 Re: I metered the sun today
This may belong in the geeks with meters forum but I misposted it to begin with. What does it mean. Well a 7.0 meter reads the dose of UV light we divide 240 by the meter reading to determine the length of time it takes to get a maximum safe FDA dose. 5.0 and 6.0 meters measure different parts of the UV spectrum. Divide the amount of UVB by the total amount of UV to get percentage of UVB.
Many of the lamps sold have a listed UVB component whether it is 1.6 3.3 5.0 6.5 7.0 8.5 or 10% UVB causes our skin to produce pigment. UVA causes the pigment to oxidize and turn brown. The percent of UVB is not the last word of how powerful a lamp is 1.6% of 200 is more than 5% of 50.
I metered the sun because I was bored and curious. According to Solar Steve the sun on Saipan is nearly twice that of what it is here |
