How does an atomic bomb blast cause skin to melt away?and how does it cause development of cancer?

Question

i need this to do a very important project ... therefore pls help if possible.
Thanks.

Answer 1

Demaging Effects of the Atomic Bomb
Thermal Heat. Intense thermal heat emitted by the fireball caused severe burns and loss of eyesight. Thermal burns of bare skin occurred as far as 3.5 kilometers from ground zero (directly below the burst point). Most people exposed to thermal rays within 1-kilometer radius of ground zero died. Tile and glass melted; all combustible materials were consumed.

Blast. An atomic explosion causes an enormous shock wave followed instanteneously by a rapid expansion of air called the blast; these represent roughtly half the explosion's released energy. Maximum wind pressure of the blast: 35 tons per square meter. Maximum wind velocity: 440 meters per second. Wooden houses within 2.3 kilometers of ground zero collapsed. Concrete buildings near ground zero (thus hit by the blast from above) had ceilings crushed and windows and doors blown off. Many people were trapped under fallen strunctures and burned to death.

Radiation. People exposure within 500 meters of ground zero was fatal. People exposed at distances of 3 to 5 kilometers later showed symptoms of aftereffects, including radiation-induced cancers.

Extremely intense heat and radiation. That's about it in a nutshell~

Answer 2

"Catrme" forgot to tell you that the thermal heat is at over twenty- three thousand degrees Fahrenheit (23,000) that's right, it atomizes the entire body instantly to gas, it's basic gases, at gouund zero.
