When radiation facility for various unsealed radioisotopes intends to execute clearance of solid waste contaminated by only short half-life nuclide, a necessary strategy to prevent from contamination of long half-life nuclide has been shown in technical examination interim. We established our radiation facility as a model for classification management of nuclide according to length of half-life and examined the effectiveness of the classification management of the interim report as index nuclides, tritium and Phosphorus-32, based on the example of our classification management of the nuclide in facilities. In this report it was found that the classification management of the nuclide by half-life prevented effectively long half-life nuclide from mixing with the solid waste contaminated by only short half-life nuclide.
