An Aviation Integrated Radiation Dose Measurement System

Abstract

The invention provides an aviation comprehensive radiation dose measuring system. The aviation comprehensive radiation dose measuring system comprises a detector, a signal processing module, a signalacquisition module, an FPGA module and an aviation comprehensive radiation dose data processing module; the detector generates a charge signal response after receiving a particle effective dose signal, and outputs the charge signal response to the signal processing module; the charge signal response is amplified and converted into an analog signal capable of being sampled, and the analog signal isoutput to the signal acquisition module; and the analog signal is acquired and converted into a digital signal, the digital signal is output to the FPGA module, initialization configuration and instruction control are carried out on the detector, the signal processing module and the signal acquisition module, a fine energy spectrum of deposited energy of incident particles and a radiation doses of comprehensively detected particles are calculated according to the acquired digital signal, components and neutrons of the incident particles are identified, and an aviation comprehensive radiationdose data display and storage module is used for displaying and storing data uploaded by the FPGA module.

Description

technical field [0001] The invention belongs to the field of aviation flight environmental radiation measurement, and in particular relates to an aviation comprehensive radiation dose measurement system. Background technique [0002] The radiation particles in the aviation flight environment mainly come from various secondary particles produced by galactic cosmic rays in the atmosphere and aircraft. The aviation radiation dose is mainly contributed by high-quality factor radiation events. Simply measuring the absorbed dose will seriously underestimate the aviation radiation. Therefore, it is also necessary to measure the quality factor of each radiation event, and at the same time ensure that the measurement covers various radiation elements in the aviation irradiation field, especially neutrons are the key monitoring content of aviation particle irradiation. [0003] At present, the energy spectrum response range of the commonly used environmental radiation dose monitoring ...
