Iridium-192
A radioactive isotope commonly used as a radiation source in radiographic testing. Ir-192 has a half-life of 73.8 days and emits gamma rays suitable for radiography. It is preferred over cobalt-60 for thin-wall inspections and portable industrial radiography due to its higher density, allowing smaller source capsules. Ir-192 requires less shielding than Co-60 but more safety precautions than X-rays.

Equipment Selection and Use
Proper selection and maintenance of iridium-192 is critical for successful NDT inspections. Equipment must be calibrated and verified per applicable standards.
Maintenance and Verification
Regular maintenance and calibration verification ensure reliable equipment performance. Equipment that falls out of calibration can produce unreliable results.
Best Practices
- Always follow applicable NDT standards and procedures
- Use properly calibrated and maintained equipment
- Ensure personnel are properly trained and certified
- Document inspection procedures and results completely
- Keep current with industry standards and best practices
