Which document is essential to request from the client to ensure noninterference during radon testing?

Requesting a noninterference agreement from the client is essential to ensure that the radon testing process remains unimpeded. This document outlines the expectations regarding the testing environment and helps confirm that the client understands the importance of not interfering with the testing conditions. The purpose of the noninterference agreement is to minimize any potential influences that could affect radon level readings, such as ventilation changes, use of appliances, or alterations to the physical space being tested.

This agreement not only helps to maintain the integrity of the testing results but also provides a clear framework for the client regarding their responsibilities during the test period. By having this documentation, you ensure both compliance with industry standards and the reliability of the radon measurements taken.

While other documents like a test results summary, client consent form, and mitigation contract may serve different purposes in the context of radon testing, they do not directly address the specific need for minimizing interference during the actual measurement process as a noninterference agreement does.
