2 Origins of SCAR SCAR = Small Controlled Area Radiography Techniques originally developed for offshore radiography IAEA* dose limits (0.75 / 0.25 mr/hr) Benefit: Up to 98% reduction exclusion zone when compared to conventional radiography techniques *International Atomic Energy Agency

3 Dose Rate Regulations USA & Asia 2 mr/hr Barricaded boundary 100 mr/hr Posted high radiation zone Canada 2.5 mr/hr Barricaded boundary IAEA* 0.75 mr/hr Controlled area; Rad workers only 0.25 mr/hr Supervised public exclusion zone *International Atomic Energy Agency

4 SCAR vs Conventional RT *For spatial reference only 4

5 Key Application Areas Congested or confined work areas Environments where RT inspections must not affect nuclear gauges and plant safety systems Nuclear sites with high background radiation
