Radiation Detector Calibration Procedure
The radiation sensor contained in the FT-50 is one of two types:
• Solid State Detector (SSD)
• Scintillation Tube Detector (STD)
Solid State Detector
The Solid State Detector (SSD) uses a sensor and circuit board to
detect the strength of the gamma beam as it contacts the sensor.
The SSD does not require calibration.
Scintillation Tube Detector
The Scintillation Tube Detector (STD) uses a Scintillation Tube to
capture gamma rays and measure them. The Scintillation Tube
requires calibration approximately every three years.
