Can you die from radon gas?

Yes, you can. It's a very radioactive gas. Over 40,000 people in US and Europe die yearly from lung cancer caused by radon gas. But it's not like in those horror movies where your body melts away. It does not kill you instantly.

You can't see, smell or taste radon gas. And because of that, many people live in houses full of radon without being aware of it. You should do a radon test (link under "Sources and related links" below this answer) to find out if there's radon in your house. Amazon also sells radon test kits, and you should also check in your local area.yes
