Terms of use

Last updated 19 October 2026

These terms apply to anyone reading or searching this site. The short version: the index is a reading aid built from published sources, supplied as it is, and the decisions you make from it are yours.

What the index is

tracer.nuclear is an index compiled from published literature and open registers. Every value links back to the source it was taken from. How it is built explains what is included and what an empty field means.

Supplied as it is

We give no guarantee that the index is complete, accurate or up to date. Extraction from papers is partly automated, and it misreads things. A record can be wrong, out of date or missing.

What it is not

It is not a clinical recommendation. It does not replace a pharmacopoeial monograph, a marketing authorisation or the guidance of your regulator. It is not a basis for releasing a product to patients.

Yields, injected activities, uptake times, purities and similar values are given as published. They are not a specification. Values from different groups were measured under different conditions and are not directly comparable.

Responsibility

Decisions made on the basis of this data are the user's. Check anything that matters against the primary source, which every value links to, and against the current official text. To the extent the law allows, we are not liable for loss that comes from using the index. Nothing here limits liability that cannot be limited by law.

Using the site

You can read, search and link to any page. How the data may be reused is on the licence page. Do not present the index as your own work, and do not put anything unlawful into the enquiry form.

Other people's content and links

Publications, registers, monographs and structure records belong to their owners and are listed on the licence page. We link to external sites and are not responsible for what they contain.

Services

The services page describes what we offer. An enquiry does not create a contract. Supply of equipment or consumables is agreed separately, in writing.

Errors and changes

If you find an error, see corrections and takedown. We may change these terms; the date at the top shows when.
