Detailed Overview

The GAMCPR Close Proximity Radiography (CPR) System is a dedicated accessory kit and technique specifically for the Exertus Selen Circa gamma ray projector. It is used to enable safe gamma radiography in confined or active production areas. The system employs tungsten collimation and flexible shielding mats to tightly focus the radiation beam and absorb scattered radiation thereby drastically reducing the required radiation exclusion zone (often less than 3-meter radius), ensuring high-quality images while minimizing disruption to surrounding work.

A specialized system for achieving high-quality gamma radiography 24/7 with drastically reduced safety distances.

• It is designed to achieve the principle of ALARA (As Low As Reasonably Achievable) in industrial radiography.

Top Features & Benefits

• Radiography in Close Proximity to other site operations and radiation sensitive monitoring devices.
• Achieves exclusion zones of less than 3m depending on source strength.
• Tungsten Directional Collimators for precise beam focusing.
• Flexible Bismuth Shielding Mats and shielded guide tubes to minimize scattered radiation.
• Improves productivity by enabling radiography during normal plant operations.
• Versatile application, adaptable for both contact and ellipse shots.

Primary Uses & Functions

CPR is achieved by utilizing a system of X-ray or Gamma emitting devices incorporating specific collimation with rigid and / or flexible shielding to reduce the Primary Beam and scattered radiation to safe levels at the desired barrier distance.

Real-World Applications

• RT inspection of welding in refineries, power plants, and chemical facilities without stopping nearby work.
• Enabling 24/7 RT inspection during facility outages and turnarounds in confined, complex areas.

Industry Solutions

• Oil & Gas (On-stream pipeline and vessel inspection)
• Chemical (Process pipe and plant integrity)
• Power Generation (Outage and boiler inspection)
• General Manufacturing (Radiography bays / laydown areas)

Technical Specifications

Compatibility

• Works specifically with the Exertus Selen Circa gamma ray projector series (Circa 40/80/120) and  Selenium-75 (Se-75) sources.
• The shielding mats can also be used with Iridium-192 (Ir-192) sources to reduce primary beam intensity.
• Compatible with standard NDT film or digital detectors (DR/CR).

What’s In The Box?

• Specialized Tungsten Directional Collimator (Snap-On type).
• Tungsten shielded guide tube.
• Flexible Bismuth Shielding Mats.
• Clamping Jigs, Mounting Bases, and Support Legs for positioning.
• Primary Beam Shielding Cassette and Lead Sheets.
