description The invention relates to a portable calibrating device for alpha and beta surface contamination instruments. The portable calibrating device comprises a fixing frame base and a probe fixing frame, thefixing frame base is provided with a plane source groove and an edge upper fixing stand column. The probe fixing frame is provided with a measuring window matched with the plane source groove; and the probe fixing frame is sleeved on a fixed upright post on the edge of the fixed base through a through hole, so that the distance between the probe detection window of the surface pollution instrument and the surface of the plane source conforms to a preset value. The calibrating device is simple to operate and high in precision, can calibrate/calibrate alpha and beta surface contamination instruments of different types of probes, and is convenient to carry for outdoor calibration. 本发明涉及一种α、β表面污染仪便携式检定装置，包括固定架底座和探头固定架；所述固定架底座上设置有平面源槽和边沿上固定立柱；所述探头固定架上设置有与所述平面源槽配合的测量窗口；所述探头固定架通过通孔套装于所述固定底座边沿上的固定立柱上，以使所述表面污染仪探头探测窗与所述平面源
