We used electrostatically-charged balloons to accumulate radon progeny from the air (Getty Images).

Investigating radiation in the air we breathe

Radon is a significant component of background radiation and can accumulate in poorly ventilated indoor environments. 

In this data set, we investigated the effect of electrostatically charging a balloon, which was then hung in an enclosed space, on its level of radioactivity. 

Students write a hypothesis, graph data, write a conclusion and use provided information to answer questions about radioactivity and radon, experimental design, accuracy, validity and reliability.
