Why are UV rays harmful wavelength?
The three types of UV radiation are classified according to their wavelength. They differ in their biological activity and the extent to which they can penetrate the skin. The shorter the wavelength, the more harmful the UV radiation. However, shorter wavelength UV radiation is less able to penetrate the skin.
Why does UV light cause cancer?
When your skin is unprotected from the sun, ultraviolet (UV) radiation can damage your DNA. If the body is unable to repair this damage the cell can begin to divide and grow in an uncontrolled way. This growth can eventually form a tumour.
Why does UV radiation increase the risk of cancer?
Damage from UV exposure is cumulative and increases your skin cancer risk over time. While your body can repair some of the DNA damage in skin cells, it can’t repair all of it. The unrepaired damage builds up over time and triggers mutations that cause skin cells to multiply rapidly. That can lead to malignant tumors.
Why are UV rays and x rays so dangerous?
They have more energy than visible light, but not as much as x-rays. These rays can cause skin cells to age and can cause some indirect damage to cells’ DNA. UVA rays are mainly linked to long-term skin damage such as wrinkles, but they are also thought to play a role in some skin cancers.
Why do nail salons use UV lights?
Lamps that emit ultraviolet (UV) radiation have become a standard at many nail salons, causing patrons to wonder about skin cancer risks while getting a manicure. These lamps are typically used to speed-dry regular manicures, and they are required to set gel manicures.
How are UVA and UVB rays related to skin cancer?
Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning. While UVA and UVB rays differ in how they affect the skin, they both do harm. Unprotected exposure to UVA and UVB damages the DNA in skin cells, producing genetic defects, or mutations, that can lead to skin cancer (as well as premature aging.)
How are gamma rays and X-rays linked to cancer?
What Causes Cancer? When talking about radiation and cancer risk, it is often x-rays and gamma rays that people think about. What Are X-rays and Gamma Rays?
What are the effects of UV radiation on the skin?
UV exposure is a powerful attack on the skin, creating damage that can range from premature wrinkles to dangerous skin cancer. Damage from UV exposure is cumulative and increases your skin cancer risk over time. While your body can repair some of the DNA damage in skin cells, it can’t repair all of it.
What kind of radiation does the Sun give out?
The sun naturally gives out ultraviolet radiation (UV), whilst the UV from sunbeds is artificial. There are 2 main types of UV rays that damage our skin. Both types can cause skin cancer:

What kind of skin cancer can you get from sunburn?
UV exposure that leads to sunburn has proven to play a strong role in developing melanoma, the most dangerous of the three most common types of skin cancer. Recent research shows that the UV rays that damage skin can also alter a gene that suppresses tumors, raising the risk of sun-damaged skin cells developing into skin cancer.
