BS IEC 60951-2:2009

This standard BS IEC 60951-2:2009 Nuclear power plants. Instrumentation important to safety. Radiation monitoring for accident and post-accident conditions is classified in these ICS categories:

• 17.240 Radiation measurements
• 13.280 Radiation protection
• 27.120.20 Nuclear power plants. Safety

IEC 60951-2:2009 provides general guidance on the design principles and performance criteria for equipment for continuous off-line monitoring of radioactivity in gaseous effluents and ventilation air used in nuclear power plants for accident and post-accident conditions. General requirements for technical characteristics, test procedures, radiation characteristics, electrical, mechanical, and environmental characteristics are given in IEC 60951-1. These requirements are applicable in this part unless otherwise stated. The main technical changes with regard to the previous edition are as follows:
- clarify the definitions;
- up-date the references to new standards published since the first edition;
- update the units of radiation.

This publication is to be read in conjunction with IEC 60951-1:2009.
