98% of radioactive waste is "safe" after 40 or so years. After 40 years the radiation is 1/1000th of its initial waste state. The 1,000 - 10,000 year period generally cited is for the radioactive products to decay back to their original ore's radioactive intensity.

Yes. Would you rather die now or have a 10% increased chance of developing a cancer that may or may not be treatable 10 years from now?
