Radiation and Chemical Detection/Identification

D-tect Systems offers a rugged, field-ready line of equipment designed for accurate radiation detection and identification as well as chemical analysis. Our products are used widely by security personnel and first responders to combat the threat of dirty bombs, radioactive hazmat, nuclear device components, and toxic industrial chemicals. They are used at security checkpoints to inspect for dangerous materials, hospitals to monitor and track radioactive waste, and landfills to check for hazardous materials. Our personal radiation detectors are carried by thousands of professionals every day.

Our mission is to provide our customers with the most powerful, affordable, and deployable security products available.

The radiation detectors, radiation identifiers, and chemical identification equipment we offer are exceptionally fast and sensitive. They are engineered for and proven in the intense situations familiar to first responders. Intuitive design and large, bright displays support security personnel in making correct split-second decisions.

When there are important questions about possible radiation or chemical substances, turn to D-tect for fast, reliable answers – in the field, on the move and on location, anywhere monitoring activities require them.

The Sentry-RMS is a high-security networked monitoring station that allows real-time sensor and video monitoring by multiple operators across secure and encrypted data links. The PC monitoring software is easy to use and data and video logging is automatic.


The MiniRad-DX is a our newest personal radiation detector. It features a full color LCD screen on the face and a bright OLED screen on the top for quick and easy monitoring. The MiniRad-DX runs on the DX network that is extended by each MiniRad-DX that is connected to it.


The Rad-DX is a mesh networked radiation detector with sensitive scintillator crystals that can be mounted just about anywhere. The Rad-DX runs on the D-tect SensorNet, allowing the user to monitor a full network of Rad-DX units from a tablet or PC. Data including dose rates can be viewed real-time or from past event logs.


The MiniRad-D is a rugged, all-weather radiation detector that’s small enough to wear on a belt yet powerful enough to quickly locate low-level radioactive sources. It automatically calibrates to background radiation and features audio and vibrate modes.

DX-Dashboard software is web-based and is used to monitor and control a Rad-DX network remotely. It runs on either the D-tect Cloud Server or the DX Network Assistant (if installed at your facility). Using DX-Dashboard, you can access your Rad-DX network using any web-enabled device (smartphones, tablets, PCs). To access the network, you will only need to input your username and password.


The DX-Assistant is a software appliance that installs within your existing network and allows the full range of DX interface and communication tools to be operational behind your secure firewall, including the DX-Dashboard user interface, smartphone and tablet monitoring and control, and email notification.


DX-View is a PC based software program specifically designed to monitor Rad-DX radiation detectors. The DX-View software is also used to view and download data from one or more Rad-DX radiation detectors. Using this software, you can set radiation alarm levels, view a real-time graph, and download historical data.


The DX-Link is a small wireless USB device designed to facilitate mesh communication with one or more Rad-DX detectors. These devices can be used to replace the USB cable between a PC and Rad-DX, as gateways to monitor an entire Rad-DX network, and as an intermediary or 'repeater' to improve the signal strength of the mesh network.

Rad-DX NEMA Enclosure

The Rad-DX has a version that is built into a NEMA Enclosure. This rugged, heavy duty enclosure includes two higher gain antennas, a longer lasting backup battery, and a cooling fan. Mounting holes are positioned in strategic locations for easy installation. This enclosure is an excellent way to monitor an extensive outdoor facility.


The MiniRad-V is a personal radiation detection device that is designed for use aboard a vehicle. Housing a sensitive Cesium Iodide scintillation gamma radiation detector, the MiniRad-V is powered directly by your vehicle.


The Rad-D is a fixed-position radiation detector designed to monitor doorways, driveways, or loading docks. This device can inspect packages or luggage on conveyor belts, and transimits information via Bluetooth or serial communication to a central control unit.


The Rad-ID is an advanced hand-held gamma and neutron radiation detector and identifier, a radiation laboratory-in-a-box that is easy to use with almost no training. Identification of 91 different isotopes is possible with the press of a button.


The Chem-ID is a highly accurate and reliable field chemical detector and identifier engineered to both identify and provide a detailed chemical analysis of over 100 chemicals. The device can be operated by remote control and is Bluetooth capable.


The Rad-DXG is a fixed-position radiation portal monitor. A ruggedized, industrial grade monitor which can link into an existing Rad-DX network, controlled with the mounted touch-screen display and monitored via the DX-View or the DX-Dashboard software.

Rad-DXG Portable

The Rad-DXG Portable is a portable radiation portal monitor designed for mobility and quick deployment. It includes 2-4 individual detectors mounted in the frame. It is controlled with the mounted touch-screen display, can connect to an existing Rad-DX network, and monitored via the DX-View or the DX-Dashboard software.
