Beijing denies smog is linked to nuclear radiation- as it prepares for new wave of pollution

A new batch of smog will hit the Beijing-Hebei (河北)-Tianjin (天津) area from Tuesday, the environment ministry predicted yesterday – as it dismissed online rumours linking the pollution to nuclear radiation.

Frequent winds from the north brought blue skies back to Beijing throughout last week, in a welcome change from the heavy pollution that had dogged much of December.

But the smog is expected to return and cover the middle and southern parts of the Beijing-Tianjin-Hebei cluster as well as parts of Shandong (山東), Shanxi (山西) and Henan (河南) provinces, according to a nationwide smog forecasting platform launched by the ministry on January 1.

It predicted cold fronts would hit the region on Thursday and clear the smog away.

Luo Yi, who oversees environmental monitoring by the ministry, said it had successfully forecast the air quality ahead of major political and social events, such as an APEC meeting in November and a military parade in September.

The persistent recent smog has revived a theory that first went viral online in 2013, when a self-described physician claimed it was the result of burning coal that contained high levels of radioactive substances including uranium.
