What are the methods of CBR surveys?

The methods of CBR (Chemical, Biological, Radiological) surveys include both ground and aerial techniques. Ground surveys typically involve the use of personnel and equipment to directly assess and sample the environment for hazardous materials. This may include using handheld detectors, sampling soil and air, and examining potentially contaminated surfaces. Aerial surveys leverage aircraft or drones equipped with detection technology to scan larger areas quickly, which can be particularly effective in identifying contamination over broader geographic expanses or reaching difficult terrains.

Combining both ground and aerial methods provides a comprehensive approach to CBR surveys. Ground surveys can provide detailed information at specific points, while aerial surveys allow for rapid assessment and the ability to monitor changes across larger areas.

In contrast, options that suggest only one method (like chemical and radiological only) or pair methods less relevant to the context are narrower in scope and do not cover the full range of techniques used in CBR survey operations. For effective CBR assessment, employing a dual-method approach enhances detection capabilities and improves response strategies.
