On cloudy days, approximately 20-30% of solar UV radiation can still reach the Earth's surface, which is close to the option of 22 percent. Therefore, the correct answer is **22 percent**. It is important to note that even on cloudy days, it is still possible to get sunburned due to UV radiation penetrating through the clouds.
