[ 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. The system is suitable for counting Alpha, Beta and Gamma sample counting with appropriate detector probes. This system essentially works as a Beta sample counting system with any one of the probes GM125/SBP-2 connected to it.
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 ( a , b , g ) 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.

Applications : This system will find applications for counting of air activity, wipe, environmental samples, including air, water (river, lake, pond, ground & sea waters), soil, vegetation & biological sample.
System can be used by testing labs, Environmental survey labs at Nuclear Plants, in normal or in a Nuclear disaster scenario.
