Best Answer: Good question. On average clouds reflect 60% of incoming solar radiation which includes short wave UV. The thicker the cloud the greater the reflection, from 60 - 90%. For thin clouds the albedo, or relection is 30 - 50%, which explains why we can still receive UV on cloudy days.

Beyond UV, comes the highest energies in the electromagnetic spectrum: X-rays and gamma rays. Our atmosphere blocks this light, so astronomers must rely on telescopes in space to see the x-ray and gamma ray universe.
