The air in some caves includes a significant amount of radon gas, which can lead to lung cancer if breathed over a prolonged time. The air in one British cave has an activity per volume of 1.16 x 10³ Bq/m³. Suppose that you spend two full days exploring(and sleeping in) that cave. How many 222Rn atoms would you take in and out of your lungs during your two-day stay? The radionuclide 222Rn in radon gas has a half-life of 3.82 days. Take your lung capacity to be 1.6 x 10 m³ and your breathing rate tobe 37 breaths/min.NumberUnits
