can uvb pass through plastic
Oct 29, 2013. #16. Seiryu said: I personally just use the 10.0's (and more recently arcadia's) because the UVB output is still nothing compared to outside UVB and will not harm your animal period. 5.0's IMO, through a screen most times aren't producing enough UVB. I tested one the other day with my UV meter.Fortunately for your skin, car windows are rather effective at blocking UVB rays. However, according to the Skin Cancer Foundation, those same car windows do little to nothing to block the longer, UVA rays. These dangerous rays pass right through the glass in car windows, causing tanning, wrinkling, sagging, and premature aging of your skin. At one time or another, most of us have proved empirically, and painfully, the old mother's tale that it's possible to get sunburned on a cloudy day. On average, clouds do reduce the amount of ultraviolet A and B radiation that reaches the Earth's surface and our skin, but it far from stops the damaging rays. Indeed, clouds are generally better Sep 21, 2012. #3. UVB cannot pass through any type of solid objects, but does bounce off surfaces. Depending on the thickness of the weave and the weave ratio of the screen can block anywhere from 20-50% of the UVB. As BeBoSON said, it isn't much to worry about and as long as you're providing the correct/recommeded amount of calcium with D3
According to these standards, a plastic product can be “compostable-labelled” if at least 90% (weight) disintegrates into particles that pass through a 2 × 2 mm mesh within 3 months andScientists found that incorporating sugar units into polymers makes them more degradable when exposed to UV light. Many plastics that are labelled as biodegradable are only compostable under Fortunately, Polyplastics and TOPAS Advanced Polymers provide a line of glass-clear, medical grade plastics with high UV transmission so that tests utilizing UVA, UVB, and with the right grade, even UVC down to 220nm can be carried out with confidence. No other plastic material can deliver this level of UV transparency. Pure and Clear Do UV Rays Go Through Glass? The answer is a little bit complicated. Not only are there different sorts of glass with different properties, but there are different sorts of UV light, too. Shorter-wavelength UV-B rays are easily excluded, but longer-wavelength UV-A rays can easily pass through a normal glass window. That’s right. The ozone layer blocks 100% of these rays from getting through. Otherwise, we’d be in trouble, because they can do serious damage. UVB. Like UVC rays, the Earth’s ozone layer impedes UVB rays – just not entirely. About 10% of UVB rays pass through the ozone layer and reach us.

Mesh and Screen in the Vivarium. Anything that is placed between the lamp and the reptile will absorb a percentage of the UVB. Ordinary glass will absorb 99-100% of the UVB; most plastics will absorb almost all. It is therefore very important that there is no plastic or glass between the bare tube and the reptile.
3. You can't see or feel UV, but your skin will fry if exposed too long, and paper, artwork, fabrics, and other materials will degenerate from exposure. 4. IR is heat, and we can capture heat images in a CCD or IR film - way cool to see. 5. IR can penetrate opaque material. UV cannot. 6. Visible light transmission through clear Plexiglas is 92%.
