  • Sample 3 is treated water after raw water is passed through a fresh water generator.
  • Sample 4 is obsidian (rock containing 65 to 76% silicon dioxide) provided in the fresh water generator after the raw water is passed through the fresh water generator.
  • Sample 5 is tourmaline aluminum in the fresh water generator after the raw water is passed through the fresh water generator.
  • Sample 6 is an ion exchange resin in the fresh water generator after raw water is passed through the fresh water generator.
  • sample 6 in FIG. 39 ion exchange resin in the fresh water generator after the raw water is passed through the fresh water generator.
  • iodine 131 is 49 (Bq / Kg)
  • cesium 134 is 21 (Bq / Kg)
  • cesium 136 is “not detected”
  • cesium 137 is 27 (Bq / Kg)
  • cesium has three types.
  • the total was 48 (Bq / Kg).
  • sample 6 ion exchange resin in the fresh water generator after passing the raw water through the fresh water generator
  • sample 1 is more than sample 1
  • the numerical value increased by 10 to 61 (Bq / Kg). This measurement result is thought to be due to some error.
  • the error is assumed to be, for example, that the ion exchange resin or the container in which the ion exchange resin was put in was not correctly washed in the measurement performed before the sample 6 in FIG.
  • Materials used for the creation water generator include ion exchange resin 32, rock 54 (obsidian etc.) containing 65 to 76% silicon dioxide, tourmaline 46, and metal 48.
  • ion exchange resin 32 rock 54 (obsidian etc.) containing 65 to 76% silicon dioxide, tourmaline 46, and metal 48.
  • the radioactive substance may be attached only to the ion exchange resin 32. From the sample 6 in FIG. From this point, in order to reduce the amount of radioactive material from raw water in large quantities, it is only necessary to periodically replace the ion exchange resin, and to reduce or remove the radioactive material from the water containing the radioactive material efficiently over a long period of time. Can do.

Abstract

L'invention concerne un procédé pour diminuer une substance radioactive, qui permet l'élimination ou la diminution d'une substance radioactive d'une plante telle qu'un légume, d'une eau ou d'une terre telle qu'une terre agricole qui a été contaminée avec une radiation. Une substance contaminée par la radioactivité est immergée dans une eau particulière qui est d'abord passée à travers une résine échangeuse d'ions puis est passée à travers une parmi une tourmaline et une roche éruptive contenant du dioxyde de silicium dans une quantité de 65 à 76 % et ensuite à travers l'autre. De cette manière, les concentrations de radioactivité de l'iode-131 et de trois sortes de césium (césium-134, césium-136 et césium-137) dans la substance contaminée par la radioactivité peuvent être diminuées.
