Solid State Replaces older CDS cell technology found in other keychain-style detectors with a high-grade photodiode /scintillator w/linear photodetector & direct conversion. This eliminates temperature sensitivity induced false-alarms and slow 3-5 minute low-level reaction time found in other keychain-style detectors. This new technology adds the capability of detecting Beta radiation such as strontium-90 (possibly in a dirty bomb) and radioactive iodine (I-131) emitted from a nuclear reactor accident or fallout from a nuclear bomb.
Real-World Applications! Dirty Bomb Detects Cesium-137, Iridium-192, Thallium, Cobalt-60, Strontium-90. The ONLY keychain-style personal radiation detector that detects Beta radiation, which includes Strontium-90, a grave concern for dirty bombs (see below).
Nuclear Reactor Accident or Nuclear Bomb Fallout Detects both high energy Gamma and Beta radiation from released from a nuclear accident/attack. With the presence of I-131, emergency heath officials may call for the administration of potassium iodide.
Wide alarm range 75mR/hr to 2000R/hr. (Other keychain-style detectors detect only 100mR/hr to 50R/hr.)
Affordable Low retail cost compared to other commercially available units with less features.

RadDetect ACG1250 Personal Radiation Detector F.A.Q.
Why would I need a RadSense Personal Radiation Detector? The effects of Hurricane Katrina have proven that self-reliance is a necessity for survival of a disaster. In the event of a dirty bomb attack, nuclear reactor accident/attack or nuclear/suitcase bomb detonation, prompt detection of radiation levels in your area by emergency officials is of utmost importance. One would hope that they are in your area with their equipment as quick as possible and that they report this information to the public immediately. Of course, they cannot follow you and your family around with their detectors and tell you if you specifically have retreated to a safe environment away from the radiation. A back-up to the reliance on emergency officials would be the possession of a personal radiation detector to alert you to harmful levels of gamma, beta, fast-neutron and x-ray radiation.
How does it work? A dual-mode sensor. Direct Conversion and High-grade scintillator w/linear photodetector (indirect).
Direct Conversion - When a radioactive photon strikes a depletion region created by reverse bias on the photodiode, it produces a small amount of charge in proportion to the photon's energy. The resulting signal is then amplified and processed by the CPU in the RadDetect™. (Detectors that convert incoming radiation directly into the electrical signal are called direct conversion type detectors)
Indirect Conversion - Incoming radiation is converted by a scintillator material in our indirect conversion type detector, where the radiation energy is first converted into the visible light. The visible light is then captured by the photodiode and converted to an electric signal. The resulting signal is then amplified and processed by the CPU in the RadDetect™.
What types of radiation will it detect? Exposure to gamma, beta, fast-neutron or x-ray radiation of 75 milliRoentgens per hour (mR/hr) is sufficient to trigger the low-level auto-alert. This includes Strontium 90, Cesium-137 and Cobalt-60, commonly available radioactive materials likely used in a dirty bomb (also called a radiological bomb). It will also detect radioactive iodine released from a nuclear reactor accident or fallout from a nuclear bomb.
So it detects Beta radiation? Yes. And of course, this is required for detecting Strontium 90 (possible dirty bomb radiation) and detecting beta emitters from radioactive iodine (I-131) from a nuclear reactor or nuclear bomb. The RadDetect is the only commercially available keychain-style personal radiation detector that detects Beta radiation.
Will it tell me what type of radiation I am being exposed to? Though the RadDetect™ detects gamma, beta, fast-neutron and x-ray radiation, it alerts you only to the presence of radiation, not the specific type of radiation.
How many levels of detection does the RadDetect have? 256 detection levels - Beeping and flashing of the auto-alert occurs at 256 varying rates of speed (similar to a Geiger counter or metal detector). This level of instant preciseness makes the directional feature very easy to use. PLUS - Pressing the gray diagnostic button allows for additional instant analysis of exposure level (low - mid - high).
If the RadDetect instantly alerts me to radiation, what do I do next? Use the unit's directional feature to escape to a safe area: An unmatched benefit of the real-time auto-alert capability of the RadDetect™ is that by holding the unit vertically - with the gray diagnostic button facing you - and slowly turning in a circle, you are able to monitor the real-time increasing/decreasing auto-alert rate (as described above), allowing you to determine the direction from which the radiation is coming. This allows you to move in the other direction away from the radioactive source. It will instantly cease alerting when your radiation exposure reaches a safe level. This feature is possible because the microprocessor samples the air 32,768 times a second and gives you instant feedback of the current radiation levels.
Will the RadDetect tell me from which direction the radioactive source is coming? Yes. It has a directional feature which will guide you away from the radioactive source.
Will it detect a dirty bomb before it detonates? Yes, if the dirty bomb (a.k.a. radiological bomb) is emitting detectable levels of Beta or Gamma radiation (of which it likely would). Of course, the RadDetect would have to be in the vicinity of the dirty bomb to detect the radiation.
What is the detection range? 75mR/hr - 2000R/hr (0.75mSv/hr - 20Sv/hr). This is far greater than other personal radiation detectors.
Are there any devices or appliances that it should be kept away from to prevent damage to the device? No. The RadDetect cannot be damaged by other devices.
Does it detect EMP (electromagnetic pulse) from power lines or microwaves? No. The RadDetect detects radiation, not electromagnetic pulses.
What is its size and weight? 3" x 1.25" and less than an ounce. About the same size and weight as a car's alarm key fob (the keychain unit that unlocks/locks your vehicle's door).
Can I attach it to anything besides a key chain? Yes. You can attach it to a purse, backpack, laptop case, etc. Use of a carabiner is good for this application.
Can I test the unit myself? The unit cannot be tested with any home source. While the RadDetect was specifically designed to only detect natural radioactive sources, it has been configured to report the existence of low-energy x-rays from a dental or veterinarian X-ray machine for demonstration purposes. The X-ray machine must be able to provide continuous rays for more than 1 second. Most modern X-ray machines are configured to be operated for only a fraction of a second, quite possibly a millisecond, so you must manually select a long duration (i.e.: 3 seconds): The RadDetect should be placed as close as possible to the output of the head because most X-ray machines are pulsed. The RadDetect's alarms will trigger soon after the X-ray source is turned on and will cease as soon as they are turn off or removed. Testing should only be done by a person trained to use X-ray machines and ACG Security accepts no responsibility for anyone who attempts to test their RadDetect with a radioactive source.
Will the RadDetect give false alarms due to temperature changes and static electricity like other keychain detectors? No, it won't sound a false alarm. The RadDetect uses the most recent innovations in radiation detection technology and does not use older CDS cell technology like some other commercially available units.
Will the RadDetect function after being subjected to an EMP (electromagnetic pulse)? The RadDetect has been tested and will function like any other small electronic device after being subjected to ground-level EMP and High-altitude EMP (HEMP). The RadDetect was tested with both a Marx Bank Generator and Voltage Gradient Tests up to 145 KeV and exceeds MIL-STD-461D specs. Note: A dirty bomb will not emit an EMP.
How is the RadDetect calibrated? The RadDetect sensor is tested with a small Cesium source and a DSO to ensure disintegrations are detected. Then, the sensor is subjected to low-energy x-ray radiation to determine the sensitivity to a source that would be moderated (a Beta source in a steel jacket for instance). A program, uploaded to the RadDetect through a programmer's port, then sets the threshold levels in the processor. A programmer's port is absolute necessary to accurately calibrate any detector as moderated radiation is easily blocked/attenuated by thick plastic and many other compounds. The RadDetect is tuned to detect the lowest energy level that most other sensors (calibrated with Cesium) cannot detect.
I stock potassium iodide for radiation emergencies. Does the RadDetect detect radioactive iodine from a nuclear reactor release or fallout from a nuclear bomb? Radioactive iodine (I-131) emits beta and weak gamma radiation. Because the RadDetect detects both types of radiation, it will detect radioactive iodine from a nuclear reactor release or nuclear bomb. This is the only keychain style radiation detector that will do so.
How about civil defense meters or Geiger Counters. Won't they work just as well? Geiger Counters max out (report no radioactivity) at rather low levels. These devices are only used by clean-up teams after most of the radioactive fallout has been removed from an area. They are used for final decontamination. Civil Defense Meters are obsolete though they are still being sold by some vendors and still in use in the field today (in some areas). In addition to the lack of linear reporting, these meters' parts are approaching 30 years old - well beyond the component lifetime - are unreliable and have been phased out by most governments including the U.S.
Who would benefit from the use of the RadDetect™? Aside from civilian use for personal protection, the RadDetect is designed for: First responders to radioactive threats; Customs and border patrols; Law Enforcement; Security officers in nuclear power facilities, banks, government laboratories, medical facilities; Military; Government agencies;
Is the RadDetect™ a "one time" use device? No, the RadDetect will continue to function within specifications after being exposed to radiation. The RadDetect contains a real-time alerting mechanism so that its user can find a safe place to move away from the radioactive isotope. Obviously, the unit will not work if it is annihilated by a nuclear blast.
Does the RadDetect™ have an ON/OFF Button? No, the RadDetect radiation detector cannot be turned off unless you remove the battery. The RadDetect was designed to virtually eliminate any possible human error. If the user approaches a dangerous radioactive isotope, the RadDetect will instantly sound an alarm.
Do you have to press the button to make it work? No, the RadDetect scans continuously without user intervention.
What is the function of the button on the RadDetect? If the diagnostic button is quickly pressed and released when the RadDetect is auto-alerting you to the presence of radiation (as described above), the 256 ‘flash and beep’ auto-alert levels will pause momentarily. The red LED light on the front of the RadDetect will then flash at different rates (view chart) to alert you to your current minimal level of radiation exposure measured in Roentgens per hour (R/hr). This LED ‘exposure-level’ alert is flashed each time you press and release the diagnostic button. (No audible alert will be heard). After the release of the button the RadDetect will then revert back to the beeping/flashing auto-alert mode using 256 detection levels.
During normal function (no radiation present) the RadDetect’s functionality can be confirmed by pressing and holding the gray diagnostic button. The microprocessor will illuminate the red LED and will turn it off when the diagnostic button is released. No audible alert will be heard.
What alarm systems does the RadDetect™ have built in? The RadDetect has a flashing red LED light and a 70 dBa audible alert.
Is it safe to put through airport security systems and X-ray package/vehicle scanning equipment, etc.? Yes, it is safe. The RadDetect is tuned to ignore, and cannot be damaged by, artificial radioactive sources like package canners and x-ray equipment used by airport security. It can be used around and near scanning equipment without the hassles of false alarms, and without interfering with the scanning equipment.
Can the battery be replaced in the RadDetect™? The user-replaceable battery is a standard CR2032 lithium coin battery available almost anywhere batteries are sold.
How long does the RadDetect's battery last before replacement is needed? Due to the RadDetect's unique air sampling of 32,768 times each second (this enables the Directional feature and instant alerting feature), the inexpensive user-replaceable battery should last more than 6 months under normal use.
What happens if I put the battery in the wrong way? Although care should always be taken when installing batteries in any electronic device, in the case of the RadDetect it has built-in reverse battery polarity protection.
At what temperature range will the RadDetect™ continue to function? The RadDetect can operate within a temperature range of -22°F to 140°F (-30°C to 60°C).
How can the RadDetect be of assistance to Law Enforcement, Fire/Hazmat & Homeland Security Personnel? The RadDetect is an always-on personal protection, threat detection device. Though its been called a dirty bomb detector or micro bomb detector, it is not limited to the detection of dirty bombs. There is an increasing concern over "orphan" sources, lost or undocumented sources that could be used for malicious purposes. The RadDetect is always working so an officer will be instantly alerted to the presence of a hazardous source within his/her immediate vicinity that is potentially causing physical harm. This allows the officer the opportunity to assess a situation that may otherwise have been completely unknown, since radiation cannot be seen, smelt, felt, or tasted. Fire/Hazmat personnel can also feel safe that they will be warned if walking into an unmarked radioactive area while in the process of their normal duties.
Can the RadDetect be used inside a moving vehicle? Yes, the RadDetect works well inside vehicles. The detection sensitivity of the RadDetect inside a moving vehicle depends on two key factors: The amount of shielding, and the speed at which the source is moving relative to the RadDetect.
How durable is the RadDetect? The RadDetect is water resistant (but you should not submerse it in water), has an outer shell of high-impact ABS, and can withstand an electro-magnetic pulse (EMP) of 145Kev. It should handle most weather conditions its user would experience.
Will the RadDetect ignite a dirty bomb? Absolutely not. Unlike some other radiation detection equipment, our bomb detectors do not internally generate high voltages for their sensors. The maximum potential inside the RadDetect is 3V, and it draws less than 100uA most of the time. It does not create any sparks or RF (radio frequencies) that could ignite a bomb.
How fast do the sensors react? Monitors 24/7 and instantly reports (less than a second) when radiation levels are rising and falling so you know when you are in a safe area.
Where is the RadDetect manufactured? Parts are manufactured in the U.S. and Canada. Final individual testing and calibration is in Canada.
What is the warranty on the RadDetect? 1 year limited warranty. Parts and labor.
What does the warranty not cover? The limited warranty shall not extend to water damage or damage caused or occasioned by exposure of the product to a corrosive environment. Nor shall this warranty extend to physical damage caused by misuse, abuse, or service by anyone other than the manufacturer’s authorized representative, or damaged due to accident or act of God.
How can the RadDetect be calibrated to react to a dental x-ray machine, but not react to an x-ray machine at the airport baggage screening? The airport x-ray screening machines use very short duration pulses and rely on luminescent screens to "hold" the image. This is how film is not destroyed or damaged by airport screening machines but would be destroyed if exposed to a dental unit. A dental x-ray machine is a continuous x-ray generator (at 60Hz) for a specific duration depending on what is being photographed. Even with this method, the RadDetect must be very close to the machine and must be turned on for at least 2 seconds.
Can I silence the alarm during an on-going radiation emergency? If you are in a constant state of radiation exposure and wish to silence the alert, just open the housing and remove the battery. The included manual will instruct you how to easily open the unit.
