Neutron Irradiator Systems

Our neutron irradiator provides a panoramic radiation field used primarily for instrument and dosimetry calibrations.  It is typically housed in a low scatter room and can be supplied with a full complement of accessories that include linear positioning systems, video monitoring, and safety systems.

The Hopewell Designs Model N40 series provides a 360° radiation field for calibrating radiation detection instruments and irradiating personnel dosimetry. Available with up to six radioactive sources in a wide range of activities – both neutron and gamma, the system comes complete with radiation sources, shielding, exposure position, safety interlocks, and control panel. There are four models to choose from based on source quantity and size.

  • Multiple models to choose from with capacity of 1, 2, or 6 sources
  • High precision and repeatability assure accurate calibrations with low uncertainty
  • Electronic operation or fully-automated computer control.
  • Computer control provides extensive automation to reduce errors and improve efficiency
  • Easy to use with an intuitive operator interface.
  • Inherent fail-safe design.
  • Highly reliable
  • Calibration available with traceability to NIST
  • Californium-252: 0.6 to 18.5 GBq (16.2 mCi to 500 mCi)
