Infrastructure construction has been facilitated to a great extent.

No abnormal radioactive nuclide was found in the media. The complete absorbing dose for R radiation on land was in the range of natural background level. power frequency electric field and power frequency magnetic field, as well as electric field strength were in the range of natural background level.
Supervision on ambient radiation has been strengthened. Several local regulations, rules and standards regarding ambient radiation have been formulated which formed a consolidated basis for relevant law enforcement. Key enterprises, accounting for 85% of the total sewage discharge in the city, have installed on-line monitoring facilities.
