Wu Xiaoqing said, "According to the conclusion of our experts, the four cases of leakage have not had any negative impact on the environment."

Three of the 15 remaining radiation sources are buried under rubble, while the other 12 are located in unstable buildings technicians still cannot enter safely. The ministry has asked the local government to speed up efforts to clear away the debris.

The Environment Ministry has also sent experts to Sichuan and its neighboring regions to keep a close eye on the environment. It has raised 50 million yuan for new monitoring equipment.

Meanwhile, environmental officials say air quality is normal in 11 of the worst-hit counties and towns.

As a precautionary measure, the ministry is urging workers in the quake zone to sterilize all animal carcasses before burying them, and to watch out for any disease outbreak among the livestock.
