Nuclear radiometer Alpha Beta Gama sensitive geiger-muller mica pancake SI-8b

Description: This radiation detector is built on the Soviet military Geiger-Müller mica counter SI-8b (СИ8-б) We have three types of this device with High Alpha sensitivity (this device), medium and low Alpha sensitivity (look at other us listing) Look at the photo with smoke sensor with AM241 to see what sensitivity of current device. Key Features: The detector features a Geiger-Müller sensor with an end window made of a thin mica layer. This design provides high sensitivity to low-energy ionizing radiation (β rays), as well as α and γ rays. Thanks to multiple filter covers, the device can separately detect α, β, γ, and X-ray radiation. Another advantage of this type of sensor is its high detection speed due to the large surface area of the sensor. On average, the sensor produces 2-3.5 CPS (in normal radioactive background), which means that with a confidence level of sigma σ =2 (95%), the device provides results with an accuracy of ±25% in just 40 seconds. Specifications:Alpha sensitivity is low. β, γ, and X-ray similar with SBT10A.Battery Life: >400 hours (with display backlight off, temperature 20°C, background <20μR/h)Li-Polymer Battery: 3.7V 1200mA/HLCD: 1.3" monochrome, clearly visible in sunlightCharging: Type-C 5V 1A MaxSensor: SI-8bThe body has a mounting bracket for a tripod with an M6 x 6mm screwAudible and visual indication of particle detection Functional Features:Measurement Modes:Search Mode: ≈ μR/H, CPS (high response speed, adjustable response speed in settings)Total Measurement Mode: Σ μR/H, CPS (high accuracy due to measurement over a specific exposure time)Separate Measurement Mode: Σ: α β γ, CPS (allows separate measurements for different types of radiation using different filter covers; measurement can be ended manually or based on exposure time)Settings:Brightness: 1-15Exposure Time (HH:MM:SS): 99:59:59 - 1 second (after this time, an audible alarm will sound and the measurement will end)Sound: 0-9Alarm: off/onAlarm Trigger Level: 10μR/h - 9990μR/hSensor Settings:Number of cells per second for averaging results in search mode (average run algorithm)Number of pulses after which the number of cells decreases (for fast reaction to increasing radiation in search mode)Transformation coefficient to convert CPS to μR/h (this coefficient can be reduced by a factor of 100 to get values in μSv/h; however, the display will still show μR/h)Display Contrast Settings The device functionality and user manual are in English. Package Includes: The device itselfShock-resistant case Set of filters for separate measurement: Grid cover, (other filters are installed in it) Black paper (β +γ) Red steel (γ) Handle with M6x6 screw attachment, 90mm length User manual in EnglishAdditional :Double telescopic handle, it is compact 170-840mm Genuine leather waist belt cover (made to order in 7-14 day) Warranty:The device, including the sensor, is covered by a 1-year warranty from the date of receipt.The cost of shipping for device repairs or returns due to other reasons is the buyer’s responsibility.In case of device malfunction, you can receive free repair advice if you choose to repair it yourself.The Geiger-Müller sensor has a thin mica window that can be easily damaged by contact with foreign objects; such damage is not covered by the warranty and the item cannot be returned in this case. We recommend recording a video of the unboxing and powering on of the device to avoid disputes. (If the device arrives damaged, you have 7 calendar days from receipt to contact us and resolve the issue.) Delivery: The default delivery method is air delivery by priority package, with a tracking number. If you wish to select a different delivery option not listed, please contact us, and we will try to add a suitable option. Important information for buyers from Australia, Oceania, Central Africa and South America: due to increased shipping cost to these regions, shipping price is calculated individually. If you need other delivery method, provide the postal code, country, city. Frequently Asked Questions:✓ What is the difference between this unit on the SI-8b and the variant on the SBT-10A? Form factor: SI-8b pancake SBT-10 is rectangular SBT-11 is rectangular Sensitivity to alpha radiation when measuring one sample: SI-8b ~60-600 cps. (this device ~531 cps) SBT-10 ~70-1000 cps SBT-11 ~400-1200 cps ✓ How does the Separate Measurement Mode Σ: α β γ work?In Σ mode, perform a measurement with the cover removed, press the pause button, install the β+γ filter, and continue measuring. Pause again and install the γ filter. By conducting these 3 measurements, you get 3 values for α, β, and γ radiation displayed on one screen. The device automatically subtracts the values of these 3 measurements and shows the result. From the start of the measurement, wait for some time (exposition time who can select in settings, or manually stop) to achieve low measurement error. ✓ What is the condition of the sensors included with the radiometer?We use only new sensors from stock that have never been used and have passed testing. ✓ Where can α radiation be encountered in everyday life?In places with poor ventilation and those located underground, such as parking garages, basements, tunnels, and pits, where radioactive radon gas, a source of alpha radiation, can accumulate.Some smoke detectors use an ionization smoke sensor, such as the one shown in the photo. (Often this is Am241.) ✓ Why do we recommend recording video during unpacking and testing the device upon receipt?During transport, especially by air, there is a small chance that the aircraft's cabin might be depressurized at high altitudes, which could lead to the Geiger-Müller counter exploding due to its very thin mica window that maintains a vacuum inside the sensor. While this does not pose a risk to the aircraft, it can damage the sensor.
