Page 4: General
1 General 1.1 Designation and Application Range 1.1.1 BDAB is designed to: - measure - radiation flux density; - measure β- radiation flux density; - search for - β- sources. BDAB provides programming of the operation modes. BDAB can be used by emergency, customs, frontier, and other service staff. The instruments are used by radiological and isotope tracing laboratories and customs officers to identify radionuclide matter compositions, measure gamma radiation DER, search ionization sources to prevent the illicit trafficking of radioactive materials. -
