STATE OF ART INSTRUMENTATION FROM AN INNOVATIVE COMPANY
BETA REFERENCE STANDARD SET [ Type : BS 280 ]  
Technical Data
BS-280

BS 280 consists of a set of FIVE uncalibrated Beta reference sources evaporated and sealed on 25mm dia x 5mm plastic disc covering FIVE photopeak energies with activity in the range of 0.1 to 0.4 micro curie. A reference chart for this is given below. These radioactive sources offered are from BRIT. This BS280 serves as an uncalibrated reference source set, for RC605A with Beta probe --- wide end window GM. Detector and also for low background Beta counting system.The accuracy of these sources is in the range of +/-10%. All these disc sources are enclosed in a neatly polished wooden box .
