NukAlert Automated Radiation Measurement Station (ARMS) is designed to mount on a roof of a building. The ARMS provides 27/7 fixed radiation monitoring and if a user defined level is reached, the ARMS can connect, through BACnet, to shut off to the HVAC system. ARMS reports live to multiple databases including FEMA’s RadResponder Network and WebEOC. ARMS can send email and text notifications.Range: 1µR/hr to 700R/hr with no saturation below 1,000R/hr, UPC: 858628004302

The NukAlert Automated Radiation Measurement Station (ARMS) is a simple, fixed radiation device for continuous reporting of radiation intensity. The ARMS can initiate shutdown of building ventilation systems when a user-defined radiation level is detected. Fallout particles are captured and held in the 1 square meter filter bed for measurement. The three layer filter simulates the properties of soil for fallout collection. An artificial turf top layer catches large lightweight particles and ash, preventing wind from blowing them off the platform. The middle absorbent layer holds up to 7mm of rainfall to retain soluble isotopes. Particles as small as 1 micron are caught by the lower filter layer. The replaceable triangular filter frames are reinforced with a metal mesh.
The vertical pipe section houses the sensitive radiation detector, Gateway communication device, Power Over Ethernet (POE) splitter, and environmental control. ARMS power and communications are sent through a single Cat 5 Ethernet cable. Lightning protection is provided at the mid span POE injector / lightning arrester. Cat 5 cable or fiber optics may be run from the POE injector to the Internet router. The station can feed data in ANSI N42.42-2012 format to multiple database URLs simultaneously.
The measured dose rate can be read as a BACnet analog value by compatible building control systems (BAS) for alarming and automatic shutdown of building ventilation (HVAC) when radiation above a set threshold is detected. The NukAlert ARMS is able to autonomously send radiation reports to multiple databases including FEMA’s RadResponder Network. Additionally, the ARMS can send email and text reports of radiation levels to multiple key building personnel. The NukAlert ARMS accomplishes Task 5.5 of the Rad Resilient City Initiative.
With the NukAlert ARMS, you can monitor the actual radiological environment at your location and remote sites without sending anybody outside to take measurements. During a radiological event, if fallout is drawn in by the ventilation system, the shelter offered people by a building can be compromised and the building may be rendered permanently uninhabitable by radioactive dust distributed in the ductwork. The NukAlert ARMS can protect the building and its occupants by initiating the closure of outside vents the moment elevated radiation is detected.
