Radon: The Invisible Lung Risk in Your Basement

By The Breathizen Team · Published · Reviewed September 22, 2026

You cannot see, smell or taste radon, and it causes no immediate symptoms. The only way to know your level is to test, which costs about the same as a takeaway meal.

Quick answer: Radon is a radioactive gas that seeps from the ground into buildings. It is the second leading cause of lung cancer after smoking. Testing is cheap, and high levels can be fixed with a vent system.

The bigger picture

Air quality is the part of respiratory wellness you can engineer. You cannot change your age or your genes, but you can change what you breathe at home and at work. Attention to radon at home pays off every hour of every day, quietly, which is more than can be said for almost any product.

Where radon comes from

Uranium in soil and rock decays into radon gas, which moves up through cracks and gaps in foundations. Levels vary house to house, even between neighbours, and are usually highest in basements and ground floors.

How to test

Short-term kits sit for a few days and are mailed to a lab. Long-term kits measure over ninety days for a better average. The EPA action level is 4 picocuries per litre, and it suggests considering fixes above 2.

Fixing a high reading

A certified contractor installs a pipe and fan that draws gas from beneath the slab and vents it above the roof. Most systems bring levels down dramatically within a day.

Practical tips you can use today

  • Test every home, new or old.
  • Retest after major renovations.
  • Smokers face a multiplied risk from radon.
  • Ask for radon results when buying a house.

Common mistakes to avoid

  • Assuming indoor air is clean because it looks clean.
  • Buying a purifier too small for the room.
  • Masking odours with fragrance instead of ventilating.
  • Forgetting filter changes until airflow drops.

Where Breathizen fits

If you arrived here researching radon at home, you are already doing the most useful thing, which is paying attention to your breathing. Breathizen can be one part of that attention. Each bottle holds about 100 small servings of a mullein, ginger and lemon blend. It is swallowed, not inhaled, and it is never a substitute for an inhaler, a prescription or a conversation with your doctor.

What you would see if you turned our bottle around: directions to shake well and take the serving by mouth; a caution for pregnant or nursing women and anyone under 18; a note to consult a physician if you have a medical condition; and a 154 mg blend of mullein, ginger and lemon. Dietary supplements are not FDA approved, and ours makes no such claim. You can read more about Breathizen ingredients and Breathizen reviews on the Breathizen site.

When to see a doctor

Cleaner air helps everyone, but symptoms still need proper assessment. If you have a cough, wheeze or chest tightness that persists after improving your home's air, or symptoms that ease on holiday and return at home or work, tell your doctor about that pattern. Sudden breathlessness, chest pain or coughing blood need urgent care.

Key takeaways on radon at home

  • Radon is a radioactive gas that seeps from the ground into buildings.
  • Where radon comes from: the basics matter most.
  • Fixing a high reading is where small daily actions pay off.
  • Supplements such as Breathizen are optional extras, never substitutes for medical care.

Frequently asked questions

Do air purifiers really work?

True HEPA purifiers sized for the room reduce airborne particles substantially. They do not remove gases without a carbon filter.

Are scented candles bad for indoor air?

They add fine particles and volatile compounds. Occasional use with ventilation is a small exposure; daily use in closed rooms adds up.

Is Breathizen inhaled?

No. It is a liquid taken by mouth and swallowed. It is not an inhaler or a medicine.
