A new research showed that, even though the cancer risks are permanent for the survivors, there are no other significant health effects. Moreover, the difference is life expectancy between the survivors and the rest of the population is just 1.3 years.
The study shows that the survivors have a lifetime risk for cancer indeed, but the author of the analysis approximated that the danger is similar to that of people who smoke.
The explanation may be the fact that the horror or the war and the massive kill following the bombing made people fearful when they thought about the impact of radiation on human body.
Nonetheless, the study shows that the atomic bomb killed only in the few days after the explosion. Ten years after, the risk for leukemia dropped to almost zero. On the other hand, the cancer risk remains for each of the survivors just as high, with the mention that their life expectancy is not dramatically different from the ones in the people that had not been exposed to the bombing.
The Radiation Effect Research Foundation that had been studying a group of 100,000 survivors said that the solid cancer risks remained just as high as at the beginning, and the people that witnessed the explosion will be in danger of developing the disease at any time during their life.
When it comes to the children of the survivors, the team of Japanese and American scientists that monitored the group since the late 1940s confirms that no evidence of genetic mutations had been observed.
Out of the 94,000 people included in the monitoring, 54,000 were at less than 2,500 meters from the center of the explosion. Two years after the bombing, the Japanese government organized a census and determined that 280,000 individuals had been exposed to the radiation of the two atomic bombs.
The health study includes a group of children who were victims of in utero exposure to the radiations and the second group of children who had been born in Nagasaki or Hiroshima between the 1st of May 1946 and 31st of December 1948.
The Japanese-American research organization performed a mortality follow-up, monitored the cancer diagnosis, sent out surveys to the survivors concerning their lifestyle.
A subset of the adult survivors had been medically assessed every two years, and almost 50,000 children had been examined for blood proteins and chromosome aberrations.
The survivor group has now an average age of around 74 years, and they represent 40% of the people who enrolled in the study more than 60 years ago.
