| Zusammenfassung: | 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. |
