AT2327
Radiation monitoring system

Alarm radiation monitoring system AТ2327 can be used for constructing a flexible and multichannel stationary system for radiation monitoring of radiation-sensitive and radiation-dangerous sites, areas and facilities, as well as for radiation monitoring of environment.

Application
