How are UV rays measured?

In: Medical Technologies, X-Ray [Edit categories]

Answer:

There are different ways to measure UV radiation. The mosty common one is by using an index number, which gives the approxiate danger level for humans. This index number is a result from taking different wavelengths into account, shorter wavelengths being more dangerous to cell structure than longer ones.

A better way however is to give the mW/(nm m²) (milliwatt per square meter per nanometer of wavelength).

For the exact calculations and more information, see:
