Hiroshima and Nagasaki

On 6th August 1945, an atomic bomb was dropped on Hiroshima by US air forces. This was the first time a nuclear weapon had ever been used; the fireball created by the bomb destroyed 13 square kilometres of the city, and those dead as a result numbered up to 180,000.

Three days later, a second atomic bomb was dropped on the city of Nagasaki, killing between 50,000 and 100,000 people.

The firestorm in Hiroshima destroyed 13 square kilometres (five square miles) of the city. Almost 63% of the buildings in Hiroshima were completely destroyed and many more were damaged. In total, 92% of the structures in the city were either destroyed or damaged by blast and fire.

Estimates of total deaths in Hiroshima have generally ranged between 100,000 and 180,000, out of a population of 350,000. Tens of thousands died immediately and many more in the days and months that followed.

The nuclear bombing did nevertheless prove devastating, with approximately 22.7% of Nagasaki’s buildings being consumed by flames, but the death toll and destruction was less than in Hiroshima. Estimates of casualties from Nagasaki have generally ranged between 50,000 and 100,000, with many dying instantaneously and others dying slowly and agonisingly as a result of burns and radiation.

As a science student it is very important to be aware about the harmful effects of nuclear war. For this we should impart scientific temper and knowledge to students.
