What is UV and what does it mean for Dayborians.

 

A UV Index reading of 0 to 2 means low danger from the sun’s UV rays for the average person.

Wear sunglasses on bright days. If you burn easily, cover up and use broad spectrum SPF 30+ sunscreen. Bright surfaces, such as sand, water and snow, will increase UV exposure.

The UV Index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the earth’s surface.

It cannot be simply related to the irradiance (measured in W/m2) because the UV of greatest concern occupies a spectrum of wavelength from 295 to 325 nm, and shorter wavelengths have already been absorbed a great deal when they arrive at the earth’s surface.

Skin damage from sunburn, however, is related to wavelength, the shorter wavelengths being much more damaging. The UV power spectrum (expressed as Watts per square metre per nanometre of wavelength) is therefore multiplied by a weighting curve known as the erythemal action spectrum, and the result integrated over the whole spectrum.

This gave Canadian scientists a weighted figure (sometimes called Diffey-weighted UV irradiance, or DUV, or erythemal dose rate) typically around 250 mW/m2 in midday summer sunlight. So, they arbitrarily divided by 25 mW/m2 to generate a convenient index value, essentially a scale of 0 to 11+ (though ozone depletion is now resulting in higher values, as mentioned above).

A UV Index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure.

Stay in shade near midday when the sun is strongest. If outdoors, wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.

Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.

Bright surfaces, such as sand, water and snow, will increase UV exposure.

Dayboro Sun UV very high warning.

A UV Index reading of 8 to 10 means very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly.

Minimize sun exposure between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
