Abstract

The invention discloses a radioactive aerosol sampling device, which is suitable to be fixed on an aircraft. The radioactive aerosol sampling device comprises a sampling tube, a sampling assembly, a detecting assembly, a processor assembly and a power supply, wherein a sampling cavity is arranged in the sampling tube; the sampling assembly is used for acquiring aerosol in air flowing through the sampling cavity; the detecting assembly comprises a temperature and humidity sensor, an air pressure sensor, a flow sensor and a GPS (global position system) antenna; the processor assembly is connected with the detecting assembly, and used for converting analog signals into digital signals and storing the digital signals; and the power supply is respectively connected with the processor assembly and the detecting assembly, and used for supplying power to the processor assembly and the detecting assembly. The radioactive aerosol sampling device disclosed by the embodiment of the invention has the advantages of small volume, short sampling time, wide sampling area, unrestricted sampling positions, large acquisition quantity, comprehensive data acquisition, and capability of improving the security of workers in accident areas, and the like.

Description

technical field [0001] The invention relates to the field of radioactive atmospheric environment monitoring, in particular to a radioactive aerosol sampling device. Background technique [0002] Radioactive aerosol monitoring is an important part of atmospheric environmental protection. It is of great significance for the timely detection of abnormal radioactive leakage in nuclear industry production and the implementation of atmospheric environmental pollution control. However, the current radioactive environmental monitoring has the following problems: after an accident, the accident area is highly radioactive, and it is not suitable for staff to enter to carry out ground sampling; the distribution of radioactive aerosols is large, and the cost of personnel evacuation is high. Therefore, how to carry out high-efficiency aerosol sampling in a large area under the premise of ensuring the safety of staff has become a problem in emergency monitoring of radioactive environments...
