Alpha radiation is a type of energy released when certain radioactive elements decay or break down. For example, uranium and thorium are two radioactive elements found naturally in the earthâs crust. Over billions of years, these two elements slowly change form and produce âdecay productsâ such as radium and radon.
Before the big race, a two week Kentucky Derby Festival takes place with events for the whole family. Then, as usual, the race will take place on the first Saturday in May 2016. On the big day, the contenders will line-up to race around a 1.25 mile track.
The Kentucky Derby, which is considered the most recognized race in horse racing, occurs the first Saturday in May every year. The Kentucky Derby is restricted to 3-year-old thoroughbred horses, each horse running for the first time in their life at a distance of a mile-and-a-quarter.
