The IPM9 detects radioactive emissions over the whole body, including head, hands and feet. The two-stage monitoring procedure provides consistent body sensitivity for all user sizes. Users are guided by external traffic lights, internal LEDs, a colour graphic display and (optionally) voice prompts.

Detector options: Gas Flow for maximum alpha/beta sensitivity Sealed Gas for best beta/gamma performance Scintillation for "hidden" gamma and Passive Internal Monitoring
(Standard, α & β) These Ar/CH4 detectors are extremely sensitive and have no internal dead areas. Their thin windows are protected by strong, fine hex-mesh grilles, giving maximum strength vs. sensitivity factor, with 75% transmission. Flat plateau responses to all normally encountered α or β emitters guarantee stable long-term sensitivity and maximum gamma background rejection.
These Ar/CO2 detectors are mechanically interchangeable with standard gas flow detectors. They are permanently sealed and rugged, with 5 mg/cm2 titanium windows. Their beta energy response extends down to C14 energies (157 keV). Ar/CO2 detectors are insensitive to alpha, less affected by radon, and have high gamma background rejection.
Efficiencies: (% surface emission, from large sources placed on the detector grille) :
There are two available configurations of additional gamma scintillation detectors. The passive internal monitor (PIM) option provides a lung/nasal/pharyngeal/gut gamma detector, plus lead shielding, mounted behind the body detector array. The ‘full’ gamma option provides six large area body detectors with lead shielding behind the standard body detectors, plus a gamma foot detector. On the IPM9A, two additional hand detectors are installed in the back wall.
