What are the main uses of ultraviolet radiation?
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. Different UV wavelengths and intensities are used for different purposes.
What are the three types of UV radiation and the characteristics of each?
UV radiation is classified into three primary types: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These groups are based on the measure of their wavelength, which is measured in nanometers (nm= 0.000000001 meters or 1×10-9 meters).
What is an example of ultraviolet radiation?
Ultraviolet radiation or UV radiation comes from the sun in sunlight. About ten percent of the total light output of the sun consists of ultraviolet radiation. Tanning beds and lamps also emit ultraviolet radiation. Tanning lamps and beds are also sources of UV rays.”
What is the characteristics of ultraviolet ray that makes it harmful to some extent when one is exposed to it?
Unlike X-rays, ultraviolet radiation has a low power of penetration; hence, its direct effects on the human body are limited to the surface skin. The direct effects include reddening of the skin (sunburn), pigmentation development (suntan), aging, and carcinogenic changes.
What is ultraviolet A and B?
On the electromagnetic spectrum, UV light has shorter wavelengths than visible light, so your eyes can’t see UV, but your skin can feel it. Ultraviolet A (UVA) has a longer wavelength, and is associated with skin aging. Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning.
What are sources of ultraviolet radiation?
Ultraviolet (UV) radiation is a form of electromagnetic radiation that comes from the sun and man-made sources like tanning beds and welding torches.
What are the advantages and disadvantages of ultraviolet radiation?
Now, let’s discover the pros and cons of UV radiation.
| Pros | Cons |
|---|---|
| 1. Stimulate Vitamin D production which helps to vitalize bones, muscles and immune system. | 1.Skin damages – Wrinkles – Loss of elasticity due to collagen destruction by the UV rays -Dark spots -Pigmentation -Skin cancer |
What are the harmful effects of UV rays?
Health Effects of UV Radiation
- Skin cancer (melanoma and nonmelanoma)
- Premature aging and other skin damage.
- Cataracts and other eye damage.
- Immune system suppression.
What are ultraviolet radiation How are they detected?
Detection: If the different radiations from the red part of the spectrum to the violet end and beyond it are made incident on the silver-chloride solution, it is observed that from the red end to the violet, the solution remains almost unaffted.
What is the difference between UV A and UV B radiation?
What is the range of UV radiation?
100-400 nm
The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm).
What are the effects of ultraviolet radiation on human health?
Human health-related effects. The impact of ultraviolet radiation on human health has implications for the risks and benefits of sun exposure and is also implicated in issues such as fluorescent lamps and health. Getting too much sun exposure can be harmful, but in moderation, sun exposure is beneficial.
What is UVC radiation and how dangerous is it?
A: UVC radiation is the highest energy portion of the UV radiation spectrum. UVC radiation from the sun does not reach the earth’s surface because it is blocked by the ozone layer in the atmosphere. Thus, the only way that humans can be exposed to UVC radiation is from an artificial source like a lamp or laser.
What are the different types of UV radiation?
Scientists studying astronomical objects commonly refer to different subdivisions of ultraviolet radiation: near ultraviolet (NUV), middle ultraviolet (MUV), far ultraviolet (FUV), and extreme ultraviolet (EUV). NASA’s SDO spacecraft captured the image below in multiple wavelengths of extreme ultraviolet (EUV) radiation.
What is ultraviolet radiation and how is it produced?
What is ultraviolet radiation? Ultraviolet radiation is the portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region. How is ultraviolet radiation produced?
