Other Interesting Nuclear Facts

 

The power of nuclear devices is measured in kilo tons.

A 1 Kilo ton bomb would have the same destructive power as a 1000 tons of TNT

To give you an idea of how big 1000 tons of TNT actually is, think about this.

A 1000 tons of TNT , if packed onto cargo crates or pallets and stored 3 boxes high, would stretch approximately 200 miles.
