This course is designed to teach industry-accepted methods of inspecting and testing homes for radon using national standards of practice. Your journey begins with a thorough discussion of radon gas, its decay products, and a history of its discovery, its prevalence, and the health effects associated with exposure. You will then learn about testing methodologies, how to perform a test for radon, how to perform a visual inspection for conditions that are favorable for radon entry, and how to complete a professional radon inspection report. You will also be exposed to techniques for reducing radon levels, known as mitigation. In addition to technical skills, this course provides practical guidance for informing your clients of the presence of radon, along with other recommendations to ensure your testing and reporting achieves the highest standards of professionalism and accuracy.
