• Aerial monitoring can be regarded as an

appropriate method for a rapid survey

• to provide information on large area display (computer)

video- GPS
surface contamination (ground camera

computer
contamination survey) or NaI(Tl)-detectors

HPGe-detector
• to search, detect localize and identify

gamma-emitting source(s) over large areas

in order to render the source safe

• For aerial surveys high HPGe detectors or Na(I)

detectors are the favorite detectors

• Systems based on pressurized ionization

chambers, proportional counters, GM

detectors or other suitable dose rate meters

may be also used
