NEHA Housing Sanitation & Safety Practice Exam 2025 - Free Health & Safety Practice Questions and Study Guide

The purpose of a radon test in housing is to determine the levels of radon gas present. Radon is a colorless, odorless radioactive gas that can seep into homes from the ground, particularly in certain geographical areas. It is a health hazard because prolonged exposure to elevated levels of radon is associated with an increased risk of lung cancer. Testing for radon is crucial as it allows homeowners to identify whether their living space has unsafe levels of this gas, enabling them to take appropriate remedial actions if necessary.

The other choices do not pertain to the specific focus of a radon test. Humidity levels are assessed through different means, structural integrity evaluations use various inspection methods, and thermal comfort evaluations consider temperature and air quality rather than radon levels. The targeted focus of the radon test on gas measurement is essential for ensuring the safety and health of the occupants in a dwelling.
