A “dirty bomb” is a radiological dispersal device (RDD) that is small, easy to hide and contains a radioactive material such as Cs137 and an explosive such as a stick of dynamite. RDDs are simple to construct. Terrorist groups would be interested in building dirty bombs because the components are available from medical waste and smuggled sources. An RDD would probably kill a small number of people in the explosion and would spread radiation over a limited area. Most of the nuclear hazard of an RDD attack would occur from people breathing radioactive dust. An RDD detonation would cause panic. According to the Congressional Research Service, costs to clean up from an RDD detonation could range from less than a billion dollars to tens of billions of dollars. Radiation exposure would be limited to those in the area of the detonation and downwind to the detonation. The radiation would be in the air and could easily be inhaled. People would be urged to shelter in place or evacuate the area. The area affected could range from .8 miles to more than 5 square miles. Unexploded RDDs can be found by “Interdiction” radiation detectors at a range of about 50 feet. Radioactive material such as Cesium 137 can be carried, undetected, by simple quadcopters and dropped into air intakes on buildings without an explosion.
An Improvised Nuclear Device (IND) is a crude nuclear bomb that creates an uncontrolled chain reaction using a fissionable material, such as highly enriched uranium or plutonium. The blast would result in an intense heat wave, bright light, increased air pressure and a release of radiation. If the IND detonates on the ground, the radioactive particles would be drawn up in a “mushroom cloud” containing dust and debris, according to the U.S. Department of Homeland Security. The radioactive dust-filled cloud could ascend up to 5 miles high. The range of a 10 KT IND plume could range from 700 to 3,000 square miles depending on wind direction, speed, and other environmental factors. The fallout plume would contaminate food and water supplies and change our daily lives for many years. The economy would be adversely affected by the resulting deaths, illnesses, loss of jobs, and destruction of workplaces and homes.
An undetonated IND can be detected, in most cases, with “Interdiction” radiation detectors. Most sensitive interdiction radiation detectors “saturate” or overload at low levels of radiation and can give false or no readings.
In the event of a 10-KT IND detonation in Washington, DC, a National Academy of Science paper reports it is likely that 45,000 people would perish immediately and 100,000 would be at risk of death. An additional 320,000 people would likely be seriously injured and another 175,000 could receive minor injuries. Damage to infrastructure would be measured in the hundreds of billions of dollars, according to Global Security.org.
FEMA has reported that in the event of a nuclear detonation, all people within a 50-mile radius would need to take shelter in the nearest most protective building or structure. During an IND detonation emergency, building managers would need detection equipment to assess contamination hazards. Immediately shutting off the air intake of building HVAC systems would minimize the risk of contamination for occupants and preserve a building's infrastructure.
A roof-mountedNukAlert® Automated Radiation Measurement Station (ARMS) offers building managers the ability to shut down their air intake systems when a threshold amount of radiation is detected outside. When used in combination with handheld NukAlert-ER detectors, building personnel can find safe areas for occupants to shelter after the threat is identified. And they can also check levels outside the building, if evacuation is required. If building occupants can shelter safely, the load on medical services can be reduced. The NukAlert ARMS-2 fixed radiation detector measures radiation falling to the ground and radiation clouds passing over the station in two simultaneous data streams. The measurements can be send to FEMA’s RadResponder Network and to WebEOC as well as other reporting applications.
TheNukAlert-Extended Range (ER) Geiger counter is a professional radiation detection instrument that measures Beta and Gamma radiation from 1µR/hr to 700R/hr with no saturation (overload) below 1,000R/hr. The NukAlert-ER can detect low levels of radiation from natural background levels to high levels of potentially lethal radiation near the explosion of a nuclear device or nuclear event. The NukAlert-ER has been tested by Oak Ridge National Laboratory and each ER comes with an individual calibration graph comparing your ER to the strict standards set by Oak Ridge National Laboratory.
TheNukAlert-ER Bluetooth Geiger counter sends radiation measurements to Andriod and iPhones using our Apps. The Bluetooth version also can sound audible alarms on Smartphones if a user defined radiation level is reached. The App can also report to FEMA's RadResponder Network, WebEOC, and other databases. A large numeric radation level display with color coded hazard level is easy to view and provides instant situation awareness.

The NukAlert-Extended Range(ER) is much more than a Geiger counter and Personal Radiation Detector. It is a vital tool that should be on every emergency response vehicle. Dirty bombs, Improvised Nuclear Devices (IND), and radiation accidents are a reality. Are you prepared or are you relying on radiation detection equipment that may be rendered unreliable in high levels of radiation? A recent report from the U.N.'s International Atomic Energy Agency (IAEA) says that missing nuclear and radioactive material may pose an attack threat if used in a dirty bomb or IND. Many radiation detection devices used for interdiction may be highly sensitive, but will become saturated and give false or erroneous readings in high levels or radiation when they are needed most. Reportedly, only 5 of the many Geiger counters at Fukushima nuclear disaster continued to operate following the release of high levels of radiation, the others became saturated (overloaded).
The NukAlert-ER radiation detector comes with a downloadable Windows application. The NukAlert-ER is in use by local, state, and federal agencies including the Dept. of Defense, Homeland Security, and ICE. Our products are available for purchase by government agencies under GSA Schedule 84.
The NukAlert-ER™ is an unique 'Extended Range' radiation detection instrument. It is a very sensitive Geiger counter that is also able to measure life-threatening radiation levels that are beyond the range of traditional Geiger- based devices. The NukAlert-ER accurately measures radiation over an extraordinary intensity range from 1µR/hr to 700R/hr. ±20% with no saturation (overload) below 1,000R/hr. It is a very sensitive Geiger counter, high range survey meter and a dosimeter, all in one instrument, with data collection, communications capability and adjustable dose and rate alarms. The ER is manufactured by an US company with more than 15 years experience in producing radiation detection devices. Tested at Oak Ridge National Laboratory.
The NukAlert-Extended Range™ Geiger counter uses sophisticated high-voltage control circuitry and performs statistical analysis of the pulses from the Geiger tube to enable radiation measurement over an intensity range from 1µR/hr to 700R/hr, with no saturation (overload) below 1,000R/h. This technique is referred to as "Time to First Count" in radiation detection textbooks. The result is a single device that can be used as a sensitive Geiger counter, survey meter and dosimeter. Its wide dynamic range facilitates the location of shelter, aids decontamination of people, allows preliminary evaluation of food, and measures windblown fallout from distant sources.
The NukAlert-ER™ can locate the source of radiation quickly through its numeric readout, audible alert, and bright flashing light to determine if you are in a life threatening situation.The NukAlert-ER helps emergency responders to determine if a scene is safe.
The NukAlert Automated Radiation Measurement Station (ARMS) is a roof mounted radiation measurment system that can send live radiation data to multiple user selectable databases, such as FEMA's RadResponder Network. The NukAlert Automated Radiation Measurement Station (ARMS) also accomplishes Task 5.5 of the Rad Resilient City Initiative. The ARMS station can also provide the data needed to shut down HVAC systems on buildings when a user defined radiation level is reached. The ARMS is an inexpensive device that can save employees lives and protect building infrastructure.
ARMS-2 is a fixed radiation measurement station with simultaneous "Sky Shine" and "Ground Shine" readings. The dual stream radiation measurements provide vital data on radiation in the clouds above the station and falling to ground to help emergency managers make vital decisions on "sheltering in-place" or evacuating. ARMS-2 should be placed on critical infrastructure near nuclear power plants, schools, hospitals, military installations, EOC's, office buildings, commercial buildings, and public buildings.
