| titleOfInvention | Method for producing reclaimed granulated crushed stone from soil containing residues containing naturally occurring radioactive materials including thorium or uranium |
| abstract | The present invention provides a method for producing a regenerated granulated crushed stone that can be reused from a residue or soil containing a naturally occurring radioactive substance. The present invention includes (a) a step of producing a raw material by uniformly mixing a predetermined amount of soil containing a residue containing a naturally occurring radioactive substance, and (b) radiation of the naturally occurring radioactive substance. A step of mixing a raw material having an active concentration of less than 2000 Bq / kg and a predetermined additive of substantially the same amount to produce a pre-granulated mixed raw material having a radioactivity concentration of less than 1000 Bq / kg, and (c) before granulation Adding a cement, water and an insolubilizing material to the mixed raw material and granulating the mixture to produce a granulated product having a particle size of 5 mm or more; (d) 70 to 90% by weight of recycled concrete (RC And 40) mixing a granulated product of 10 to 30% by weight to produce a granulated regenerated crushed stone having a radioactivity concentration of 100 Bq / kg or less.
