Fig. 2 is the schematic diagram of measuring instrument of the present invention.
Each label is respectively as follows: 1, touch display screen, 2, hand detector, 3, window of swiping the card, 4, casing, 5, foot in figure
Detector.
Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Trick surface α β contamination meter as shown in Figure 1: including touch display screen 1, hand detector 2, window of swiping the card
3, casing 4, foot's detector 5.Hand/foot's detector by 4 pieces of large-area flicker detectors and protective net, be protected from light aluminium film, dodge
The compositions such as bright crystal, signal collection processing unit.It is fixed in metal detector shell, flashes as shown in Fig. 2, it forms device
Crystal faces outwardly, and covers crystal using aluminium film, achievees the purpose that be protected from light.α and (or) β ray penetrates aluminium film and beats in scintillation crystal
On, lead to crystallo-luminescence, optical signal is collected to after photomultiplier tube by light guide and is converted to identifiable electric signal, then is passed through
α the and (or) β ray signal detected is screened and is converted to digital data transmission to measuring host by signal processing circuit.
The surrounding of the host of measuring instrument is provided with casing, includes communication module, signal processing circuit, electricity in measuring instrument host
Source module, data communication module, detector connect power supply and communication module, communication module connection signal processing circuit, for pair
α the and (or) β ray signal detected is screened, and signal processing circuit connects data communication module, and obtained result is passed
It transports in touch display screen.
Two hand detectors and Liang Ge foot detector are fixed by casing, and signal cable is connected internally to survey from casing
Host is measured, measurement host includes communication module, power module and touch display screen.Communication module and power module and 4 detections
Device is connected, and provides working power and obtains measurement data.
As shown in Figure 1, the touch display screen is man-machine interactive component, to show measurement data and setting parameter et al.
