Gamma scintillation probe with stand * [ Type No. : GSP1]
Technical Data
This essentially consists of a 2″ x 2″ NaI Integral detector, with PMT / HV bleeder wired & enclosed in a cylindrical shell with appropriate connector brought out for applying HV bias to PMT & also for taking signal output to the Radiation Counting System.
This probe with NaI crystal facing downwards is placed in a sample holder having slotted arrangement for placing sample tray. Samples either filter paper deposited air activity sample or in a SS planchet can be kept for gross gamma activity counting. This Radiation counting system cannot be used for selection of a specific energy band.
For applications requiring counting for a specific energy band one has to opt for Gamma ray spectrometer.
