Symptoms to Watch For
If you or your family members are experiencing any of these, radon gas could be the cause:
Your Children Breathe 20,000 Liters of This Air Every Day
Kids breathe more air per pound of body weight than adults. Their lungs are still developing. If radon gas is in your home, they're getting a higher dose than you are. You childproof cabinets and plug outlets — but have you checked what they're breathing?
⚠️ The EPA estimates indoor air can be 2–5× more polluted than outdoor air. Your family breathes 20,000 liters of indoor air every day.
If radon gas is present, every breath could be doing damage you can't see or feel — until it's too late.
