An optical (black and white) picture of the measurement situation is taken before the gamma measurement starts. The CZT spectrum can also be used to run computer codes like MGA or MGAU for the determination of the isotopic composition of nuclear material. A CsI scintillation detector with less energy resolution but more efficiency is used when a short measuring time is required. A CZT room temperature semi conductor detector is used if high resolution is crucial. The gamma scanner is equipped with two different detectors. A gamma scan can locate the nuclear material in an object of unknown inner structure and thus help to identify its type, e.g., nuclear or radiological. A gamma scanner of type RoSCAN complements the abilities of the system. The container itself provides the necessary infrastructure, e.g., energy supply, communication means, and work places. No charger or special power supply is required, which means that the PREDATOR is ready when you are.Abstract For detection and identification of nuclear material we equipped a transportable container with neutron and gamma measurement systems. All the PREDATOR needs to operate are three, off-the-shelf, D-Cell batteries. The PREDATOR is built to withstand rugged use, can be used in all weather conditions, and will endure rigorous decontamination procedures.Īll radiation measurements are stored in non-volatile memory, so no measurement data will be lost, even when there is no power. The PREDATOR houses a built-in Bluetooth wireless data link that conveniently sends measurement results to a remote PC up to 300 feet away. Once an elevated radiation reading is detected, the PREDATOR can provide a true dose rate reading and then identify the isotope. In addition to material identification, the PREDATOR is also a very sensitive radiation detector allowing public safety personnel to sweep large numbers of people, packages, or vehicles to quickly detect gamma contamination or locate loose radiation sources. This powerful instrument uses a combination of up to four different detectors to identify 107 different radioactive materials including, Medical Isotopes, Industrial Isotopes, and Special Nuclear Materials. Identifying a radiation source simply requires pressing a single button. The PREDATOR-Series is an isotope identifier that is easy to use with almost no training.
