Scope
NB/T 20138-2012 is the English-translated version of 核电厂个人和工作场所辐射监测.
Individual and workplace radiation monitoring at nuclear power plants is the subject of NB/T 20138-2012, a recommended standard of the Chinese energy industry.
It sets out what has to be monitored for plant staff and for the workplace itself, the monitoring requirements and methods, how the results are to be interpreted, and the quality assurance and record keeping that go with them.
It is written for the radiation monitoring of personnel and work areas during normal operation and maintenance of a nuclear power plant, and operators of nuclear reactors other than power plants may take it as a reference.
Among the documents it cites are GB/T 14056.1-2008, GB/T 15222-1994, GB 18871-2002, GBZ 129-2002, GBZ 166-2005, EJ/T 1204.1, JJF 1059 and IAEA RS-G-1.3. Issued on 6 January 2012, it has applied since 6 April 2012.
