Radiation Counting System with Alpha probe for measurement of gross alpha activity/contamination [ TYPE : RC 605A ]
Technical Data
Radiation Counting system, Type RC605A manufactured by NUCLEONIX is a versatile state of art integral counting system designed around eight bit microcontroller chip for using with a variety of detector probes such as Alpha / Beta / Gamma scintillator detector probe or End window G.M detector probe.
RC605A is Highly recommended for gross alpha activity / contamination mesurement (in water & other environmental samples) with alpha probe AP165 connected, for Radio anaytical labs, Health physic counting labs and Environmental survey labs at Nuclear power stations.
Radiation Counting System essentially has a processor card and other electronic circuits to generate continuously variable HV upto 1500V to be applied to scintillation detector Probes (α, β, γ) or End window G.M.Tube, amplify the detector output and convert them to digital pulses for counting and displaying the recorded counts for a preset time.
Microcontroller design facilitates programmability for background, standard and sample counting. The data can be downloaded into PC or printed directly onto a printer.
System facilitates counting of samples either on planchets or filter paper.
This system will find applications for counting of air activity, wipe, environmental, geological and other samples for both beta , gamma and alpha activity. Activity report is generated for unit volume of sample.
