Handheld Geiger counter with a halogen-quenched pancake GM tube (45 mm effective diameter, 1.5–2.0 mg/cm² mica window). Alpha, beta, gamma and X-ray detection in one instrument. Sensitivity 3,500 CPM per mR/hr referenced to Cs-137. Multi-mode display in µSv/hr, mR/hr, CPM or CPS. ≥ 3,500-hour battery life on a single AA — the field-survey workhorse for laboratory and inspection work.

The lab + field workhorse — battery life is the differentiator
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.
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.
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.
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.
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.
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.
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.
