What is ISO 2889 about?
ISO 2889 discusses airborne radioactive materials. The radioactive materials discussed in ISO 2889 are found in the stacks and ducts of nuclear facilities. ISO 2889 describes the sampling of these airborne radioactive materials from the stacks and ducts of nuclear facilities. ISO 2889 sets forth performance-based criteria and recommendations for the design and use of systems for the sampling of these airborne radioactive materials in the effluent air from the ducts and stacks of nuclear facilities.
ISO 2889 provides requirements and recommendations that aim at sampling that is conducted for regulatory compliance and system control.
Note: ISO 2889 does not address outdoor air sampling, radon measurements, or the surveillance of airborne radioactive substances in the workplace of nuclear facilities.
Who is ISO 2889 for?
ISO 2889 on sampling airborne radioactive materials is useful for:
- Nuclear facilities
- Government bodies
- Health and safety inspectors
- Quality control personnel
Why should you use ISO 2889?
Radioactive airborne particles are harmful to your health. That is why you need to monitor the emissions from stacks and ducts of nuclear facilities. For this a sampling method has been described in ISO 2889. The goal of achieving an unbiased, representative sample is best accomplished where samples are extracted from airstreams in which potential airborne contaminants are well mixed in the airstream. ISO 2889 performance criteria and recommendations assist you in obtaining valid measurements of the concentration of airborne radioactive materials in ducts or stacks.
ISO 2889 focuses on monitoring the activity concentrations and activity releases of radioactive substances in the air in stacks and ducts. Other situations for monitoring the activity concentrations and activity releases of radioactive substances in the air (environmental or workplace monitoring) are being addressed in subsequent standards.
ISO 2889 provides performance-based criteria for the use of air-sampling equipment, including probes, transport lines, sample collectors, sample monitoring instruments and gas flow measuring methods. ISO 2889 also provides information covering sampling programme objectives, quality assurance, development of air monitoring control action levels, system optimization and system performance verification.
What’s changed since the last update?
BS ISO 2889:2021 cancels and replaces ISO 2889:2010
The main changes are:
- Clarification of the circumstances where numerical modelling may be used to perform or assist with meeting the qualifications for sample extraction locations
- Clarification of passages allowing the use of alternate aerosol particle sizes for testing to meet various performance criteria described
- Changes for the discussion of standard uncertainty about setting action levels
