I believe they were both harmed by nuclear radiation. Hiroshima was when the USA bombed Japan with a nuclear bomb. Chernobyl is the disaster in which a reactor caught fire and caused the harmful radiation to spread. I hope that was helpful. :)
70 years ago the Japanese cities of Hiroshima and Nagasaki were the target of two atomic bombs dropped by the United States that caused enormous devastation and destruction. Some 350,000 people lived in Hiroshima. It is estimated that the bomb that fell on August 6, 1945 killed some 80,000 people. Almost 80% of the buildings were destroyed or severely damaged. The total number of deaths in the city is still disputed, due to the injuries suffered in the explosion or the effects of radiation, but the figure varies between 90,000 and 166,000. Today, 1,174,000 people live in the city.
In the early morning of April 26, 1986 occurred what has been described as the worst nuclear disaster in history. One of the four reactors of the Chernobyl plant in Ukraine, which was then part of the Soviet Union, exploded and caused a fire that released huge amounts of radioactive particles into the atmosphere. As a direct result of the accident, 31 people died. But the long-term effects of radiation, such as cancer between generations, continue to be investigated. After the accident, an Exclusion Zone of 30 kilometers was decreed around the nuclear plant, which covers an area of approximately 2,600 km2 in the Ukraine, where radioactive contamination remains and where access is restricted.
In the 1930's Japan went to war with China. The United States supported China and placed a trade embargo on Japan so they couldn't get any supplies from the United States, particularly oil that might fuel Japan's military conquests.<span />
