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.

FAQ
Hand-foot contamination monitor — questions we hear from Indian cyclotron RSOs
Why the hot-lab exit check needs a fixed monitor, why α + β + γ coverage matters when the lab handles Lu-177 / Y-90, what release-limit sensitivity actually delivers, and the audit trail for AERB inspection.
Q.What routine problem does a hand-foot contamination monitor solve at the hot-lab exit?
Everyone leaving a radiopharmacy hot lab has to verify their hands, feet and clothing are contamination-free before crossing back into unrestricted areas. Without a fixed exit monitor, that check falls to a hand-held survey meter and operator diligence — inconsistent and often skipped when the shift is busy. A fixed hand-foot contamination monitor at the exit makes the check part of the physical geometry: the person stands on the foot-detector plates, places hands on the palm detectors, waits for the pass indicator. Skipping the check means not being able to leave.
Q.Why alpha + beta + gamma detection instead of gamma-only?
Different isotopes in the radiopharmacy leave different contamination signatures — Tc-99m and F-18 are gamma emitters, Lu-177 and Y-90 have significant beta emission, and research alpha emitters (Ac-225, At-211 in specialised centres) leave alpha contamination. A gamma-only monitor misses beta and alpha contamination completely. An α / β / γ frisker covers all three so no contamination mode is invisible at the exit.
Q.What detection sensitivity does the monitor need to actually be useful?
AERB Safety Code for Nuclear Medicine Facility and cyclotron facility framework set contamination-release limits per isotope class. The HFCM detects surface contamination at levels well below those release limits, so a pass reading actually means the person is at or below the AERB threshold — not just "no obvious contamination". Reading sensitivity is what makes the monitor a compliance instrument rather than a symbolic gate.
Q.What audit trail does the HFCM produce?
Every measurement is logged with timestamp, operator ID (badge or PIN), reading value and pass/fail decision. The log feeds the RMS server for facility-wide audit visibility. AERB inspection reads that log to verify the exit-monitor policy is actually being enforced — not just that the monitor is on the wall.
Q.How is the HFCM supplied and installed in India?
Distributed across India by Saxsons Group. Supply covers the monitor, site-fit assessment (typically installed at hot-lab exit, radiopharmacy exit and cyclotron-vault exit), RMS integration, commissioning against AERB Regulatory Requirements for Medical Cyclotron Facility and India commissioning support.
