Nice! I like this idea and look forward to seeing it develop further.

A bug to report: inspired by comments elsewhere in this thread, I searched for "radiation", and your interface is rendering the bulleted list about different kinds of radiation above the actual first paragraph (which ends with "This includes:" to introduce the list).

Yes, noted, thanks. Some wikipedia templates are difficult to get right. Will see how to fix this and make the presentation clearer.
