Consistent, Defensible In Vivo Measurement for Nuclear Operations

Workers in hard hats writing on clipboard

Nuclear facilities require fast, accurate and defensible internal dose assessment to protect workers, maintain controlled access and demonstrate regulatory compliance — particularly during outages or periods of increased demand for whole-body counting. During these periods, rising demand, staffing constraints and variability in execution can create workflow bottlenecks – slowing personnel flow, introducing operational inconsistency and increasing audit exposure under pressure.

A structured in vivo measurement process supports consistent, efficient execution from whole-body counting through reporting.

• Repeatable whole-body counting workflows • Standardized analysis • Controlled reporting

Common Workflow Challenges During Periods of Increased Demand

During outages or periods of increased demand, whole-body counting workflows are often constrained not by system capability, but by the level of manual interaction and operator time required.

  • Bottlenecks in whole-body counting workflows that slow personnel flow
  • Variability in execution across operators and shifts
  • High dependency on manual interaction and operator intervention
  • Increased workload pressure on health physics staff
  • Delays that impact workforce efficiency and increase operational costs
