Data Descriptions：
- Radiation Monitor - Real-time radiation monitoring from dilution/discharge facilities confirms that radiation levels from radionuclides other than tritium remain within the normal range. The unit of measurements is counts per second (CPS).
- Tritium Concentrations After Dilution - It is calculated using the real-time flow, ensuring the diluted concentration below 1,500 Bq/L, in accordance with the operation limit.
