General Description
The Nanosecond X-Ray Detector will accurately measure the integrated total dose from pulsed x-ray machines over a wide range of pulse widths and repetition rates. This monitor also measures low energies and short pulses that other survey meters ignore to the detriment of worker health. Digital readout: 6 digit-rate, 8 digits integrate dose rate and total dose read out, flat response. Sealed air ion chamber sees axially below 5 KeV gamma or x-ray. Detects beta, gamma, x-ray, positrons with a fast response and wide range. Especially useful in Non-Destructive Testing or other Industrial or Medical applications where pulsed x-rays are used. End Users: US Military, Hospitals, Aircraft and Other Manufacturing.
Technical Description
The Nanosecond X-Ray Detector consists of a 2” diameter air ion chamber coupled to a stable solid state MOSFET input electrometer with built in A to D converter to read out directly in mR/h or total mR. Rate range is 0.01 R/h to 100 R/h in a single range. Dose range is 0.001R - 100R in a single range. Other Ranges are also available. Options include: Other Rate or Integrated Ranges; Other Readout Units such as Si units: Sv and Sv/h.
