Radiation Detector

The D-Pace radiation detector is a compact, simple, and reliable gamma radiation detector consisting of a large area photodiode and a dual op-amp circuit sensitive only to radiation sources immediately in front of the photodiode. The detector provides an analog output voltage signal suitable for processing in a computer data acquisition system, or for direct display on a dc voltmeter.  The unit requires only + and – 15 VDC for operation at milliamp currents.

Features

  • Compact (58mm length by 19mm diameter), while still maintaining adequate sensitivity and durability.
  • Inexpensive.
  • Low power consumption.
  • Long life.

Performance

  • There is a linear response to radiation as shown in the plot in fig. 1.
  • Output is temperature dependent so a stable temperature is advisable

Fig. 1: The dependence of the output voltage on the amount of activity was examined by exposing the radiation detector to several fixed 137Cs calibration sources.

Specifications

  • Signal returned as 0 to 10 volts analog
  • Size for mounting: 58mm length by 19mm diameter
  • Comes with straight plug 4 pin half moon 7A brass lemo connector.

Applications

  • Processing systems such as radiochemical or radiopharmaceutical synthesis modules.
