CM7/CM9 CONTAMINATION MONITORS

Wall-mounted units for use at the boundaries of controlled areas and in subchangerooms. Also ideal for smaller radiation laboratories.

Preferred over portable instruments when the advantages of greater ease of reading, automatic background subtraction, bright displays, separate indication of alpha and beta, and unambiguous alarm indications are considered of particular importance.

· CM7 uses a 100 cm^2 gas flow detector.

· CM9 uses NE Scintillation Probes (see p14).

· Easy monitoring of clothing, tools etc.

· CM7 works with HFM7 for faster staff throughput.

IBEX CONTAMINATION MONITOR

Unique detector cum wall-mounted display offering a greater efficiency than xenon probes for iodine, betas and X-rays above 20keV. It operates with an usealed thin window which is both reliable and more transparent to low energy betas than a xenon probe. (Windows can be economically replaced on-site.)

· Dual measuring channels

· Ideal for medical/pharmaceutical applications.

· Uses CM9 with hand/clothing capabilities.

SHM1 SINGLE HAND MONITOR

Approved for use in alpha plants, where glove damage could cause a hazardous release from the glove box. Utilises a large air-proportional counter to measure the full face of the hand with beter sensitivity and control than might be achieved by a hand held probe.

The rugged detector is insensitive to light, needs to counting gas and its construction gives both remarkable uniformity and ease of maintenance.

· Easy, digital set-up and calibration.

· Incorporates hand sensor for easy operation.

HM7/HM9 HAND MONITORS

Robust, dependable instruments with the same general qualities as the HFM7, offering precise,sensitive performance , combined with fast and easy operation. The HM7 utilises four gas flow detectors whilst the HM9 employs scintillation. Both measure alpha and beta simultaneously.

Detectors are mounted vertically to avoid build-up of foreign matter on the Windows.

HFM7 HAND AND FOOT MONITOR

A fast, highly sensitive instrument detecting alpha and beta on each hand foot. Spring-loaded hand counters provide optimum sensitivity, while special sensors, easy operating procedure and clear displays ensure correct operation.

· Precise settings, using digital controls.

· Advanced data processing.

· Self monitoring to maintain peak operating performance.

SPM900 PORTAL MONITORS

A new improved range of body monitors to detect small quantities of gamma radiation, either from typical reactor contaminants or from Special Nuclear Materials (according to software pack). Incorporates plastic scintillation detectors built into the two pillars, the foot ramp and lintel—also an advanced electronic controller.

· Includes 12 hr battery back-up.

· Includes 3/8 sinch (1cm) lead shielding.

WTM1 WALK THROUGH MONITOR

Sensitive portal monitor for the earliest detection of betas within controlled zones. The unobutrsive detection system first measures the peak count response and then averages adjacent counts to improve sensitivity – whilst the occupant is stil walking through.

· Occupancy sensor triggers measurement

· Location of contamination displayed
