Understanding the magnitude of the Hiroshima atomic blast is difficult to imagine if it can't be put into perspective.The incredibly high number of casualties and injuries, including the ones exposed to radiation gives us only hints on the scale of the impact, which according to a report release by the US Army after the attack amounts to more than 130,000. In fact, according to the Princeton University Press , a nuclear explosion causes massive damage when the energy is released between the thermal radiation (35%), the blast (50%) and the nuclear radiation (15%).First a fireball expands while transforming all matter into gas at several million degrees. The vaporized matter condenses into a radioactive cloud and pressure waves start moving outwards forming the air blast, which, together with the heat wave wipes out everything in the bomb's range. On top of all this, the nuclear fallout impacts any living being in a wide surrounding area, affecting entire generations with its effects on the genetic patterns.To help understand the impact of a nuclear blast, the closest private approximation might be a simulator called Nukemap , which embarked on the task of providing us with context around the harm that such an event could cause.The website lets you select your city, pick a type of bomb and the way of delivery, and hit detonate. The map will show the blast radius broken down into fireball, air blast and thermal radiation area. The program will calculate the number of casualties based on how many people live in the selected city and the amount of injuries.The project is supported by the College of Arts and Letters at the Stevens Institute of Technology
