The Power of the Atomic Bomb



The detonation of the atomic bomb created a fireball that blazed like a small sun. More than a million degrees Celsius at its center, the fireball reached a maximum diameter of 280 meters in one second. Surface temperatures near the hypocenter rose to 3,000-4,000.
Fierce heat rays and radiation burst out in every direction, expanding the air around the fireball and creating a super-high-pressure blast. These factors interacted in complex ways to inflict tremendous damage.
Although the casualties inflicted by the atomic bombing are not precisely known, approximately 140,000 people are believed to have died by the end of 1945. Buildings within a two-kilometer radius of the hypocenter crumbled and burned to the ground.
