The blast radius of a 250 gallon propane tank would be 100 yards
standard blast radius is around 3-8 feet
30 miles.
35km
The fireball was roughly 1500 feet in diameter (750 feet in radius).Blast damage was found at 10000 yards (30000 feet) to some of the bunkers.The blast was heard hundreds of miles away.
square miles and radius have different units
About 16 ft for effective use.
150 yards
Arrow - 2012 Blast Radius 2-10 is rated/received certificates of: Netherlands:12 USA:TV-14
It has a blast radius of 160m to 250m. The bomb weighs 5 kg containing 1.2 kg of HE. The missile is 11.2 m long and has a diameter if 0.88m.
The hand grenade currently employed by most armies has a kill radius of 5 meters and danger radius of 15 meters.
Well i did some rough estimates...prob be like 56 milesA blast radius is equal to the square root of the megatonage. A 1 megaton bomb has a blast radius of severe damage of about 4 miles. Therefore a 200 megaton bomb (14 being about the square root) would have about a 56 mile radius. Though direct exposure to the explosion at that distance could probably still cause severe burns and it would probably cause damage as much as 200 miles out.
