Art. 93 Design

1 With re­gard to design, sealed ra­dio­act­ive sources must re­flect the state of the art when they are placed on the mar­ket.

2 For sealed ra­dio­act­ive sources, the ra­di­o­nuc­lides se­lec­ted must be chem­ic­ally as stable as pos­sible.

3 If sealed ra­dio­act­ive sources are used ex­clus­ively as gamma or neut­ron emit­ters, shield­ing must be provided which pre­vents the es­cape of al­pha or beta ra­di­ation.
