A good start would be the review articles listed here: https://scholar.google.com/scholar?q=rna+half-life&hl=en&as_.... If there's a paywall, use sci-hub or check the lab's page for a pdf. I should caveat that there is no one rna half life, some live much longer
It's ok if you don't have recommendations, but sending a google link is a bit out of pocket :(
Check out the review articles in the “Nature Reviews” journals, like “Nature Reviews Genetics”. These articles are written by experts but designed for a non-specialist audience (with undergraduate science education).
Ha! I'm sorry. not trying to be cagey/dismissive. There's no paper that must be read: they're all nodes in a network. All I can do is point you to a cluster, w/ the right filter and jargon search terms. Apologies if I came off out of pocket.
