Arnold, B.S.. Answer. According to multiple sources (NASA, FDA, and others) here are the wavelengths of the UVA, UVB and UVC regions:
UVB penetrates and damages the outermost layers of your skin. Overexposure causes suntan, sunburn and, in severe cases, blistering. UVB is connected to the Sun Protection Factor (SPF) on labels of sunscreen products. The SPF number tells you how long the sun’s radiation (including some of the UVA) would take to redden your skin when using that product compared to the time without sunscreen.
2017 Apr 24;22(4):668. doi: 10.3390/molecules22040668. 2019-01-28 · UVA. Long wave (315nm to 400nm) Safe for general use. Used to detect counterfeit notes. Also used to charge up Glow and UV products. UVB. Medium wave (280nm to 315nm) Mixture of UVA and UVB. Can be found in tanning beds. UVC. Short wave (100nm to 280nm) Produces dangerous rays.
The UV spectrum is divided into: UVA 315 to 400 nm; UVB 280 to 315 nm; UVC 200 to 280 nm; Vacuum UV 100 to 200 nm UVC ranges from 200-275nm, UVB ranges from 275-320nm, UVA ranges from 320-400nm. In order to accurately measure the ultraviolet intensity, the response band of the instrument and the ultraviolet band should match. Linshang LS125 UV light meter can be equipped with 9 probes, which can measure UVA… UVA, UVB, and UVC lighting With fear and concern permeating the business world, you need the very best and most knowledgeable professionals to analyze and manage your lighting needs to most effectively reduce or mitigate risks associated with Covid-19 or any other virus that might infect your environment, staff, or employees. Hospital Grade UVC/UVB Test Card Plus UVC Sensor Card,Easy Measures & Quickly to Detect UVA/UVB/UVC Light Indicator Card,Reusable Detections, A Efficient Tool Used to Verify All Light Device 3.8 out of 5 stars 7 Similarly, the 3,5-diCQA was induced in UVA and UVB treatments at levels of ~4.60 mg/100 g, while p-coumaric acid derivative and HBA derivative were only present in UVB and UVC but not in UVA. The specific AOX increased as UV radiation time increased ( Table 1 ), which indicates that wounding stress combined with UV exposure induced phenolic compounds with more AOX capacity [ 30 ].

While UVB radiation is widely recognized for its harmful effects on human skin and links to skin cancer, each of the UV bands (UVA, UVB and UVC) create different risks for humans.

UVA, UVB and UVC Light Enhances the Biosynthesis of Phenolic Antioxidants in Fresh-Cut Carrot through a Synergistic Effect with Wounding. by. Bernadeth B.
Sunce zrači ultraljubičasto zračenje u području UVA, UVB i UVC. Zemljin ozonski omotač zaustavlja 97 % – 99 % Sunčevog ultraljubičastog zračenja, u području UVA i UVB, da stigne do površine Zemlje. UVB, UVA a UVC paprsky jsou součástí ultrafialového záření, které cestuje směrem k Zemi ze Slunce. UVC paprsky jsou pohlceny ozónovou vrstvou, takže se jich nemusíme bát. UVB & UVA paprsky oproti tomu doputují až k zemskému povrchu, a proto potřebujete opalovací krém. UVB paprsky jsou blokovány v atmosféře pouze částečně. UVA: UVA radiation is less hazardous than UVB radiation but is also significantly (approximately 1000 times) less effective than either UVB or UVC radiation at inactivating other SARS viruses.
