Will the people exposed to radiation become mutated (Japan)?

Question:

Will the people who were exposed to extreme amounts of radiation become mutated, what about their offspring (not yet conceived) or if a pregnant female was exposed to radiation? Or will they just develop diseases?



What made me think of this was that Hills Have eyes movie, I don't remember it that well but the people in it were all mutated &....

Answer:

If the workers are exposed to high amounts of it they might mutate at a cellular level (cancer) but visible mutations like extra limbs, lack of eyes, and underdevelopment won't happen until the next generation is conceived by those affected by the radiation. The most likely case is that some workers will develop Radiation Sickness and will have to be treated.
