General Description
The Radiation Control Monitor can be tailored to at least 50 configurations meeting a variety of objectives in monitoring radioactivity including:
exit/doorway monitor
package/mail monitor
vehicle monitor
laundry monitor
To maintain control of radioactive materials it is absolutely essential to control and to know when and where radioactivity is entering or leaving the area where it is used. The Radiation Control Monitor consists of:
Multi-channel systems
Highly sensitive (50 detector models)
Alarms with detection of radiation
Relay control can lock doors and trigger a Siren or autodialer or e-mail
Two of the many radiation control monitor systems are high sensitivity monitors which are easily placed at entrance and exits and other strategic locations.
Technical Description
The Radiation Control Monitor includes:
Engineering Units: User can input correct conversion factor and change to any units.
Controls: Front Panel: On-Off, Alarm-mute, Rate, Integrate, Reset.
Recessed or Internal: Discriminator level, high voltage.
Detectors: Any GM or alpha, beta, gamma or neutron scintillator. Over 50 probes and sample detectors to choose from.
Input Sensitivity: Adjustable from less than 1 millivolt to 100 millivolt

Tier Selection
The in-depth, 99 question survey used to evaluate all detectors was weighted and scored by subject matter experts. The question weighting was specific to each of the four scenarios. Once all the detectors were scored, they were placed into tiers based on how they compared to other detectors of the same type (bio, chem or rad) and scenario (field, mobile, diagnostic, and analytical).

Scoring Analysis
System scores are compared across the four scenarios and ranked from highest to lowest.
Impact Chart
The Impact Chart is a spider graph representing specific categories and designed to give the reader a visual depiction of how a particular system is expected to operate across the four different scenarios. The score for each of the seven categories is presented as the percentage of the total possible score. Higher category scores extend the spokes of a graphic toward the outer edge of the chart. The area graphed for each of the four scenarios relates to how well the system performed in that scenario. Graphics for each of the four scenarios are super-imposed for ease of comparison.
