Applications
The lab + field workhorse — battery life is the differentiator
Laboratory bench survey
Routine wipe counts and surface checks at the dispensing bench, fume hood and dose-calibrator well. The 40-hour maximum count time supports the long counts low-activity sealed-source wipes need.
Field survey + inspection
AERB / state RSO inspection visits to hospital radiation facilities. The single-AA battery life means the instrument carries through multi-site inspection days without battery anxiety.
Theranostic patient release
Lu-177 / I-131 patient discharge surveys — verify dose-rate at 1 m from patient and at the room surface. The 1,100 µSv/hr ceiling covers the patient-discharge regime.
Contamination response
When a hot-lab spill or positive-frisk event happens, the inspector arrives with the Inspector Alert — surface readings localise the contamination before clean-up begins.
Multi-modality teaching
Nuclear-medicine technologist and radiopharmacy trainee programmes use the Inspector Alert as the introductory hands-on radiation-safety instrument — robust enough to survive trainee handling, accurate enough to teach with.
Sealed-source storage audit
Annual AERB audit of sealed-source storage cabinets — verify dose-rate at cabinet surface, log the reading via the 3.5 mm output, file in the inspection dossier.
Why Inspector Alert™ Geiger Counter?
A single AA alkaline delivers ≥ 3,500 hours of operation. The instrument lives in the bench drawer between inspections — no rechargeable battery to forget on the charger, no scheduled-replacement reminder. Pick it up, survey, drop it back; the next user finds it ready.
A 45 mm effective diameter is large enough to read surface contamination at a practical distance from a moving probe. Smaller pancake probes miss intermittent hot spots during a fast walk-survey; the Inspector Alert's wider window admits enough activity that the spot lights up at walk speed.
NIST-traceable Cs-137 calibration produces the published 3,500 CPM/mR/hr sensitivity figure — comparable across manufacturers and against the published handbook values for nuclear-medicine isotopes. The calibration certificate is the AERB inspection-ready document.

FAQ
Handheld Geiger survey meter — questions we hear from Indian NM RSOs
What routine surveys the Inspector Alert covers, why pancake-GM beats scintillation for wipe-survey work, audible / visual feedback for hot-spot detection, and the annual calibration cycle.
Q.What routine surveys does an Inspector Alert cover in an Indian nuclear-medicine department?
Daily hot-lab bench-wipe surveys before opening the dispensing line; morning survey of the generator elution station; area dose-rate check at the injection room, waiting area and patient toilet; post-therapy patient-release survey; incoming-package survey when a Tc-99m generator or Lu-177 shipment arrives. The Inspector Alert is the handheld pancake-GM detector that reads each of these in a single walking survey.
Q.Why pancake-GM instead of a scintillation detector?
A pancake-GM has a thin mica window (~1.5 mg/cm²) that lets low-energy beta particles through — critical for detecting Tc-99m, F-18 and pure beta emitters like Y-90 and P-32 on the surface. A shielded scintillation detector reads gamma dose rate but misses beta surface contamination. For hot-lab wipe survey work the pancake-GM is the standard configuration.
Q.What audible / visual feedback does the operator get on a routine survey?
Real-time click rate rising as the probe approaches contamination — the operator hears the hot spot before the eye finds it. Configurable alarm threshold audibly / visibly signals when the count rate crosses the department's action level. A large LCD display shows numeric count rate and cumulative counts for the wipe-test workflow.
Q.How is Inspector Alert calibrated and how often?
The detector ships with a Cs-137-calibrated reference and a NIST-traceable calibration certificate. Annual re-calibration is the standard cycle for a hot-lab survey meter under the AERB Safety Code framework. Saxsons offers the re-calibration service so the meter stays inspection-ready.
Q.How is Inspector Alert supplied and supported in India?
Distributed across India by Saxsons Group. Supply covers the survey meter, calibration certificate, applications training and annual re-calibration service. Imported under CDSCO Medical Devices Rules 2017.
