| Research Abstract |
In this study, the immobilization method for radioactive iodine using an inorganic nanocomposite sintered body (zeolite/apatite nanocomposite) have been developed. The iodine content in the nanocomposite was more than 5wt%. The iodine retention rate in distilled water was more than 99%. The nanocomposite sintered body fabricated by pressureless sintering method was well densified. This inorganic composite sintered body is a promising alternative to the common vitrification process.
