X-ray Irradiator Systems

Our line of X-ray calibration irradiators are designed specifically for instrument and dosimetry calibration.  They include features and accessories to facilitate calibrations and assure accurate and repeatable exposures.  We have supplied these systems to primary and secondary standards labs throughout the world.

Our self-contained X-ray irradiators are an excellent choice for R&D, cell culture irradiation, SIT, and high dose applications.  Fully shielded, it does not need a special exposure room and takes up very little lab space. 

The Model X80 X-Ray Beam Irradiator will simplify even the most tedious and time-consuming tasks associated with calibrating radiation detection instruments and personnel dosimeter badges. The control panel provides total command and monitoring of the irradiator, complete with expose and return pushbuttons, indicator lights, an emergency off pushbutton, LCD display, and a keyed power switch. The data entry keypad makes it simple to enter exposure time, filter, and attenuator selection. The optional computer-based control system offers even greater ease-of-use by automating and simplifying many steps of the calibration process. Computer controls will manage the X-ray system, calculate exposure rates, provide automatic set-up of the irradiator and provide automated calibration of the irradiator.

With its fail-safe design and a wide range of accessories, the Hopewell Designs Model X80 offers a flexible, easy to use system that will increase productivity and accuracy. Available in three configurations: the X80-160, with a range of 5 - 160 kV; the X80-225 kV - range of 5 - 225 kV; the X80-320 kV with a range of 5 - 320 kV.
