs.
Training Dogs & Honeybees:
In addition to using machines, some airports are now training dogs and honeybees to help with security screenings. Dogs are trained to detect certain smells associated with explosives and illegal drugs. Honeybees, on the other hand, are being trained to detect the same chemicals but with a much higher accuracy rate. Both of these methods provide airports with an additional layer of security.
Security Guards And Military Forces (RCMP):
All Canadian airports are secured by the local police forces – Royal Canadian Mounted Police. At all entry points, there are highly trained and well-equipped police forces and military forces deployed to check the air tickets of all passengers.
In conclusion, airports use a range of machines and methods to ensure the safety and security of passengers. Metal detectors, X-ray machines, Ion Mobility Spectrometry, and even trained dogs and honeybees are all used to detect potential threats. Security guards and military forces are also stationed at airports to provide additional protection.
