Ultra violet class A and B radiation
There is no such thing. The two are adjacent, in other words, the range for UVB starts where UVA ends.
I am trying to fade the dye in fabrics with common UV lights, like that of tanning bed bulbs. There are options with amounts of both UVA and UVB. I am after a result with the highest degradation. Is UV degradation and Phototendering to dyes mainly from UVA or UVB? Would the level of degradation be higher faster with more UVA or UVB? Not really talking about what would be 'dagerous', besides UVB creates cancer so I would have thought that much more dangerous then UVA...
There are 2 types of ultra violet rays, UVA and UVB. UVA causes aging and wrinkles, and UVB causes the sun burns.
no,You need both uva and uvb light
There are three types of rays- UVA, UVB and UVC. UVB and UVA act differently upon our skin and do not equally damage it. The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays. The UVA rays are longer so reach the inner state of the skin and causes skin damage.
UVC UVB UVA
UV radiation is very harmful in many ways, first off they are invisible rays that come from the sun, UV radiation is made of ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These rays burn skin and cause cancer. UVB and UVC penetrate the ozone layer. UVA and UVB cause skin cancer, for this reason, sunscreens are recommended that block UVA and UVB.
UVA and UVB
A sunscreen protects you from getting darker if it says 'broad spectrum' while the UVA/UVB sunscreens prevent ultraviolet light from reaching your skin.
it means that our protection from UVA/UVB is lessened
Both UVA and UVB light is used for phototherapy of cutaneous T-cell lymphoma; UVA is usually administered once a week, and UVB can be weekly as well, or sometimes daily.
You can purchase car polishes and waxes that claim to add UVA and UVB protection in addition to protection from other contaminants to your automobile. These products include Simoniz 17106 and Turtle Wax T-27R F21 Liquid Car Polish. It should be noted that there are those who believe that that these product claims are false and that there are no products that offer significant UVA/UVB protection. Some car polishes offer uva/uvb protection for the automobile but not all. The sun can be very damaging to the paint on your car so a good polish or wax is important.
