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
X-Ray
baggage scanner, 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 X-ray
baggage security scanner 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 x-ray
bag scan. 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.
After learning the information above, do you have a full understanding of baggage
x ray scanner radiation? For more information about security scanners, you
