As well as Environmental physics.
Would these topics be considered on topic here - specifically, I am looking at instrumentation for monitoring and evaluation, as well as, for example - a comparison of UVA and UVB energy on the human skin and eyes.
Possibly, it depends on the question. However, note that Biology.SE, Chemistry.SE, and the Sustainable Living SE exist too. Look at their respective help centers ("help" link up top, see the "What topics can I ask about here?" sections) and try to determine which site your question belongs on. If you end up asking on the wrong site, don't worry, it can be migrated (or improved to fit that site better).
I suggest you ask the question first and link to it in this post. Usually one deals with choosing the right site for interdisciplinary questions on a per-case basis. Note that some questions can be on topic for more than one site; in which case you can ask on either.
In this case, it looks like your question would be better on Biology.SE. It could be on topic here; but I doubt that you would get an answer.
