Radiation Alert Ranger Description：

Datasheet Procedures

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.

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.

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.

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
