I understand—and I don't know, so correct me if I'm wrong—that the radon gas we get at home would probably have different levels of radioactivity. How does this unit refer to the level of radioactivity in a gas? As I understand it, it's not only the level of the gas itself, but there's also the time of exposure. I would assume that the level of radioactivity plays a very important role here as well.
