Radon & Children
Protecting your family from an invisible threat
Evidence-based information about radon risks in children and how to keep your family safe
Why Children Are Especially Vulnerable to Radon
Multiple biological and developmental factors make children more susceptible to radon's harmful effects
Rapid Cell Division
Children's cells divide more rapidly than adults, making them more susceptible to radiation-induced DNA damage. This increased cellular activity means radon particles can cause proportionally more harm during critical developmental years.
Faster Breathing Rate
Children breathe 20-30 times per minute compared to adults' 12-20 breaths per minute. This faster respiratory rate means children inhale significantly more radon particles per hour relative to their body size.
More Time at Home
Children spend 80-90% of their time indoors—at home, daycare, and school. This extended indoor exposure, especially during developmental years, significantly increases cumulative radon exposure compared to adults.
Developing Lungs
Children's lungs are still developing until age 18-20. Radon exposure during these critical growth years can cause permanent cellular changes that may lead to lung cancer decades later, even after minimal childhood exposure.
Age-Specific Radon Risks
Understanding how radon affects children at different developmental stages
Infants & Toddlers (0-3 years)
Most vulnerable due to rapid development and time spent in cribs/play areas near floor level
- Sleep 12-16 hours daily at floor level where radon concentrates
- Immune systems and lungs in earliest development stages
- Higher breathing rate relative to body size
- Cannot communicate symptoms or discomfort
Young Children (4-8 years)
Highly active with significant time spent playing on floors and in basements
- Play close to ground where radon levels are highest
- Spend extensive time in basements/lower levels
- Lungs still developing critical alveolar structures
- May not report respiratory symptoms
Pre-Teens & Teens (9-18 years)
Continued lung development with cumulative exposure concerns
- Bedrooms often in basements or lower levels
- Lung tissue still developing until early 20s
- Cumulative exposure from childhood compounds risk
- May spend time in basement recreation rooms
Critical Years for Protection
The first 15 years of life are the most critical for radon protection. Even short-term exposure during these developmental years can have lifelong health consequences. Testing and mitigating your home before children arrive or when they're young provides the most significant protective benefit.
Health Risks from Radon Exposure in Children
Understanding the serious health consequences of radon exposure during childhood
Lung Cancer
CriticalRadon is the #2 cause of lung cancer after smoking. Children exposed to radon have a lifetime elevated risk, with studies showing that exposure during developmental years increases cancer risk by 10-15% per 100 Bq/m³ increase.
Respiratory Issues
HighChronic exposure can lead to persistent coughing, wheezing, and increased susceptibility to respiratory infections. Children in high-radon homes show higher rates of asthma and bronchitis.
Immune System Impact
ModerateRadiation exposure from radon may compromise developing immune systems, potentially making children more vulnerable to infections and illnesses during crucial growth periods.
Long-Term Developmental Effects
ModerateEmerging research suggests chronic radon exposure during childhood may affect long-term lung function and respiratory capacity, potentially impacting athletic performance and quality of life.
Warning Signs in Children
Symptoms that may indicate radon-related health issues
Early Respiratory Symptoms
- Persistent cough lasting more than 3 weeks
- Frequent respiratory infections (more than 6 per year)
- Shortness of breath during normal activities
- Wheezing or whistling sounds when breathing
Behavioral & Energy Changes
- Decreased energy or unusual fatigue
- Reluctance to participate in physical activities
- Difficulty keeping up with peers during play
- Complaints of chest discomfort or tightness
Chronic Symptoms Requiring Medical Attention
- Persistent chest pain
- Coughing up blood (immediate medical attention)
- Severe difficulty breathing
- Unexplained weight loss
Important Medical Note: These symptoms can indicate various conditions, not just radon exposure. Always consult your pediatrician for proper diagnosis. If you live in a high-radon home and your child shows persistent respiratory symptoms, inform your doctor about potential radon exposure.
Scientific Research & Evidence
Peer-reviewed studies documenting radon's impact on children's health
Childhood Exposure & Lifetime Risk
A comprehensive study published in the British Journal of Cancer found that children exposed to residential radon during their first 15 years of life had significantly elevated lifetime lung cancer risk, with effects persisting even after moving to low-radon areas.
British Journal of Cancer, 2014
School Radon Levels
EPA studies found that 1 in 5 schools across the United States has at least one room with elevated radon levels, exposing children for 6-8 hours daily. The EPA recommends testing all schools below the third floor.
U.S. EPA School Study, 2019
Developmental Vulnerability
Research from the National Cancer Institute confirms that cells dividing rapidly during childhood and adolescence are particularly vulnerable to radiation-induced mutations, making radon exposure during these years especially dangerous.

How to Protect Your Children from Radon
Evidence-based strategies to safeguard your family's health
Test Your Home
Test all levels of your home, especially children's bedrooms, playrooms, and basements. If levels exceed 4.0 pCi/L (EPA action level), professional mitigation is essential to protect your family.
Elevate Sleeping & Play Areas
Place cribs, beds, and play areas on upper floors when possible. Radon concentrations decrease significantly with height—second floors typically have 50-70% lower levels than basements.
Professional Mitigation
Install a professionally-designed radon mitigation system. Sub-slab depressurization systems reduce radon by 90-99% and provide long-term protection throughout childhood and beyond.
Test Schools & Daycares
Ask about radon testing at your child's school and daycare. If facilities haven't been tested, advocate for testing—children spend 1,000+ hours annually in these environments.
