该仪器是核测试领域中测量干样品αβ的2π发射率的仪表,它由2π零屏栅高效αβ探测器(发明专利:ZL92 1 11938.0)与反符合探测器组成的箱式探头,并同反符合技术合理结合,组成整机。其特点是:在探测器内能稳定测量面导电性差(面电阻<10~(13)Ω)的干样品的αβ发射率;既能直接测定出αβ共存发射样的β发射率,又能同时鉴别出α和β发射率,它是放射计量、辐射防护和环境保护中的一种αβ辐射测量的优质手段。该仪器可广泛用于科研、矿料、建材、塑料、药材、海陆生物等样品的αβ低辐射水平测量。
This instrument is a 2π emissivity measuring instrument for measuring αβ in dry samples in the field of nuclear testing. It is composed of a 2π zero screen grid-efficient αβ detector (invention patent: ZL92 1 11938.0) and an anti-coincidence detector, In line with technical and reasonable combination of the whole machine. The invention is characterized in that: the αβ emissivity of a dry sample with poor conductivity (surface resistance <10 ~ (13) Ω) can be stably measured in the detector; the β emissivity of the αβ coexisting emission sample can be directly measured, Alpha and beta emissivity are identified and are excellent tools for alpha-beta radiation measurement in radiometric, radiological and environmental protection. The instrument can be widely used in scientific research, mineral materials, building materials, plastics, herbs, sea and land samples and other samples of αβ low level of radiation measurements.
