Standards: DIN 4150-3, BS 7385-2, USBM RI 8507, and the local limit that actually applies.
Name the limit that applies here. Do not paste a table from a different country onto this neighbour.
Write the neighbour limit before the first hit.
Produce an artefact before you tick: a written note, a marked drawing, a cited figure, a filed hold. Watching is learning. The tick means applied.
Study notes. Not a certificate. Not legal advice. We never design the charge, spacing, or the cut. Follow the law and the named people where you work.
Before you tick
- Receptor named.
- Limit written.
- Instrument range known.
Write the neighbour limit before the first hit.
