What is Radon? | Rhino Metrics KC Radon Testing

Radon 101

Radon is a colorless, odorless gas produced by the natural breakdown of uranium in soil, rock, and water.

Prolonged exposure to high radon levels increases the risk of lung cancer. It's important to monitor exposure to radon to help lower your risk.

Radon kills 21,000

people every year

HEALTH RISKS

When radon breaks down in the air, it creates tiny radioactive particles called radon progeny. These particles can lodge in the lungs, releasing radiation that damages cells and increases the risk of lung cancer.

The danger comes from elevated levels or long-term exposure, which is why ongoing monitoring is essential to understanding your risk. Learn more about your radon levels today.

The rocks and soil beneath our homes naturally contain uranium. As uranium breaks down through a process called radioactive decay, it produces radon gas.

When radon itself decays, it releases alpha particles, which are tiny bursts of radiation made up of two protons and two neutrons.

Radon progeny can attach to dust and other particles in the air, which are then inhaled into the lungs. As these particles break down, they release radiation that can damage the DNA within our cells.

DNA acts like an instruction manual for how cells replicate. When an alpha particle strikes DNA, it can break this blueprint. While cells are always making copies of themselves, a damaged blueprint can cause errors in the replication process, often leading to cancer.

Modern homes are built to be energy-efficient with tight insulation, but limited airflow can also let radon accumulate to dangerous levels over time.

The good news is that ventilation (even something as simple as opening a window) can reduce radon and keep indoor air safe. With long-term monitoring, you’ll know exactly when levels start to rise so you can take action before it becomes a risk.

Man-Made Problem?

Radon levels are usually much higher indoors than outdoors. The gas seeps up from the ground and gets trapped inside our homes, creating concentrations rarely found in nature.

Does the weather affect Radon?

Yes! Wind, rain, and humidity levels can strongly affect radon levels. Especially as the outside conditions affect how we adjust our indoor comfort with HVAC systems, too.

How does it enter my home?

Radon rises through the soil and enters through cracks in the foundation and entry points made my pipes, drains, and ducts.

Do levels ever change?

Radon levels do flucuate over time. Levels change with the season, renovations, geography, earthquakes, humidity, temperature, and ventiliation.

Does it affect the top floors?

Radon levels can still be high on the top level due to the stack effect, artificial ventilation, and even building materials.

Who is sensitive to radon?

1 in 30 are fundemantally sensitive. Children and those who smoke are the most sensitive.

What do my radon levels mean?

Good

0.0 pCi/L - 1.9 pCi/L

expirement with ventilation and sealing cracks to lower levels.

Fair

2.0 pCi/L - 4.0 pCi/L

continue monitoring and consider mitigation.

Poor

4.0 pCi/L and above

install an active mitigation system and continue monitoring
