Answer 1

When conducting a short-term radon measurement, it is important to close any openings to the outside, including combustion air and bathroom exhaust fans.

Step-by-step explanation:

When conducting a short-term radon measurement, it is important to close any openings to the outside, including combustion air and bathroom exhaust fans. This is because radon gas can easily enter buildings through these openings, leading to increased exposure. By closing these openings, you can ensure that the measurements accurately reflect the indoor radon levels.
