Eligibility Criteria

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may not qualify if:

  • Not residing at the household for at least 5 days a week or family planning to move from the current home within the next twelve months, or homes with active radon mitigation systems (if home uses a HEPA filter air purifier, family must agree to disable the purifier for 28 days prior to randomization).
  • Lung disease, other than asthma, that requires daily medication (inflammatory diseases, chronic lung diseases aside from asthma, congenital cardiopulmonary conditions requiring medication or surgical treatment),
  • Homes with active HEPA filters will be excluded (even though the role of HEPA filters on radon and radon particles s is expected to be minimum and other exposures can be adjust for in the analysis)
  • Cardiovascular disease that requires daily medication, excluding hypertension
  • Taking a beta-blocker
  • Currently receiving unstable level of Immunotherapy (allergy shots)
  • Coordinator/PI judgment
  • Inability to perform lung function testing
  • Intake of abuse drugs or alcohol, have psychiatric disorders or severe mental disability that interferes with answering questions or following instructions.
