ROI Calculation Logic

Conventional radioactivity evaluation requires approximately 2,000 hours of expert analysis annually (10 experts × 16 hours/month × 12 months), incurring an estimated annual labor cost of ~$1.35M (AI est.). By reducing this workload by 10-15%, this technology could save ~2,000 hours × 10% × $83.50/hour (AI est.) = ~$167K/year (AI est.). Additional benefits from improved evaluation accuracy, such as reduced re-evaluation costs and risk avoidance, are also possible.
