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.
ISO 2889 on sampling airborne radioactive materials is useful for:
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.
