Radiation Dose measured at exhaust stack monitor of Additional Miscellaneous Solid Waste Incinerator Building
The following is the radiation doses of the exhaust air released from the exhaust stacks measured by the exhaust stack monitors in the Additional Miscellaneous Solid Waste Incinerator Building on the premises of Fukushima Daiichi Nuclear Power Station.
Monitoring points
Radiation dose
Radiation dose
- * Wind direction and wind speed are measured at the same level as the top of the exhaust stack by the weather measuring device on the west side of the off-site parking lot.
- * In case of heavy rain, wind direction and wind speed may not be measured accurately.
- * In the case that wind speed is less than 0.5 m/s, wind direction is shown as “-“ and wind speed is shown as “CALM”
- * From October 1st, 2024, location of the weather measuring device has been changed from the west side of the seismic isolation building to the west side of the off-site parking lot.

Exhaust stack of the Additional Miscellaneous Solid Waste Incinerator Building
Exhaust stack of the Additional Miscellaneous Solid Waste Incinerator Building is a facility to release the exhaust gas generated when waste is incinerated by the incinerator and the air inside the building. Radioactive materials in the released exhaust gas and in the air are removed through filters to mitigate their impact on the environment.
Incinerator dust monitor
Incinerator dust monitor is an equipment to measure the radiation dose contained in the dust in the exhaust gas released to the environment from the Additional Miscellaneous Solid Waste Incineration Facility .
Incinerator raregas monitor
Incinerator raregas monitor is an equipment to measure the radiation dose in the exhaust gas released to the environment from the Additional Miscellaneous Solid Waste Incineration Facility.
Measurement unit: cps (count per second)
1 cps means that 1 radiation ray was measured in 1 second by a radiation counter.
