Magnetic decontamination reagent

Magnetic decontamination reagent

We are developing a magnetic decontamination reagent as a new field.


Decontamination reagent for fly ash contaminated by radioactive cesium (Cs)

  • Joint development with Jikei University,School of Medicine ,DOWA Holdings and DOWA Eco-System

Fly ash decontamination flow

Magnetic decontamination reagent  Fly ash decontamination flow
  • Through stirring and washing for 3 to 6 hours, the radiodensity in the fly ash is reduced by about 85%.
  • The radiodensity of waste water (filtrate) is lower than the detection limit.
