Both UVA and UVB rays can cause damage to your skin. Sunburn is a sign of short-term overexposure, while premature aging and skin cancer are side effects of prolonged UV exposure.

YK-35UV. UV Light Meter, 290 to 390nm. 1. Firstly, UVB radiation and vitamins also generate singlet oxygen. Secondly, UVB radiation may change the chemical structure of vitamins that may change the role of such endogenous photosensitizers in UVA mediated mechanisms.

UVA absorberes ikke i atmosfæren, men det spredes som andet lys og når altså heller ikke usvækket frem til Jordens overflade. UVB This is the mid range (mid strength) UV wavelength for use in general UV curing. UVB is made right under the UVA and is has very similar uses like the UVA. UVB spans the 280 to 320 nm range. UVB is a mid-range wavelength that works with many of the photo initiators in use today. UVB cures the “middle area” on most UV formulations. UVA, UVB, UVC- all of these are forms of ultraviolet light rays that are naturally occurring, but they are not created equal.

Traditionell reicht der UV-Bereich von 380 bis 100 nm und wird mit Blick auf die Transmission atmosphärischer Gase in die Unterbereiche UV-A, UV-B und UV-C eingeteilt, siehe Tabelle. Die „unrunden“ Grenzen haben folgende Bedeutung: 380 nm ist die Empfindlichkeitsgrenze des menschlichen Auges.

UVA vs. UVB Damage. To understand why the effects of UVA and UVB differ, note that the different subtypes of ultraviolet radiation are classified according to their wavelengths, frequencies, and the photon energy they carry.

Most UVA radiation is able to reach the earth's surface and can contribute to tanning, skin aging, eye damage, and immune suppresion. UV 400 Protection lenses are engineered to block 100% of all harmful blue light up to 400 nanometers; UVB wavelengths(280-320 nm) are strongly affected by

UVA has generally been considered innocuous, partially because DNA does not absorb appreciably in this region, but UVB radiation (290-320 nm) has widely been considered to be the major etiological factor in human skin carcinogenesis caused by solar uv radiation, largely because DNA absorbs photons of UVB, which is known to produce thymine photoproducts (cyclobutane dimers and adducts).

UV 400 Protection lenses are engineered to block 100% of all harmful blue light up to 400 nanometers; UVB wavelengths(280-320 nm) are strongly affected by Consequently the value of the ratio of solar UVA/UVB should be considered as equal to 20 for studies in photobiology and photomedicine.

UVB phototherapy was formerly provided as a broadband source (290 to 320 nm). Both UVA and UVB rays are capable of damaging your skin.

strålningens toppvärde ligger i intervallet 315–400 nm (UVA) eller 280–315 nm (UVB).” Last Update: 2014-11-10. Usage Frequency: 1. Quality: Be the first to

Because of this, UVB light is often cited as the source that causes sunburn. For phototherapy, irradiation devices emitting either predominantly middlewave UV (UVB, 290-315 nm) or longwave UV (UVA, 315-400 nm) radiation are employed. In former years, patients were treated with broad-band UVB, broad-band UVA, or combination regimens.
