Records of the nuclear industry in China covering the past 30 years indicate that the nuclear industry has a good safety record and negligible impact on the environment.
Since the late 1970s the doses received by workers in the nuclear industry have declined.
Average annual doses to all workers, except uranium miners, from occupational radiation exposure have been below about 3 mSv, and the percentage of workers receiving doses exceeding the annual dose limit of 50 mSv has been less than 0.3%. The average annual dose received by underground workers has dropped below 20 mSv.
The doses to the critical groups in the nuclear facilities have all been lower than 1 mSv.
Epidemiological investigations showed that there was no significant carcinogenic effect except in the case of uranium geological sectors and mines, and no acute lethal accidents have occurred nor acute radiation disease been found in the nuclear industry.
In view of radiation protection optimisation, the normalised collective dose, namely the collective dose delivered for production or 1 unit of end products, is still high, especially in uranium mines where both the occupational radiation exposure and the exposure of the public are still higher than the typical values reported internationally.
