Does ultrasound have radiation?

The rapid development of modern science and technology has brought about earth-shaking changes in people's lives. Among them, the application of various advanced technologies has greatly facilitated people's lives. For example, ultrasound is a widely used technical principle. A large number of electrical appliances in life use ultrasound, which has brought great benefits to people's lives. However, ultrasound is a high-frequency sound wave. Let’s take a look at whether ultrasound has radiation.

Ultrasound is not harmful to humans, but beneficial.

In fact, sound waves are one of the categories of sound and are mechanical waves. Sound waves refer to a type of longitudinal wave that can be felt by the human ear and its frequency range is 16Hz-20KHz. When the frequency of a sound wave is lower than 16 Hz, it is called infrasound, and when the frequency is higher than 20 KHz, it is called ultrasonic sound wave.

Ultrasonic waves have the following characteristics:

1. Ultrasonic waves can be effectively transmitted in media such as gas, liquid, solid, and solid solution.

2. Ultrasound can transmit very strong energy.

3. Ultrasonic waves will produce reflection, interference, superposition and resonance phenomena.

4. When ultrasonic waves propagate in liquid media, they can produce strong impact and cavitation phenomena on the interface.

Ultrasound is a member of the sound wave family.

Sound waves are the propagation form of the mechanical vibration state (or energy) of an object. Vibration refers to the reciprocating motion of a material's particles near its equilibrium position. For example, when a drum is struck, it vibrates up and down, and this vibration state propagates in all directions through the air medium, which is the sound wave.

Ultrasonic waves refer to sound waves with a vibration frequency greater than 20KHz that cannot be heard or felt by humans in the natural environment.

The concept of ultrasound therapy:

Ultrasound therapy is an important part of ultrasound medicine. During ultrasound therapy, ultrasonic energy is applied to the diseased part of the human body to achieve the purpose of curing the disease and promoting the body's recovery.

Ultrasound is widely used in diagnostics, therapeutics, engineering, biology and other fields around the world. Safeline home ultrasound therapy machine belongs to the application category of ultrasound therapy.
