Glossary · Hazards and harm
Radiation hazard
In machine safety, a radiation hazard is a hazard arising from ionizing radiation, such as X-rays, or non-ionizing radiation, such as laser light, ultraviolet, infrared or electromagnetic fields.

- Technical documentation
In one sentence
A radiation hazard on machinery comes from lasers, UV lamps, welding arcs, infrared heaters, electromagnetic fields or X-ray inspection systems.
Example
A laser cutting machine encloses the beam path completely; the access doors are interlocked so that the laser cannot emit while they are open.
How it applies
- Machine safety: Sources include lasers, welding arcs, UV curing lamps, infrared heaters, induction and RF heating, and X-ray inspection systems. Enclose the source, secure access with an interlocking guard and limit emission to what the process needs.
- Integrated systems: Radiation sources often come as bought-in components with their own classification and documentation. The integrator must assess the complete machine, including viewing windows and maintenance access.
- Technical documentation: State emission data where required, the eyewear or shielding needed for service tasks, and the specific safety signs. Separate laws on ionizing radiation may apply in addition to machinery law.
- Evidence: Keep component data, measurements and interlock verification in the technical file.
