Survivors of the explosion still faced the danger of radiation poisoning. Most people who received high doses of radiation died immediately or on the first day. Additionally, the ability to deeply penetrate radiation into human skin has increased the rate of cancer and birth defects. Not only was the soil contaminated, the water sources, air and buildings also had traces of radioactivity. After the explosion, “black rain,” sticky, dark, irradiated water, was reported in Nagasaki. Even now, sixty years later, many side effects such as leukemia, atomic cataracts, thyroid cancer and birth defects remain...
