Answer:
Fallout is the radioactive particles that fall to earth as a result of a nuclear explosion. It takes around 10 seconds for the fireball from a nuclear explosion to reach its maximum size, but the effects last for decades and span across generations. Five to six years after the bombings, the incidence of leukaemia increased noticeably among survivors. After about a decade, survivors began suffering from thyroid, breast, lung and other cancers at higher than normal rates.
Explanation:
Nuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. By the end of 1945, the bombing had killed an estimated 140,000 people in Hiroshima, and a further 74,000 in Nagasaki. In the years that followed, many of the survivors would face leukemia, cancer, or other terrible side effects from the radiation. Pregnant women exposed to the bombings experienced higher rates of miscarriage and deaths among their infants; their children were more likely to have intellectual disabilities, impaired growth and an increased risk of developing cancer. And for all survivors, cancers related to radiation exposure still continue to increase throughout their lifespan, even to this day, seven decades later.
