Measurement status of radioactive material concentration and air dose at waste incineration plants
Last updated on September 14, 2023.
Measurement results
- The survey was completed in March 2017 for exhaust gas, coagulated sediment sludge, reused water, and effluent, as the concentration of radioactive materials continued.
- Since the concentration of radioactive material incinerated ash generated at waste incineration plants continues to be below 100 Bq/kg (the national landfill standard is 8,000 Bq/kg), the measurement was completed in March 2019, together with air doses at incineration plants (near the fly ash treatment site).
Changes in the concentration of radioactive materials in main ash (total of Cs-134 and Cs-137)
Changes in radioactive material concentrations of fly ash (total of Cs-134 and Cs-137)
※The lower limit of quantification for Cs-134 and Cs-137 is 20Bq / kg. If the value is less than the lower limit of quantification, each value is added as 0Bq / kg.
