## Abstract Porphobilinogen‐11‐^13^C was prepared by using benzyl 3‐(β‐methoxycarbonylethyl)‐4‐ (methoxycarbonylmethyl)‐2‐pyrrolecarboxylate as a starting material. A Vilsmeier‐Haak formylation with N,N′‐dimethylform‐^13^C‐amide gave the 2‐formylpyrrole, which was transformed into its oxime, and th

✦ Synopsis
The cornerstone of release criteria are dose limits for the public and dose constraints for relatives and caregivers. In spite of this, there is wide variation in criteria used to decide whether to release or hospitalise patients. At present, the two general forms of release criteria are those based on individual situations and projected doses to other people, and those based on retained activity (usually following conservative assumptions). Since lifestyle habits differ between and even within countries, a single model for release criteria would not be appropriate optimisation. It is recommended that release of patients should be based on their family situation (rather than retained activity and the worst-case scenario). It is also recommended that when there are many contiguous countries, a uniform or similar approach to releasing patients should be developed.
