1075 SCARProSENTINELTM – QSA Global Inc.

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
