In the movie, “The Princess Bride,” the Man in Black describes his fictitious iocane powder, used in a deadly game, as being odorless, tasteless, dissolving instantly in liquid, and among the more deadly poisons known to man.

In this course, we will examine what we do know about this ubiquitous, ever-present, radioactive gas, why more and more, it tends to accumulate in our buildings, the danger that represents to the health of occupants and what exactly can be done to lower our increasing risk.
