PERSONAL DOSE MONITORING

Personal Dose Monitoring of External Exposure

CIRP supplies a complete set of personal dose monitoring solutions of external exposure for nuclear industry and nuclear technology companies, including monitoring management system, active/passive external exposure personal dose monitoring equipment and services, etc.

In response to the needs of personal dose monitoring of internal exposure in normal or emergency scenarios, CIRP provides internal exposure in-vivo measurement, dose assessment systems and monitoring services. In addition, CIRP is able to conduct calibration and performance testing on internal exposure in-vivo measuring systems with human phantom. In terms of the analysis of radionuclides such as uranium, plutonium and tritium, corresponding testing capabilities have obtained the national CMA certification and CNAS laboratory accreditation.

CIRP is capable of a variety of radiation monitoring, including dose equivalent rate measurement of different rays, surface contamination monitoring, continuous monitoring of radioactive effluent, environmental cumulative dose monitoring, and radiation source term investigation.

Environment, Workplace and Effluent Monitoring

Investigation of Radiation Source Term and Weakly-Penetrating Radiation

CIRP performs on-site non-destructive measurement of radiation source terms deposited inside nuclear facilities, equipment and pipelines to obtain information such as nuclide type, activity, dose rate contribution, and γ radiation field dose rate level, in an effort to provide data for source term control and protection. CIRP investigates and measures the spectral characteristics, directional dose equivalent rate and personal dose equivalent (eye lens, skin, acra) of weakly penetrating radiation, to evaluate the performance of protective equipment, systematically understand the level of weakly penetrating radiation and its hazard, so as to improve on-site radiation protection management.

Digital Radiation Protection Management System

CIRP, based on the industrial digital technology, transforms and develops digital radiation monitor to collect various radiation monitoring data. In the meantime, CIRP is able to achieve more comprehensive information than conventional radiation protection by utilizing integrated storage and analysis of time and space information, thereby laying the foundation for intelligent data analysis and prediction to promote the intelligentization of radiation protection. By providing three-dimensional radiation field measurement, calculation and visualization system development, customized intelligent radiation monitoring equipment transformation and construction of digital radiation protection management system, CIRP is able to improve the ALARA management of nuclear facilities.

NUCLEAR INSTRUMENT VERIFICATION, CALIBRATION, AND TESTING SERVICES

The Radioactivity Measurement Laboratory of CIRP currently has 14 sets of standard measuring systems, which are divided into three categories of dose, activity and neutron. These systems can be applied to carry out the verification, calibration and testing of X, γ, α, β and neutron radiation monitoring instruments. Online calibrating services can be provided for some radiation monitoring instruments, and high or low-temperature environmental adaptability testing can be conducted under conditions with radiation fields.
