RADIATION ENVIRONMENTAL MONITORING AND PROFICIENCY TESTING

The radiation monitoring capability of CIRP has passed the national CMA certification, CNAS laboratory accreditation and DILAC accreditation, and the proficiency testing provider has been accredited by CNAS. The testing capabilities recognized of CIRP include 10 categories including water, soil and other solids (sediments, fallout, etc.), aerosols, ambient air, building materials and industrial waste, biological and organic matters, surface contamination, accumulative dose, and electromagnetic radiation, covering a total of 83 testing parameters such as γ nuclide, strontium-90, plutonium isotope, uranium isotope, tritium, carbon-14, polonium-210, iron-55, Eu-63, total alpha and total Beta, etc. CIRP is mainly responsible for radiation environment monitoring, advanced analytical technology research, monitoring related equipment development and proficiency testing. Radiation monitoring can be carried out at all stages from the pre-commissioning environmental background survey of nuclear facilities, environmental protection acceptance of the project completion, commissioning and operation to decommissioning and treatment. Possessing the ultra-sensitive measurement facilities such as small multi-nuclide accelerator mass spectrometer (AMS) and multiple tandem inductively coupled plasma mass spectrometer (ICP-QQQ), CIRP can carry out ultra-low level (as low as 10 g) analysis on radionuclide in all ambient medium samples. CIRP has developed and manufactured a variety of equipment for sample collection, pre-processing, nuclide separation, purification and monitoring. Proficiency testing, measurement calibration and inter-laboratory comparison of radionuclide monitoring in water, soil, air, biological and other environmental samples can be provided.
