Swakopmund:Field inspections, scientific sampling, and laboratory analysis are being tested during the Comprehensive Nuclear-Test-Ban Treaty Organisation's (CTBTO) Integrated Field Exercise (IFE). This exercise evaluates inspectors' ability to gather and assess evidence of a suspected nuclear test.

According to Namibia Press Agency , Namibian surrogate inspectors Samuel Nengola and Feruschka Himarua discussed the operation in an interview, explaining the simulation's role in testing their training, investigative techniques, and evidence-gathering methods before reaching any conclusions.

Surrogate inspectors are selected by their governments and receive specialized training based on their expertise. This is followed by regular training to maintain and update their skills. Nengola highlighted that inspectors undergo training for three to four years to prepare for deployment and evidence collection during on-site inspections.

Himarua, who has been in training since 2016, serves as the technical subject leader for visual observation. Her responsibilities include examining field sites for unusual features that may require further investigation. Inspectors utilize various techniques to evaluate geological and environmental characteristics, while laboratory teams collect and analyze soil and air samples for relevant evidence.

Himarua noted the challenges posed by the natural uranium in the area, which complicates the distinction between natural geological features and evidence that might necessitate further investigation. The terrain's ruggedness and ongoing mining activities further challenge the inspectors.

At the operation's base, teams returning from the field and their equipment are screened for possible contamination. A designated decontamination tent is available for additional checks if needed. Samples collected in the field are registered and analyzed by laboratory personnel, ensuring a chain of custody to maintain the evidence's integrity.
