BS IEC 61559 is an International Electrotechnical Commission standard on radiation protection instrumentation in nuclear facilities that discusses the requirements for centralized systems for continuous monitoring of radiation and/or levels of radioactivity to ensure protection against radiation hazards.
BS IEC 61559-1 is the first in the BS IEC 61559 series that applies to centralized systems intended for continuous monitoring of radiation and/or levels of radioactivity installed in nuclear facilities, primarily in support of radiological protection in the working areas.
BS IEC 61559-1 applies to centralized data processing systems, data links, and equipment sitting and layout.
BS IEC 61559-1 also applies to indications displayed locally and centrally. BS IEC 61559-1 applies to normal monitoring functions.
Note1: BS IEC 61559-1 does not apply to criticality alarm systems.
Note2: BS IEC 61559-1 does not directly apply to the design and testing of detection and measurement assemblies. These should, wherever practical, conform to relevant IEC specifications.
BS IEC 61559-1 on the requirements for centralized systems for continuous monitoring of radiation is useful for:
A centralized system for continuous monitoring of the radiation levels in nuclear facilities is composed of appropriate devices for measurement, acquisition, processing, display, and storage of data. The data is related to the detection or measurement of ionizing radiation and, more generally, to the radiological safety of facilities, premises, and their surrounding environment. By monitoring the status of the nuclear facility, the centralized system provides confirmatory information on the maintenance of a satisfactory working environment and provides a display of any developing long-term trends.
BS IEC 61559-1 provides you with guidance on the specification, operation, and testing of computers for the centralized monitoring function, general characteristics, general test procedures, radiation, electrical, safety, and environmental characteristics and the identification certificate for the systems, etc.
The requirements provided by BS IEC 61559-1 assist you in improving the performance and quality of the centralized systems for continuous monitoring of radiation and/or levels of radioactivity and ensuring a reduction in the risk to human health due to radiation.
With obedience and compliance to BS IEC 61559-1, you can enhance centralized systems’ effectiveness and efficacy and manufacture a standardized product.
BS IEC 61559-1:2009 supersedes IEC 61559-1:1996 which is withdrawn. BS IEC 61559-1: has been updated to take account of the requirements of IEC 61559-1:1996. Specifically, to meet the functional safety lifecycle requirements of IEC 61508 and/or IEC 61513 have been introduced. Additionally, functional validation and verification tests have been added as compared to the previous edition BS IEC 61559-1:1996.
