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
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
SCAR vs Conventional RT
4*For spatial reference only
Key Application Areas
Congested or confined work areasEnvironments where RT inspections
must not affect nuclear gauges and
plant safety systems
Nuclear sites with high background
radiation

SCAR = Small Controlled Area Radiography
Radiography in congested worksites using SCAR technique
• Source never fully unshielded → flash dose
• 3-9 ft. exclusion zones by controlling scatter and back-shielding the primary beam
Tungsten Collimator Shielding:
End – 25 HVL*
Radius– 30 HVL* (excluding beam
port)
*Half Value Layer
