Hand-Foot Contamination MonitorAlpha · Beta · Gamma Frisker for Hot-Lab Exit Control
Gas-less scintillation hand-foot-clothing contamination monitor. Two hand detectors plus two foot detectors with an optional detachable hand probe for frisking. Two-step hand measurement (palms then backs), dynamic-background algorithms, multi-language voice prompts and Ethernet LAN connectivity as standard. The exit-point safety device that gates every hot-lab and theranostic-centre staff egress.
Key Features
- Measurement of surface contamination by alpha, beta and gamma emitting radionuclides on hands, feet and clothing
- Gas-less smart scintillation detectors — no P-10 / methane gas supply, no flow regulation, no consumable changeout
- Optimised four-detector layout (two hand, two foot) with optional detachable hand detector for frisking arms / clothing
- Two-step measurement of hands — palms and backs separately — eliminating the contamination shadow that a single-pass measurement misses
- Dynamic processing algorithms — measurement time adapts to instantaneous background, shortest practical reading for low-background sites

Applications
Contamination control at every controlled-area exit
Nuclear-medicine hot-lab exit
Every staff egress from the radiopharmacy passes through the frisker. Two-step hand measurement catches contamination on the back of the hand that a single-pass frisker misses — the dominant late-shift egress failure mode.
Cyclotron / PET centre exit
F-18 / Ga-68 / C-11 production work generates short-lived gamma contamination on hands and clothing. The frisker reading at egress confirms the staff member can leave the controlled area without contaminating the corridor.
Theranostic centre — Lu-177 / I-131 therapy ward
High-activity Lu-177 and I-131 patient care produces beta-gamma contamination on protective garments. The frisker reads the staff member before they exit the patient room, before contamination is tracked into the wider hospital.
Radiopharmacy clean-room egress
GMP-compliant radiopharmacy clean rooms require contamination control at egress alongside gowning. The frisker integrates the radiation-safety check into the existing egress workflow.
Radioactive waste handling area exit
Waste packing, decay-store handling and shipping operations produce surface contamination. A frisker deployed at the waste-area exit catches an inadvertent dose-rate spike before it reaches the corridor.
Visitor / contractor egress check
Maintenance contractors and equipment-vendor engineers leaving the controlled area pass through the frisker before they exit the facility. The contamination record forms part of the visitor radiation-safety dossier.
Why Hand-Foot Contamination Monitor?
Traditional hand-foot frisker designs use proportional counters that need P-10 or methane flow gas. This unit uses smart scintillation detectors — no gas cylinder, no flow regulation, no consumable changeout, no annual gas-bottle scheduling. Lower running cost, simpler installation, no flow-gas safety dossier.
A single-pass hand measurement reads the palm side only. Active radiopharmacy work — twist-cap vial opening, syringe priming, glove-change sequences — frequently contaminates the back of the hand. The two-step protocol (palms, then turn over for backs) catches the contamination pattern a single-pass design misses entirely.
Standard Ethernet LAN connectivity means the frisker streams measurement events and alarm states into the central RMS without an add-on interface. The radiation-safety officer sees the contamination-event log alongside the area gamma, neutron and stack monitor traces in one console.
