Why switch from film to digital radiography in NDT?
Digital radiography enables faster inspections, better image quality, lower operational costs, improved safety, and fully digital workflows. It helps NDT professionals increase efficiency, reduce costs, and modernize inspection processes.

Introduction
Film radiography has long been the standard in non-destructive testing (NDT). Today, however, digital radiography (DR and CR) is becoming the new industry benchmark, offering major improvements in performance, efficiency, and workflow integration.
Here are 5 key reasons why more companies are making the switch.
1. Faster inspections and real-time results
Film-based radiography requires chemical processing and waiting time.
With digital radiography:
- images are available instantly
- results can be validated immediately on site
Benefit: faster inspections, increased productivity, and reduced downtime.

2. Enhanced image quality with advanced software
Digital radiography offers greater flexibility in image analysis:
- contrast and brightness adjustment
- zoom and filtering
- improved defect visibility
With our digital radiography software, Sherlock NDT, inspectors can:
- process images in real time
- apply advanced analysis tools
- improve reporting and traceability
Benefit: more accurate inspections and fewer retakes.

3. Lower operational costs
Film radiography involves recurring costs:
- consumables (film, chemicals)
- storage and handling
- longer inspection cycles
Digital radiography significantly reduces these costs.
Benefit: lower cost per inspection and faster return on investment.
Market insight: Rising film costs
Radiographic film is becoming increasingly expensive due to rising raw material costs, especially silver, as well as supply and production constraints.
Manufacturers have already announced price increases, making film-based inspections more expensive year after year.
As a result, switching to digital radiography is not only a performance upgrade, but also a way to better control long-term costs.
4. Safer and more sustainable inspections
Digital solutions reduce:
- radiation exposure
- chemical waste
- environmental impact
Benefit: improved safety and easier compliance with health, safety, and environmental (HSE) regulations, thanks to reduced radiation exposure and elimination of chemical processing.
5. Fully digital workflows and data-driven inspection
Digital radiography enables a fully connected workflow:
- digital storage of images
- instant sharing with teams or clients
- integration into reporting and maintenance systems
Benefit: better traceability, faster decision-making, and alignment with Industry 4.0.
Real-world example: How KAEFER Australia reduced costs with digital radiography
KAEFER Australia replaced invasive CUI inspections, requiring insulation removal, with digital radiography.
This allowed them to:
- eliminate insulation removal
- reduce inspection time
- significantly lower operational costs

Conclusion
Switching from film to digital radiography is no longer just a technical improvement, it is a strategic decision.
✔ Faster
✔ More accurate
✔ More cost-efficient
✔ Safer
✔ Data-driven
And with film costs continuing to rise, the transition is only accelerating.
