Nuclear facilities in the affected area have been confirmed to be safe, the ministry of environmental protection's Nuclear Safety Department said, Xinhua has reported.
China has a research reactor, two nuclear fuel production sites and two nuclear weapon facilities in Sichuan, all between 60-145km (40-90 miles) from the epicentre, according to the French Institute for Radiological Protection and Nuclear Safety.
Persistent rain compounded the misery for millions of people made homeless by the quake. And the weather may deteriorate, with rains turning torrential later in the week, potentially triggering landslides, Chinese forecasters said.
And the World Health Organization warned that rising temperatures in Sichuan, combined with a lack of clean water and waste disposal, and cramped conditions in makeshift camps, could be conducive to outbreaks of disease.
