PM-1401GN手持β中子监测器
The PM-1401GN is designed to search for, detect, and locate radioactive and nuclear materials in a variety of situations. Due to the ease of operation, these units are ideal for Customs, Law Enforcement Officers, and other emergency services personnel.
The PM-1401GN is a small handheld radiation detector with separate detectors for both gamma and neutron radiation. It is a small, lightweight, and very simple to operate unit designed specifically for the detection of SNM. It comes equipped with a belt clip allowing hands free operation. For more severe environments, an optional nylon holster is available.
