Radioactive aerosol automatic monitoring instrument

Abstract

The invention relates to the field of aerosol measurement, in particular to a full-automatic monitoring instrument for radioactive aerosol. The measurement instrument integrates a sampling device, a sample preparation device, a measurement device and a control unit; the sampling device comprises a filter membrane, a filter membrane storage device, a mechanical transmission mechanism, an intelligent air pump, an aerosol sampling head and a sampling air chamber; the control device is used for automatically controlling sampling, sample preparation and measurement; the sample measurement device is used for measuring a sample; the aerosol sample is quickly, continuously and fully-automatically collected in a radiative environment, the sample is automatically prepared, the gamma dosage rate is automatically measured, and data is automatically acquired, analyzed, stored, processed and transmitted to a database appointed by a user; natural nuclide, medical nuclide, industrial nuclide, artificial nuclide and the like are detected, and the problems of manual sampling, sample preparation, measurement and collection required for a long term are solved. The measurement instrument is high in intelligent degree and simple and convenient to operate, and can save a large amount of manpower and material resources, thereby having a great promotional value.

Description

Technical field [0001] The invention relates to the field of aerosol measurement, in particular to a radioactive aerosol automatic monitoring instrument. Background technique [0002] Radiation environmental monitoring is an important part of environmental monitoring and the basis of radiation environmental management. The purpose of radiation environment monitoring is to provide basic data for estimating and controlling the radiation exposure of the public and workers. Radiation environment monitoring plays an irreplaceable role in the safe use of radioactive sources, searching for lost radioactive sources, and determining the extent and scope of damage and pollution of radioactive sources. [0003] Commonly used radiation monitoring instruments are mainly composed of detectors and secondary electronic instruments, mainly gamma radiation monitors; alpha and beta surface pollution monitors; neutron monitors; pyro-dosimeters and measuring instruments, among which gamma radiation is...

AI Technical Summary

Problems solved by technology

The equipment is simple in structure and easy to operate, but because the equipment does not have automatic sampling, sample preparation and measurement devices, it cannot automatically perform continuous sampling and measurement. The sampler needs manual replacement of the filter membrane, and real-time monitoring requires a lot of manpower and material resources.

In addition, the device can only realize the sampling operation, and cannot specifically measure the radiation level in the sample, and further measurement processing is required manually. The degree of integration is too low, and the value of popularization and application is too low
