Abstract
The utility model discloses an alpha-ray and beta-ray measurer, which relates to the field of alpha-ray and beta-ray measuring and comprises a lead chamber, a photomultiplier, a main detector and a reversely-combined detector photomultiplier. The photomultiplier is connected with the main detector, the other end of the main detector is connected with the reversely-combined detector photomultiplier, and the reversely-combined detector photomultiplier is perpendicular to the photomultiplier. The alpha-ray and beta-ray measurer overcomes the defects of high cost, large weight, low instrument technical indexes and the like in the prior art, and is simple in structure, low in cost, light in weight and high in technical indexes.
Description
Technical field
The utility model relates to α, beta-ray measurement field, relates to a kind of α, beta-ray measurement appearance in particular.
Background technology
Both at home and abroad with scintigraphic low background α, beta-ray measurement appearance product, the photomultiplier of the photomultiplier of main detector and anticoincidence detector is in coaxial direction at present, and this kind cost of products height and weight are big, and the technical indicator of instrument is on the low side.
The utility model content
Deficiency such as high for the cost that overcomes like product in the prior art, that weight big, the technical device index is on the low side; The utility model provides a kind of novel α, beta-ray measurement appearance product; It comprises vitriol chamber, photomultiplier, main detector and closes the detector photomultiplier repeatedly; Said photomultiplier is connected with main detector, the said main detector other end with close the detector photomultiplier repeatedly and be connected, saidly close repeatedly that the detector photomultiplier is vertical with photomultiplier to be provided with;
An embodiment according to the utility model is said, and said photomultiplier and main detector all are arranged in the vitriol chamber, and said detector photomultiplier one end that closes repeatedly stretches out vitriol chamber.
Compared with prior art, the beneficial effect that the described signal of the utility model is read bar is, it is low, simple in structure to have a background, characteristics such as easy to operate; The computing machine that can join disposable type, the adjusting of the data aggregation of system and processing, high pressure, the control of measuring process are accomplished by computing machine; Can be used for radiation protection, environmental sample, practical water, medical and health; Agricultural sciences, nuclear power station, reactor; Isotope is produced, and the measurement of α, Beta-ray total activity in the fields such as address exploration also can be used for the on-the-spot contaminant water of nuclear battlefield center nuclear bag; Air, grain, the measurement of the total specific radioactivity in the soil.Highly reduced and have a novelty, the vitriol chamber general assembly (TW) reduces, and instrument cost reduces, and has improved the technical indicator of instrument.。
Description of drawings
Fig. 1 is the structural representation of the described α of the utility model, beta-ray measurement appearance.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the structural representation of the utility model.As shown in Figure 1; The utility model comprises vitriol chamber 1, photomultiplier 2, main detector 3 and closes detector photomultiplier 4 repeatedly; Said photomultiplier is connected with main detector, said main detector 3 other ends with close detector photomultiplier 4 repeatedly and be connected, saidly close detector photomultiplier 4 and photomultiplier 2 vertical settings repeatedly; Said photomultiplier (2) and main detector 3 all are arranged in the vitriol chamber 1, and said detector photomultiplier 4 one ends that close repeatedly stretch out vitriol chamber 1.
The computing machine that can join disposable type, the adjusting of the data aggregation of system and processing, high pressure, the control of measuring process are accomplished by computing machine; Can be used for radiation protection, environmental sample, practical water, medical and health; Agricultural sciences, nuclear power station, reactor; Isotope is produced, and the measurement of the total activity of α, β in the fields such as address exploration also can be used for the on-the-spot contaminant water of nuclear battlefield center nuclear bag; Air, grain, the measurement of the total specific radioactivity in the soil.Highly reduced and have a novelty, the vitriol chamber general assembly (TW) reduces, and instrument cost reduces, and has improved the technical indicator of instrument.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
Claims (2)
