It should be able to detect small amounts of explosive material.
Detectors must be able to distinguish between harmless items and those containing explosive material. This means that they need to be able to detect very low levels of explosive material. In addition, they must be able to operate reliably under adverse weather conditions.
The U.S. Army has been working on developing a new type of bomb detector since the 1980s. These detectors are called Explosive Detection Systems (EDS). EDSs use sensors to detect the presence of explosives. Sensors are devices that measure physical properties such as temperature, pressure, light, sound, and electrical current. Explosives emit different types of radiation than other materials. For example, TNT emits alpha particles, which are charged particles that can penetrate most objects. When an object contains TNT, the alpha particles emitted from the TNT cause electrons to move around inside the object. As a result, the object becomes hot. An EDS detects this heat and measures the amount of energy released.
In addition to detecting TNT, EDSs can also detect other substances used in making bombs. For example, EDSs can detect RDX, PETN, TATP, and C4. RDX is a plastic explosive that is often found in improvised explosive devices (IEDs) and car bombs. PETN is a nitrate ester explosive that is commonly used in homemade bombs. TATP is a high explosive compound that is used in many homemade bombs. And C4 is a military grade explosive that is often used in IEDs.
The best EDSs can detect explosives at concentrations as low as 0.01 milligrams per liter. That means that if you were to put a few drops of water into a bottle filled with TNT, the EDS would still be able to detect it.
Explosives Detection Systems (EDS) are used to detect trace amounts of explosives in luggage, cargo containers, vehicles, and buildings. These devices use ion mobility spectrometry technology to identify chemicals based on their unique electrical properties. Ion mobility spectrometers work by passing ions through a gas flow tube where they collide with electrons. When the ions pass through the tube, they cause a change in the electric field inside the tube. As the ions move through the tube, they interact with the molecules of the gas, causing them to vibrate. If the molecule has been exposed to a chemical that contains an explosive, the molecule will vibrate faster than normal. By measuring the speed of the vibration, the device can determine whether the substance is an explosive or not.
EDS systems are designed to detect trace amounts of explosive materials such as TNT, RDX, HMX, PETN, TATP, and C4. The system works best if there is at least one gram of explosive present in the sample. However, some manufacturers claim that their products can detect less than 0.1 grams of explosive.
If you want to know whether your home has been compromised by terrorists, you might consider purchasing a bomb detector. These devices are used by law enforcement agencies around the world to help them locate explosives. Some people use them to check their homes before going on vacation. Others use them to search for bombs after a terrorist attack.
The most common type of bomb detector is called a metal detector. Metal detectors work by using electromagnetic waves to determine if there is metallic material nearby. A person who wants to find a bomb must first remove his or her shoes and then walk across the floor where the device will be placed. Once the person walks across the floor, the device sends out electromagnetic waves which bounce off the ground and back to the device. The device then measures the amount of energy reflected back from the floor. If the amount of energy is greater than normal, the device alerts the user that something is present.
