How can radon enter a home?

1. As with mould, tends to thrive in damp areas of a building.

2. Is most concentrated in the upper levels of a house.

3. Can enter a home through cracks in the basement floor and walls.

4. Is associated with the flow of electricity.

5. Can permeate through windows and doors.

6. Travels through sewer systems to enter a home.

The correct answer is: Can enter a home through cracks in the basement floor and walls.

Radon can enter a home through cracks in the basement floor and walls. Radon is a radioactive gas that is naturally present in the soil and can seep into buildings through cracks and openings in the foundation. It is important for homeowners to seal these entry points to prevent radon from entering the home and becoming trapped at high levels, which can pose serious health risks. The other options are not correct as they do not explain how radon specifically enters a home.
