This paper has evaluated the safety of ultimate disposal of solidified radioactive wastes into the ground. It was assumed that ten percent of radionuclides contained in the waste was eluted into the ground by accident. Migration rates of radionuclides in the ground, the dispersion of nuclides in the sea, concentration of nuclides in the seafood, and radiation dose to the human environment due to disposal of radioactive wastes into the ground have been estimated.
The evaluation has shown that, under assumed conditions, this method of disposal was safe and promising.
