Unlike scintillation detectors, the GM tube is sensitive to all ionizing radiation types: alpha (via thin mica end-window), beta, gamma, and X-ray. The cumulative dose function integrates pulses over time, converting counts to Sievert units using isotope-specific conversion factors built into the firmware.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDetects α (mica window), β, γ, and X-ray; dose rate 0.01–999 μSv\/h\u003c\/li\u003e\n\u003cli\u003eAlarm threshold user-configurable; audible + vibration + LED warning modes\u003c\/li\u003e\n\u003cli\u003eCumulative dose tracking (μSv, mSv) with time-stamped data logging\u003c\/li\u003e\n\u003cli\u003eUSB-C rechargeable 2200 mAh; backlit OLED display with real-time CPM graph\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eEvery purchase directly funds independent physics research at the Golden Physics Project.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003ch3\u003eExpert Analysis\u003c\/h3\u003e\u003cp\u003eA Geiger-Müller tube sensitive to all four ionizing radiation types — alpha, beta, gamma, and X-ray — is a meaningfully different instrument from the cheap beta\/gamma-only devices sold for casual hobbyist use. Alpha detection requires a thin-window tube, because alpha particles are the heaviest ionizing radiation and are stopped by millimeters of air or a solid metal tube wall. Full-type sensitivity means this instrument can characterize natural uranium ore, thorium-bearing minerals, and alpha-emitting contamination that cheaper instruments simply cannot detect. This is the specification that professional radiation safety personnel and serious mineral collectors actually require.\u003c\/p\u003e\u003cp\u003eThe integrated dosimeter function accumulates dose in μSv over time, making this instrument useful for extended monitoring in elevated-background environments — granite quarries, high-altitude flight, medical imaging facilities, and sites with naturally occurring radioactive material. The OLED display with real-time CPM graph gives immediate visual feedback on count rate variations, while the configurable alarm threshold protects against sustained exposure without constant attention. USB-C recharging and 2200 mAh capacity means extended field use without power anxiety.\u003c\/p\u003e\u003cp\u003eAt this specification level, this is the instrument that physicists, radiation safety officers, and serious geological fieldworkers actually carry. The combination of alpha-capable thin-window detection with full dosimetry and data logging in a compact unit represents genuine professional-grade functionality at a price previously available only to institutional buyers. For citizen science applications — radon mapping, mineral characterization, or environmental monitoring — this is the correct tool.\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54144345506084,"sku":"GPP-RAD-GEIGER-PRO","price":219.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/960px-Geiger_counter.jpg?v=1781220459","url":"https:\/\/shop.goldenphysics.org\/products\/professional-geiger-counter-dosimeter","provider":"Golden Physics Project","version":"1.0","type":"link"}
