Abstract
The utility model is a kind of radioactive radiation detector, primarily of operation display panel, probe, Circuits System, power supply composition, it is characterized in that probe is Geiger counter tube, have three probes, and three probes connect with one block of pulse shaping circuit plate simultaneously, be that pulse shaping circuit plate is powered by power supply, impulse commutation circuit board connects with the single-chip microcomputer of in casing, and single-chip microcomputer connects with operation display panel.This radioactive radiation detects has the features such as volume is little, lightweight, integrated level is high, be easy to carry, also can carry out audible alarm with radioactive source power, its stable performance, easy and simple to handle, measurement result are directly by functions such as numerical monitor, it can measure β and gamma-rays, can widespread use chemical industry, medical science, chemical defence all departments radiological measuring.
Description
Technical field
The utility model is penetrating property of one radiation detector, belongs to the instrument of radiation protection safety inspection, and for finding radiocontamination, the gamma-rays dose rate in region is infected with in measurement nuclear explosion; The γ of survey crew, weapon, technical equipment and various body surface or beta activity contamination level.
Background technology
At present, in recent years, relate to nuclear incident and again and again occur, along with the development of nuclear energy and isotope technology, Application of Nuclear Technology is more and more extensive, so increase to some extent environmental radiation contact scar and radioactivity on personnel and even public's raying impact may.Therefore, be necessary that relating to nuclear site to nuclear enterpris, nuclear facilities etc. carries out radioactivity monitoring.At present, China also lacks and continuous effective can monitor the instrumentation relating to nuclear site, and a kind of radioactive radiation detector of this project development can monitor the pollution level of workplace continuously to guarantee the radiation safety of staff and environment.
Summary of the invention
The purpose of this utility model to develop that a kind of volume is little, lightweight, integrated level is high, the portable instrument for radiation protection safety inspection.
The technical solution adopted in the utility model is: a kind of radioactive radiation detector, form primarily of operation display panel, probe, power supply and casing, it is characterized in that probe is formed in parallel by three Geiger counter tubes, and three probes are simultaneously in parallel with one block of pulse shaping circuit plate, be that pulse shaping circuit plate is powered by power supply, impulse commutation circuit board connects with the single-chip microcomputer of in casing, and single-chip microcomputer connects with operation display panel.Be mainly used in radioelement monitoring and measurement in particular surroundings.
When instrument is measured, radioactive ray act on radiation probe, and three Geiger counter tube detectors in probe convert ray to electric pulse, because the pulsimeter digit rate exported is directly proportional to radiation intensity.By the negative signal provided of popping one's head in, the effect of detection circuit ray is converted to the electric pulse be directly proportional to radiation intensity, sends into pulse shaping circuit plate; The effect of pulse shaping circuit plate transmits different electrical potential information to single chip microcomputer after the electric pulse that detector exports is shaped to the electric pulse of comparison rule, the metering system of single chip microcomputer to probe is helped to make correct judgement, so that controlled by single chip microprocessor display shows corresponding data and unit.
The utility model beneficial effect is: this radioactive radiation detector volume is little, lightweight, and integrated level is high, is easy to carry, easy for operation, and stability is good, highly sensitive, is applicable to environment level and measures, and can be used for the monitoring of radioactivity field environment, of many uses.Can PLC technology be realized, flexible and convenient to use, the various radiological measuring of the various departments such as chemical industry, medical science, chemical defence can be widely applied to.
