UV radiation is released from the sun.It is harmful for life.
The uv index
The UV Index is on a scale between 0-10(10 being the most harmful). With a UV index of +10 you need to use a really strong sun screen to block any harmful UV's that will come through. Constant exposier to +10 UV Index can cause permanent skin damage and worse case skin cancer. So get out your SPF 35 for that one and be safe in the sun.
Smog is created by the action of sunlight on pollutants so a smoggy day is a sunny day hence the higher UV index.
The Bank Rate Monitor Index deal with average interest rates paid to people based on their savings when they deposit it. It is based on 100 banks in the United States.
The UV index is ona scale of 0-10 (10 being the most harmful) Which means yes, 12 is harmful, so you would need a very strong sunscreen or a better choice would be to stay indoors.

Meteorologists use a little thingy called the UV index which measures the UV number and the exposure level to the number like say 0-2 would be a low exposure level showing that UV value isn't very high or 11+ which means a very high risk of exposure to UV rays meaning sunburn is more likely to happen than if it was 3-5 which is a moderate risk where you may get it but the chances aren't that high . note is say thingy because this isnt reliable :P kidding its true
