The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States. H&J Freile offers two methods of testing for radon. A charcoal canister or passive test and a Continuous Radon Monitor (CRM) or active test. The CRM is a premium test that provides tamper detection circuitry and hourly recording of radon levels to improve reliability and confidence in the test results. The radon measurement with a CRM can be obtained in as little as 24 hours and is typically available in 72 hours. Based on house construction and conditions at the time of the test, a charcoal canister may be placed in the house along with the CRM for additional information. The charcoal canister test is a basic and economical test. Results from the charcoal canister test are typically available in 7 to 10 days. Radon in water testing is also available.

The State of New Jersey requires that any radon test performed for a real-estate transaction be conducted by a licensed radon measurement technician and evaluated by a licensed laboratory. This means that the test device must be placed and retrieved by a licensed technician. All H&J Freile home inspectors are licensed radon measurement technicians. In addition, H&J Freile has two full-time environmental technicians that are also licensed for radon measurement. Be wary of anyone who conducts a radon test and asks you, the homeowner or realtor to retrieve the measurement device. Not only will the test results be questionable; it is against the law.
