handheld geiger counters

Modernized Geiger counters for personal radiation detection

Our portfolio of Thermo Scientific RadEye personal radiation detectors offers the functionality of traditional Geiger counters while delivering features not available in traditional Geiger counters.

These lightweight instruments offer an improved range of detection of multiple types of ionizing radiation—alpha, beta, X-rays, and gamma—even in the same unit. They feature an easy-to-use, common interface and are compatible with a catalog of optional accessories for wireless reachback, rechargeable batteries, and extension poles to maintain good ALARA principles.

Variations include Geiger counters that can monitor dose rate, stay time, and peak values. Intrinsically safe options are available for users working in potentially explosive environments.

Portable Geiger counters by application

Our series of Geiger Müller–based radiation detection products were designed with your specific mission in mind. Useful information such as peak count rate and dose rate values, energy compensated dose rate, accumulated dose, and remaining stay time help keep your mind on the mission, not on your instrument.


We provide a single source for global integrated service, support and parts supply for all your radiation, measurement and security products.
