Sources of Radon Exposure

• The only way to effectively determine the level of a person's exposure is to measure radon levels within the home. Several companies offer professional testing services, as well as do-it-yourself home testing kits. Of course, the level of radon exposure will greatly affect what, if any, symptoms are present. The U.S. surgeon general and the Environmental Protection Agency recommend that all homes be tested for radon levels regularly, and the EPA has established safe and acceptable radon level guidelines.
  
  

Absence of Symptoms

• Most doctors agree that radon exposure, at the level that most individuals would experience it, doesn't result in any noticeable symptoms in the short term. This is the reason radon testing is recommended. Radon gas is completely colorless, odorless and tasteless but can be present in any residence at levels that can result in long-term lung damage. Radon exposure is the second leading cause of lung cancer in the United States.
  
  

Severe Shortness of Breath

• Severe shortness of breath should always be evaluated by a health care professional, and should be of particular concern when it continues over a long period. In the case of radon exposure and possible lung cancer or pre-cancer, such shortness of breath can occur as a result of lung blockage or fluid buildup.
  
  

Hemoptysis and Coughing

• Hemoptysis is coughing up blood, and should always be considered serious. This symptom occurs in most people with lung cancer, although it can be caused by other conditions. Additionally, any severe cough that worsens over time, doesn't respond to treatment or seems to be chronic should be evaluated by a medical professional.
  
  

Paraneoplastic Symptoms

• Paraneoplastic symptoms are those that occur as an indirect result of cancer. These include such conditions as chronic, unexplained fatigue and weight loss, anemia, dizziness and muscle weakness and unexplained rashes. Particularly when these types of symptoms are seen in conjunction with others mentioned above, they warrant serious examination.
