The provincial nuclear station emergency response and the surrounding environment of nuclear power station is good, the radiation monitoring system is operating well, and the nuclear power station emergency response work is carrying out normally.
The No.2 unit of Da Yawan Nuclear Power Station and the No.1 unit of LinAo Nuclear Power Station are under good operation condition. The annual radioactivity nuclide emission is under national limit, is the lowest level in the past years. The environmental radioactivity level has no changes, compare with the condition before the nuclear station is operated.
As for the radiation monitoring done to the surrounding of the radiation waste storage( including ¦Ã radiation measurement, aerosol, soil, underground water, ground water, concentration of radon) showed no obvious changes occurred to the surrounding environmental radioactivity level.
The Environmental electromagnetism radiation mainly comes from communications, radio and television injection station and electrical transmission facilities. The monitoring results showed that provincial radiation level around most of the electromagnetism source are within national standard limit, belongs to positive wave communication injection station high level electromagnetism radiation level. Some of measurement points that are located near antenna are beyond national standards limit, and further supervision is needed. Inside the high-voltage electricity transmission and transformer system, the power frequency electric field intensity near the major transformer belongs to high level; some of the measurement points are beyond national limit.
a. Natural Preservation Region
By the end of 2002, Guangdong has set up 198 Natural Preservation Region, total area of 3.0087 million hectare, including land area 766.4thousand hectare, which is 4.31% of provincial land area.
b. Ecological Demonstrative Region
Deepen in the construction of ecological demonstrative region. Has set up 11 national ecological demonstrative region experimental units, including Zhuhai, Zengcheng, Longmen, Zhanjiang, Lianjiang, Zhongshan, Nanao, Shixing, Lianping, Xuwen and Jiexi. Guangdong EPB has examined and named 39 provincial ecological demonstrative regions. Till now, 106 provincial ecological demonstrative regions have been named, including 16 ecological demonstrative town, 53 ecological demonstrative villages, 10 ecological demonstrative farms and 27 ecological demonstrative gardens.
c. Control of area source pollution
Carry out the <Decision about speed up the development in mountainous district > issued by the provincial government, emphasize on the protection of drinking water source, agriculture production and natural resources. Increase the degree in the supervision management and pollution control in rural pollution source. Strengthen the management in birds and animal breeding industry, organized the control of breeding farms located in key river basin, and entirely demolished the breeding farms located in the drinking water source region.
