Misunderstanding of Hand Held Laser Scanner Radiation
Most people share the similar experience that you have to receive a full body check by airport security personnel when you are going on a flight. Many people may have the worry that the radiation such scanners released is harmful to our health. Here I want to clarify the hand held laser scanner radiation specially. You’d better listen with respectful attention.
First of all, you’d better know the definition of laser. Laser stands for Light Amplification by the Stimulated Emission of Radiation. One basic type of laser consists of a sealed tube, containing a pair of mirrors, and a laser medium that is excited by some form of energy to produce narcotics detecting, or invisible ultraviolet or infrared radiation. There are many different types of lasers and each uses a different type of laser medium. Common laser media include gases such as argon or a helium and neon mixture, solid crystals such as ruby, and liquid dyes or chemicals. When energy is applied to the laser medium, it becomes excited and releases energy as particles of light (photons). The metal detector gate uses the technology of laser. Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the eye, such as ultraviolet or infrared radiation. In general, laser radiation is not in itself harmful, and behaves much like ordinary light in its interaction with the body. Laser radiation should not be confused with radio waves, microwaves, or the ionizing x-rays or radiation from radioactive substances such as radium. Therefore, don’t worry about the hand held laser scanner radiation.
Metal detector scanners, such as liquid Inspection equipment use a low-frequency electromagnetic field to look for metal objects. Anything that generates or uses electricity, such as power lines and household appliances, produces electromagnetic fields. At the low levels of a Portable metal detector, this exposure is considered safe for everyone, including pregnant women. The same holds true for the wands that are sometimes passed over individual passengers.
Some airports use another type of scanner. This is called a backscatter narcotics detecting equipment. It gets its name from the type of technology that is used to create an image. The system sees through clothing, but not skin, to spot concealed items. It’s similar to the X-ray scanners used on your luggage at the airport. Although it's called an X-ray system, it is safe for you to pass through one. Even 200 backscatter screenings wouldn’t expose you to enough radiation to affect you. This is similar to the amount you would be exposed to on a three-hour flight.
