- Ultraviolet (UV) light is a form of electromagnetic emission with shorter wavelengths than visible light but longer wavelengths than X-rays. UV radiation is indiscernible to the human eye but can cause skin damage and even cancer. UV light is produced by the sun and can also be generated by manufactured sources such as tanning beds and UV lamps.

UV lightworks by penetrating the skin and damaging the DNA inside cells. The damage to DNA can cause cancer. The sun is the primary source of UV light, but there are artificial sources of UV light, too. These include tanning beds, welding torches, and mercury vapor lamps. UV light can also be found in some germicidal lamps. These are used to clean ...
What is ultraviolet radiation? We only found out about it in 1801. Johann Wilhelm Ritter, a German physicist, discovered it while experimenting with silver chloride in a leather camera case. He found that the leather blackened where it was exposed to sunlight but not where exposed to the light from a candle. Ritter called this new kind of light (de...
When most people talk about ultraviolet radiation, they are not aware of the many different types of UV radiation and how they differ from one another. UV light is categorized based on wavelength. Plus, UV light types have different photon energies. Photon energyis a measurement of the ultraviolet light’s wavelength and frequency. Each type of UV r...
UV light has multiple applications today. For example, it helps produce Vitamin D in the human body. Vitamin D is an essential vitamin that helps the body absorb calcium. It also regulates the immune system and neuromuscular function. However, the human body only produces Vitamin D when it is out in the Sun. Therefore, the World Health Organization...
UV rays can be both good and bad for us. They help our bodies produce vitamin D and can cause skin cancer. Here are some hazards of UV light:
Although it can harm humans, UV light can be very beneficial. Here are some advantages of UV radiation.
Which Type of UV Radiation Is Most Harmful?
UV-C is the most harmful type of UV radiation. It is also the shortest wavelength and is entirely absorbed by the atmosphere, so we are not exposed to it.
How Does UV Light Affect Humans?
UV light can cause several health problems in humans, including skin cancer, eye damage, and immune system suppression.
What Are Some Ways to Reduce Exposure to UV Radiation?
You should avoid being in the sun during the peak UV hours, generally between 10 a.m. and 4 p.m. You should wear protective clothing, like pants and long-sleeved shirts. More importantly, use sunscreen when you go outside.
UV lightfalls in the 10–400 nm range, with UVC (100–280 nm) being the most harmful. The significant health effects are skin cancer, eye damage, and immune system suppression. The most significant health hazard posed by UV radiation is skin cancer. Ultraviolet light can damage our cells’ DNA, which can lead to cancer. The risk of skin cancer increas...
Mar 8, 2024 · 1. Sterilization. Image Credit: MBLifestyle, Shutterstock. The medical industry relies on UV light as one way to sterilize rooms and objects used in this field. It has a similar effect on the DNA of these disease-causing organisms, rendering them harmless. Low-pressure mercury vapor lights are one source.
