Description
Technical field
The present invention is used in the field of radiation detection of needing, be related to it is a kind of can emission-type at a distance can distribution measuring amount of radiation
Detector.
Background technique
According to data statistics, occurred serious nuclear leakage accident has 11 altogether from nineteen fifty-seven to the whole world 2011, wherein
People, which is influenced, by nuclear radiation reaches hundreds of thousands of them.Furthermore it works in nuclear power station, rare earth mining site, the hospital containing X-ray machine and relevant
Personnel's moment is by the threat from radiation under the environment such as scientific experiment.Ionising radiation is to cell to its essence of the damage of body
Deactivation, when the cell being inactivated reaches certain amount, the damage of body cell will lead to human organ tissue generation
Disease may finally cause human body dead.Radiation may also lead to genetic mutation, when the DNA in reproduction cell by
When damage, offspring inherits the gene that parent changes, and leads to defective offspring.The only some region of spoke of accurately measure
The amount of penetrating and with reference to this measurement data, personnel just can know that whether the amount of radiation in the region exceeds human body and can bear
Normal level, then make corresponding measure.
But present nuclear radiation detector is all hand-held or human body is needed to be carried along into region to be measured, such survey crew
Protective clothes entrance must be dressed, even if related personnel in this way is also to risk the risk radiated, while measuring radiation signal
It is certain point in space, can not accurately represents the radiated signal strength in entire space.It is partly led so that one kind is high-resolution
(patent name " a kind of high-resolution semiconductor nuclear radiation detector ", Chinese Patent Application No. is for bulk detector
CN200710075334.5), the carrier generated in the semiconductors is radiated, is collected under reverse biased electric field, by what is generated
Electric impulse signal measures nuclear radiation, with high-purity N type silicon wafer does semiconductor material.High-purity silicon detector has higher energy resolution
Rate, it is high-efficient to γ radiation detection, it can save, be widely used at room temperature.The materials such as GaAs, cadmium telluride, mercuric iodixde also have
Using.Such as the rolometer of Germany Ke Lei research and development is all to need to bring instrument into environment to be measured, measures the signal of single-point.
Personnel had both been increased in this way by the risk of radiation irradiation, while also being obtained area radiation signal to be measured and being inaccurate.
Summary of the invention
The purpose of the invention is to provide it is a kind of can emission-type at a distance can distribution measuring amount of radiation detector, can be real
Some region of single-point or distributed radiation intensity are now remotely measured, is to be sent fibre-optical probe to area to be measured by emitter
Domain is gone to detect the device of the amount of radiation in the area.
The object of the present invention is achieved like this: including emitter, carrier that emitter transmitting terminal is arranged in, setting
Winding roll, detection case in emitter lower end, the carrier include carrier tip and carrier inner core, and in-core is set in the carrier
It is equipped with distribution type fiber-optic, the distribution type fiber-optic includes restrictive coating, the becket that restrictive coating both ends are arranged in, is arranged in restrictive coating
Interior optical fiber, the optical fiber at least there are three and length it is different, be provided with light-sensitive material on each optical fiber, twined on the winding roll
Be wound with cable, the connection of survey optical module in one end and detection case of cable, the other end be wrapped on restrictive coating and with distributed light
Fibre connects, and the capture card connecting with survey optical module is additionally provided in the detection case.
The invention also includes structure features some in this way:
1. being provided with display box and operation interface on the detection case.
2. the emitter is gun body or bow and crossbow.
Compared with prior art, the beneficial effects of the present invention are: it is to be measured in order to effectively avoid survey crew from being directly entered
In environment, and obtain more accurate radiation signal, the present invention provide it is a kind of can emission-type at a distance can distribution measuring amount of radiation
Distribution type fiber-optic can be popped one's head in and be emitted to region to be measured, and will detect the device of the radiation ray in the region by detector.Dividing
In cloth optical fiber, optical fiber can be unique hierarchic structure and place, and be also possible to other different distribution modes, thus both can be with
The radiation value for detecting target area single-point, also can detecte the radiation value of the difference in target area.Fibre-optical probe will acquire
To signal detector is transmitted to by optical fiber.Probe need to be only emitted to be measured by survey crew by using such device
Region with personnel without being entered.Compared to traditional measuring instrument device, this design can detect due to landform that personnel can not
Into the nuclear radiation in area, the use scope of nuclear radiation detection device is expanded, and collects three-dimensional spoke using distribution type fiber-optic
Signal is penetrated, personnel and substance are effectively saved, reduces the cost of measurement.
Radiation detector of the invention has many advantages, such as not only there is common inspection compared to the detector on current market
Remote target area can also be detected in the function of the region detection amount of radiation where instrument by surveying instrument, and
And its unique distribution type fiber-optic probe can measure the three-dimensional distribution of target area amount of radiation, this is radiation inspection currently on the market
Survey what instrument was not accomplished.The probe emitter of radiation detector of the invention can be using gun body or bow and crossbow as platform, should
Emitter is similar to line throwing gun.
The hierarchic structure of insertion carrier distribution type fiber-optic can make signal collected by every optical fiber come from space
In three-dimensional coordinate difference.Excitation of the atom of sensitive material in fibre-optical probe by radiation energy, electronics is from low-lying level
High level is transitted to, so that atom is in excitation state, excited atom is spontaneous to be returned to ground state and issued energy in the form of fluorescence
Amount, the fluorescence signal intensity that the radiation excitation of varying strength goes out are also different.Fluorescence travels to detector in a fiber.It is distributed
Optical fiber with detector main body is connected with cable, and cable is wrapped in optical fiber and intensity is sufficiently large, and optical fiber can be protected to be emitted to
It is not damaged during target area.Cable is mainly wrapped in cable reel, and reel is rotation during the launch process, this
Sample can release sufficiently long cable.Cable passes through reel central axis and connects with the host containing detector.Containing multiple in host
Detector, input terminal are that illuminant module connects optical fiber, and output end output electric signal is shown after treatment can be realized pair
The detection of amount of radiation.
It is detected since current radiation detector requires artificial region to be measured of bringing into, and is not necessarily to using the present apparatus
Survey crew wears any protective equipment and can measure.It can be with the workspace where testing staff under non-emission state
Whether domain amount of radiation is safe, and then personnel carry out relevant operation outside region, so that it may by the collected spoke of distribution type fiber-optic
Penetrating signal can be shown on instrument.Different flat pads can be additionally carried according to different demands, utilize the bullet of bow and crossbow
The gunpowder motive force of power, the compressed gas motive force of air gun and rifle, so low manufacture cost, and it innovates detection method significantly
Cost needed for reducing a radiation detection.
