Abstract

The invention relates to a radial measuring instrument for measuring radial dosage. The radial measuring instrument for measuring radial dosage comprises a photoelectric sensor, a first amplifying circuit, an integral circuit, a second amplifying circuit, a analog to digital to digital (A / D) converter, a single chip and a displaying circuit. The first amplifying circuit is composed of a first differential amplification circuit, a first calibration voltage circuit and a first inverse proportion amplifying circuit. The second amplifying circuit is composed of a second differential amplification circuit, a second calibration voltage circuit and a second inverse proportion amplifying circuit. The radial measuring instrument for measuring the radial dosage is characterized by further comprising a first alarm circuit and a second alarm circuit. The input end of the first alarm circuit is connected with the output end of the first inverse proportion amplifying circuit. The input end of the second alarm circuit is connected with the output end of the second inverse proportion amplifying circuit. The radial measuring instrument for measuring the radial dosage has the advantages that manpower and material resources of making radial exposure charts are reduced and work efficiency is improved.

Description

technical field [0001] The invention relates to a radiation measuring instrument for measuring radiation dose, which is especially suitable for making exposure curves and controlling the cumulative dose of radiation in the detection of industrial X-rays. Background technique [0002] At present, the detection of industrial x-ray exposure curves is mostly made by ray film exposure, and the blackness of the film is measured. On the one hand, a large amount of film is used to do this. , time-consuming and labor-intensive. Therefore, a sheet-shaped radiation dosimeter capable of measuring the cumulative dose of radiation is designed for making radiation detection exposure curves or for detecting radiation doses during exposure. Contents of the invention [0003] Aiming at the above problems, the present invention provides a sheet-shaped radiation measuring instrument for accurately measuring radiation dose. [0004] The technical solution adopted by the present invention to ...
