Ultraviolet (UV) radiation is a type of electromagnetic radiation emitted by the sun. It's invisible to the human eye and has shorter wavelengths than visible light.UV rays can have both beneficial and harmful effects on life, affecting things like vitamin D production in humans but also causing sunburn, skin aging, and an increased risk of skin cancer with overexposure. What is an ULTRAVIOLET RADIATION?

Just like any other EM Wave, the speed of UV Waves are 3 x 10^8 m/s SPEED Advincula | The frequency of Ultraviolet waves ranges 7.5 x 10^14 to 3 x 10^16. Its frequency is higher than Visible Light but lower than X-Ray. Frequency

Applications of Ultraviolet Radiation

Applications of Ultraviolet Radiation

Gutierrez |

Disinfection: UV light is used to disinfect air, water, and surfaces, as it can kill or inactivate microorganisms, including bacteria and viruses.

Applications of Ultraviolet Radiation

Gutierrez |

Fluorescent Lamp: UV light is used in fluorescent lamps, where phosphor coatings absorb UV radiation and re-emit visible light

Applications of Ultraviolet Radiation

Gutierrez |

Forensics: UV light is utilized in forensic investigations to reveal bodily fluids and other evidence that may be invisible under normal light.

Applications of Ultraviolet Radiation

Tanning beds:

Some tanning beds use UV radiation to induce skin tanning, although excessive exposure can be harmful. Insect Traps: UV light is attractive to insects, and devices like bug zappers use UV lamps to lure and eliminate insects.

Applications of Ultraviolet Radiation

Polymer Curing: UV radiation is employed in industries for curing adhesives, inks, and coatings on various materials like plastics and metals.

Ultraviolet (UV) radiation is generally classified as non-ionizing radiation. Most UV radiation doesn't have sufficient energy to ionize atoms or molecules, unlike X-rays or gamma rays. However, the higher- energy end of the UV spectrum, specifically the "far ultraviolet" region, can have some ionizing properties Macasilhig |

Far ultraviolet (FUV) radiation refers to the region of the ultraviolet spectrum with wavelengths shorter than those in the "near" or "middle" ultraviolet range. Extreme UV radiation has the shortest wavelength range and highest energies of the regions of the ultraviolet spectrum, and lies on the border between UV and X-ray radiation.

Some examples & uses of Ultraviolet UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. UV are also used in medicinal treatment, some of killing bacteria and treating cancer. They are helpful in killing the tumour cells in the human body. Babor |
