Optimal radiographic results and site safety depend on balancing several key factors related to the chosen isotope source and the material being inspected.
Higher activity shortens the required exposure time but increases the required safety distance.
Heavier alloys or thicker sections require either a longer exposure time or a stronger source.
Smaller focal spots enhance image resolution but may require longer exposure times.
What paperwork do I need to submit?
Required documentation often includes:
- Export Permit
- Authorization to ship Radioactive material (when sending projectors to South Africa for loading)
- Purchase Order and/or Payment confirmation
- Permit/license to use, possess and convey Radioactive material
- Permit/license to Import Radioactive material
How does half-life work?
The half-life is the time required for one half (50%) of the unstable material to degrade into a more stable material.
Example: A 100 Ci source reduces to 50 Ci after one half-life. Ir-192 has a half-life of about 74 days; Se-75 is about 120 days.
