CFLs emit harmful levels of UV

[Quantum Windbag]

I wonder what all those science loving liberals are going to think about the massive outbreak of skin cancer in their future.

Inspired by a European study, a team of Stony Brook University researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs.
The results, "The Effects of UV Emission from CFL Exposure on Human Dermal Fibroblasts and Keratinocytes in Vitro," were published in the June issue of the journal of Photochemistry and Photobiology.
The researchers, led by Miriam Rafailovich, PhD, Professor of Materials Science and Engineering and the Director of the Garcia Center for Polymers at Engineered Interfaces at Stony Brook, conducted similar research to a European study on Light Sensitivity. Stony Brook researchers collected CFL bulbs purchased from different locations across Suffolk and Nassau counties, and then measured the amount of UV emissions and the integrity of each bulb's phosphor coatings. Results revealed significant levels of UVC and UVA, which appeared to originate from cracks in the phosphor coatings, present in all CFL bulbs studied.

If they're made by GE, it doesn't count

So you hate science?

I love science, but I do hate idiocy.

Because somebody else made those...

Is this any different from regular flourescent lights?

But the left intended well.

And that's all that matters.

 

[uscitizen]

Cracks in the coatings....

Hmm seems like a manufacturing quality issue to me.

I neither love nor hate science, I use it. Unfortunately, all the science loving liberals don't actually use science to make decisions because they all invested in woman's studies or gay and lesbian instead of real a education. they don't understand science, or how to use it to reach a valid conclusion, they just love it.

I have no idea. CFLs use a different technology because of the size, but I have no idea if that results in a difference in UV radiation. My guess is that, since people tend to sit closer to CFLs, the radiation is more concentrated. Most regular fluorescent are covered by a diffuser, which probably absorbs at least some of the UV they produce. That is just my gut speaking though, I could be wrong.

If you can figure out how to put an even coating on the inside of a CFL you would probably be able to retire with more money than Bill Gates tomorrow.

Oh okay, just wanted to make sure I wasn't missing a legitimate point there.

Certainly less exposure than playing in a 70s band in those "black light" caverns and clubs..
The bell-bottoms, shoulder length hair and long-sleeve paisley shirts probably saved my life...

Citation needed!

I am a liberal educated in a scientific discipline. What I see are internet warriors that had an introduction to science, to complete a college requirement, or worse, high school physics, think that they have the skill set to understand complex issues.

Guess what guys, you don't! You barely made it through a liberal arts education, cup cake.

On topic: my concern with the compact florescent bulbs is the 4μg of Hg. What is worse, the Hg, or the minute contribution of those bulbs?

Personally, Hg sux! I prefer some fraction of degree increase in temps.

Point is -- arrogant elitist SOB -- that I don't think we KNOW the extent of the UV exposure problem and WHETHER it's a valid health concern.. A REASONABLE person with even a minimal introduction to scientific reasoning and methods -- would WAIT for the data before LEAPING out and making embarrassing proclamations from on high..

Welcome to USMB -- you'll fit right in!!!

Funny how you love government scientists when they tell you what you want to hear.
