Can anybody send me information about radiation effected progeny of Hiroshima survivors of recent days?

Question

We know that many of the survivors of Hiroshima bombing were genetically mutated, this mutation effect their progeny. I want to know is/are there any children born now a days with disablity of that mutation

Answer 1

Even under ideal conditions more than half of all pregnancies are spontaneously aborted because of genetic anomalies. Shortly after the U.S. began testing nuclear bombs in Nevada, studies showed an increase in the rate of such miscarriages... suggesting that most of the mutations would be weeded out in the next generation. Though attempts were made after the bombings of Nagasaki and Hiroshima to determine is similar patterns were followed, they were fraught with problems and no sound conclusions can be drawn.

Studies over a period of twenty years found no significant difference between children of survivors and any other children - they seem to be completely within normal ranges for birth weight, mortaility, and cancer-like diseases. The one exception is those children who were concieved but not born and thus exposed to radiation in utero. These children were particularly prone to brain damage and abnormal anatomical formations; tests measured their IQ as 5 points below average (link 1).

Given that most mutations are recessive, it would be normal not to see some of the consequences of genetic damage for two or three generations - time for those recessive traits to pair up in the children of the children. These kinds of things would only be beginning to appear right now, and could remain hidden for some time. There is virtually no current evidence, however, that any long-term genetic changes have occurred (link 3).

If you are looking for secondary effects from radiation you should look to America instead of Japan. Though two bombs were exploded over Japanese cities, hundreds were exploded in America and fallout from those explosions have been measured thousands of miles away. Further, production of nuclear materials and storage of nuclear waste has been a problem from the very beginning, with MANY cases of leaks. It is estimated that some of the most consistently irradiated people on Earth live in the neighborhood of Hanford, Washington, where waste dating back from the Manhattan Project is even now leaking into the ground water (link 2).
