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.
Churchill Downs is the name of the racetrack where the Kentucky Derby is held. The historic racing of thoroughbreds always has been held at that particular racetrack in Louisvâ¦ille, Kentucky. But the track didn't always have the name that it currently has. It's original name was the Louisville Jockey Club Course.
