Final answer:
The 1945 bombing of Hiroshima resulted in radioactive soil contamination, with immediate human casualties and long-term environmental effects due to nuclear fallout and radioactive particles spread by the ensuing 'black rain'. Option 4 is the correct answer.
Step-by-step explanation:
The 1945 bombing of Hiroshima resulted in radioactive soil contamination. This historic event stands as a stark reminder of the devastating human and environmental impacts of nuclear warfare. When the Enola Gay dropped the atomic bomb known as "Little Boy" on the city, an immense heat blast melted materials, and the subsequent nuclear fallout resulted in the dispersal of radioactive material, manifesting as radioactive soil in and around the impact site.
This lethal pollution was not the conventional type that contributes to global warming or creates a dead zone; rather, it was a severe form of radioactive contamination that could remain in the environment for thousands of years, posing long-term risks to human health and the ecosystem. The immediate effects of the bomb incinerated or vaporized many people, while tens of thousands would later succumb to radiation poisoning.
The nuclear explosion also resulted in a "black rain" that further spread radioactive particles, exacerbating the environmental contamination. Reports from survivors and historical records provide a chilling narration of the immediate aftermath and the enduring legacy of soil pollution caused by the bombing.
