BDPA-07 detecting unit of alpha radiation is used both as a part of the MKS-07 POSHUK search dosimeter radiometer and within automated systems of radiation monitoring of ECOTEST trademark developed by our company. BDPA-07 alpha radiation detector is supplied to the customers after metrological testing.
Detecting unit is intended for search for alpha radiation sources and measurement of surface alpha-particles flux density. Attach BDPA-07 alpha radiation detector to the telescopic tube and this will help you find alpha radiation sources promptly when inspecting large objects. Counters in corona discharge mode are used in BDPA-07. The unit can easily operate in wide temperate range – from minus 25 up to plus 55 degrees Celsius. Weight of the detecting unit is 0,65 kg.
