Radiation Alert Ranger
The Radiation Alert Ranger® offers maximum performance in a lightweight, rugged nuclear radiation detector for surveying at the facility or in the field. Though designed with industrial environments in mind, it still has all of the features you’ve come to love in the lab. The Radiation Alert Ranger® is a small, handheld, digital survey meter that offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays.
This model has built in efficiencies for common isotopes to calculate activity in Bq and DPM. This Ranger radiation detector also has a backlit digital display, a red count light, and a beeper that sounds with each count detected. Other features include selectable alert levels, an adjustable timer, and an optional wipe test plate for swipes.
Free Observer USB Software
Free Observer BLE Software For Use With The
Optional Bluetooth Module
Internal memory and the free Observer USB Software (Windows® only) allow you to download your data, and set computer alarms. With the optional Blue Tooth module you can download Free Radiation Alert® Observer BLE app from the Google App Store, where you can display the readings from your detector on your android device, label sample readings and descriptions, take timed counts, append GPS data and send your saved survey file. Alarms set on the instrument will also activate on your android device.
Applications & Uses: Surveying for NORM (Naturally Occurring Radioactive Material) contamination, Gross wipe counting, Contamination surveys of packages, equipment, people, etc., Regulatory inspections, Scrap Metal Screening, Low energy radionuclide detection

Detector
Operating RangemR/hr – .001 (1µR) to 100 CPM – 0 to 350,000 µSv/hr – .01 to 1000 CPS – 0 to 5000 Total Counts- 1 to 9,999,000 counts |
|
Energy Sensitivity
Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the detector window. 3340 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 µCi at contact.
Built-in Efficiencies
Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha
Display
Graphic LCD with Backlight
Anti Saturation
Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.
Averaging Periods
This radiation detector display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases.
