Environmental Radiation Monitoring

​​​​​​​​

How are releases monitored

External monitoring stations register measurements of gamma radioactivity in ambient atmosphere on a continuous basis.
These monitors are located both within the nuclear power station (at 5 different locations) and at about 5 km from the power station at Bagang, Lingao,Yangmeikeng, Shuitou and Dapeng.
Air samples are continuously collected on filters. Filters are then replaced and measured daily for radioactivity.
Samples of underground water are also taken and analysed on a monthly basis.​
