Detailed Product Description
Radioactive surface contamination measuring instrument HRDmu-I
Both α/β surface measurement and environment contamination γ measurement characteristics
can store 100, 000 bunches of data, and has data communication function.
it is easy to read the numerical value and simulation barcode show.
it is light and easy to use, and high reliability
HRDmu-I adopts semiconductor detector. It is suitable for low level α β surface radiation contamination detection and environment X γ radiation monitoring. Have good detection efficiency high reliability and convenient operation characteristics. The one probe can distinguish measure alpha and beta with delicate design, and also can be used for environment X γ radiation dose level measurement.
The instrument adopts single-chip microcomputer control. Can record and store the measure data continuously. It can be used in environmental radiological monitoring; nuclear medicine; nuclear power station; nuclear fuel production, reserves and transport and so on.
