Electromagnetic waves are the waves emitting from the Sun that doesn’t require any particular medium. There are many types of electromagnetic waves. Each type has its own frequency and wavelength range. This is the basis for the classification of the waves. Waves get specific properties due to their specific wavelengths and frequencies. Thus, waves are identified by their properties. UV rays are one of the electromagnetic waves. Most of the UV rays are harmful to human health. Thus, techniques are being adopted to decrease their direct exposure on Earth. UVC is a beneficial one of the UV rays. It has germicidal properties that mean it can kill virus, bacteria, and pathogens. Due to this property, it is being used in Uv lamp [หลอด UV, which is the term in Thai] since 1930.

Not all UV rays are harmful to human health:

There are different types of UV rays. It is a common thought that UV rays are harmful to human health but that is not the actual case. UV rays are also beneficial in many ways. There are three types of UV rays:

  • UV-A is used in medicines to treat different diseases. Little exposure to these rays does not cause any harm. However, prolonged exposure can cause some diseases.
  • UV-B is the most harmful of all the UV rays. It is the type of UV rays that actually cause serious health problems. Prolonged exposure can cause skin cancer.
  • UV-C has germicidal properties. Thus, it is being used in lamps for various purposes.

How UVC can reduce the spread of diseases?

UVC can destroy the structure of viruses and bacteria that spread diseases. Resultantly, the transmission of diseases is greatly reduced. UVC rays use the process of UVGI for killing the microorganisms. In this process, the structure of the microorganisms is destroyed by UVC rays. For this purpose, UVC lamps are being used in hospitals. In hospitals, there is a higher chance of spreading of diseases and UVC lamps play a great role to stop the spread of diseases.
