Radon Testing in Seattle WA

Radon is a naturally occurring radioactive gas that can accumulate inside buildings. Because radon is colorless and odorless, testing is the only reliable way to determine whether radon levels are elevated in a property.

Radon gas can enter buildings through foundation cracks, crawlspaces, or other openings in the structure. Professional radon testing helps evaluate indoor radon levels and determine whether elevated concentrations may be present.

5 Microns Inc. provides professional radon testing services in Seattle for residential and commercial properties.

What Is Radon Gas?

Radon forms naturally from the breakdown of uranium in soil and rock. As the gas moves through the soil, it may enter buildings through openings in foundations and building materials.

Common radon entry points include:

  • Foundation cracks

  • Crawlspaces

  • Gaps around plumbing pipes

  • Sump pits

  • Floor drains

  • Construction joints

Because radon gas cannot be detected by smell or sight, testing is required to measure indoor levels.

Why Radon Testing Is Recommended

Radon levels can vary significantly from one building to another depending on soil conditions and building construction.

Radon testing is often recommended:

  • When purchasing a home

  • During real estate transactions

  • For long-term indoor air quality evaluation

  • In homes with basements or crawlspaces

Testing helps determine whether radon gas concentrations may be elevated inside a property.

Short-Term Radon Testing
