>the speaker should try and emphasize INorganic or say it in a clearer way

The root problem here is that while the speaker may have been an expert in handling nuclear materials, they were not ALSO an expert in communication. The failure was the presumption that an expert can clearly communicate their domain knowledge across an expertise gap. Communication is a skill unto itself, one that often gets handwaved. People just assume they're good communicators because they can assemble a grammatically correct sentence. My wife is an editor. If I had a nickel for every time she's come home with a story about yet another coworker who claimed they "already edited their own paper and it just needs a quick look-over" and then handed her an incomprehensible mess, I'd have a lot of nickels.
