Pipeline inspection apparatus

A pipeline inspection apparatus comprising:

• a first component housing section including a neutron source;
• a second component housing section coupled to the first component housing section and including one or more gamma ray sensors for measuring gamma rays;
• one or more support structures extending outward from each of the first and second component housing sections;
• the first component housing section, second component housing section, and support structures being cooperatively configured such that as the pipeline inspection apparatus moves through an interior of a pipeline:
• the support structures support the first component housing structure and the second component housing structure centrally within the pipeline;
• the first component housing section and the second component housing sections can articulate relative to each other as the pipeline inspection apparatus moves through curves in the pipeline;
• the neutron source can emit neutrons into regions surrounding the pipeline;
• and the one or more gamma ray sensors can measure gamma rays entering the pipeline from the regions surrounding the pipeline.
