Measuring Radon Levels in Basement Air

In this project, you'll measure radon levels in different locations of a basement. You'll analyze how changes in ventilation affect these readings.

Measuring Radon Levels in Basement Air

Hypothesis

If ventilation is increased in a basement, then the radon levels will decrease.

Step-by-Step Procedure

  1. 1

    Place radon detectors in five different locations in the basement.

  2. 2

    Record initial radon levels without any ventilation.

  3. 3

    Turn on the ventilation fan and increase air circulation.

  4. 4

    Measure radon levels at each location every 24 hours for a week.

  5. 5

    Record the data in your notebook.

  6. 6

    Compare the radon levels before and after ventilation.

  7. 7

    Analyze which areas show the most significant change.

  8. 8

    Graph the data to visualize the impact of ventilation.

Expected Results

You should observe a decrease in radon levels in areas with increased ventilation. Areas with poor ventilation might show higher readings.

Variables

Independent Variable

Ventilation

Dependent Variable

Radon levels

Controlled Variables

Basement location, Detector sensitivity, Measurement time

Safety Notes

Ensure adequate ventilation and wear a mask and gloves to avoid radon exposure.

Presentation Tips

  • Use graphs to show changes in radon levels.

  • Include photos of your setup.

  • Explain the health risks of radon exposure.

Frequently Asked Questions

Why is radon dangerous?

Radon is a radioactive gas that can cause lung cancer over prolonged exposure.

How does ventilation affect radon levels?

Increasing ventilation can help reduce radon levels by dispersing the gas.

What is a radon detector?

A radon detector measures the concentration of radon gas in the air.
