DIY Radon Test Kit vs. Professional Radon Testing

Radon is a radioactive gas that is produced by uranium decay in soil, groundwater and rocks. When it is released outside, it disperses in the air, safely. But when it is released inside your home, it can lead to elevated and dangerous levels that can majorly harm your health. In the indoor environment of your home, it is released from the dirt and rocks beneath your home.

Not every home has elevated radon levels, but every one in fifteen homes does. There is no way to be sure that your home is (or isn’t) affected by radon as it is a tasteless, colorless, and odorless gas. However, if your home has 4.0 pCi/L, then you need to perform radon mitigation.

Most homeowners think that they can perform DIY radon tests, but for this, you should know the pros and cons of the process.

In this blog, we will break down a comparison between DIY vs professional radon testing. This will help you make informed decisions on your own.

DIY Radon Test Kits

To perform a DIY radon test, you need to get a radon test kit first. You can buy these from any hardware or home improvement store. In fact, you can also find them online. If you want a free test kit, then they’re sometimes available from the county or local health departments, or you can find these from state radon programs.

The test kits are devices that you can use to measure radon gas levels in particular locations of your home. The kit usually comes in the form of a passive device that absorbs radon from the air over a period of time. Two examples of such devices are alpha-track detectors and charcoal canisters. You shall place these kits in different areas within your home. It’s best to put these in the lowest livable area for a specific duration, typically for a few days to several months. This duration varies depending on the type of kit you will be using.

When the testing period is completed, you may send the kit to the laboratory for analysis, where the collected radon levels are measured. Once you have the results, you can then determine the radon mitigation measures to reduce radon levels and minimize the imposed risks.

Pros of DIY Radon Test Kits

Cost Effectiveness

DIY radon test kits are usually inexpensive compared to hiring a professional to carry out radon testing. This is why these kits are more accessible to homeowners who are on a budget.  

Ease of Use

Many radon test kits are designed to be user-friendly, with clear instructions provided. So, if you wish to conduct a DIY radon test, then you can follow the instructions given with the kits and perform the test on your own.  

Quick Results

Depending on the type of kit you’re using, DIY radon tests can provide you with relatively quick results. This will allow you to take prompt action if the test detects elevated radon levels.

Cons of DIY Radon Test Kits

Accuracy Concerns

DIY radon test kits may not always provide accurate results if they are not used correctly or if environmental factors interfere with the testing process. Improper placement of the test device or failure to follow instructions precisely could lead to inaccurate readings.

Limited Expertise

You may lack the expertise and experience of professional radon testers. Without proper training, you may not recognize potential issues that could affect the accuracy of the test results, such as interference from ventilation systems or other factors.

Quality Control

The quality of DIY radon test kits can vary, and some may be less reliable than others. Choosing a reputable brand and ensuring that the kit is certified by relevant authorities can help mitigate this risk, but there is still a possibility of not great performance.

Professional Radon Testing

Professional radon testing is a more thorough and reliable way of testing for radon. These tests are typically conducted using specialized equipment designed to measure radon levels accurately. The process of professional testing often involves placing continuous radon monitors or passive radon detectors in strategic locations within the property. Continuous monitors provide real-time data on radon levels, while passive detectors collect radon over a specified period, usually several days to several months. Professionals ensure that the testing devices are placed correctly and remain undisturbed throughout the testing period to obtain reliable results.

The duration of a professional radon test can vary depending on the testing method used and the specific circumstances of the property. Continuous radon monitors typically provide results within a few days, as they continuously measure radon levels over the testing period. Whereas, passive radon detectors may require several days to several months to collect sufficient data for analysis. The duration of the test is determined based on factors such as:

  • The type of detector used
  • The size of the property
  • The desired level of accuracy

The cost of a professional radon test can also vary depending on these factors. On average, a professional radon test may cost anywhere from $100 to $300 or more. Let’s break down the pros and cons of these tests below.

Pros of Professional Radon Tests


Professional radon testers have the training and experience to ensure an accurate testing process. They know how to properly place testing devices, interpret results, and account for potential factors that could affect accuracy.


With professional testing, you can have confidence in the accuracy of the results. Professionals use calibrated equipment and follow standardized testing protocols to get reliable measurements of radon levels in the property.

Comprehensive Analysis

Professional radon tests often include a thorough analysis of the results, along with recommendations for any necessary mitigation measures. This comprehensive approach ensures that homeowners receive detailed information about radon levels and guidance on how to address any issues.

Cons of Professional Radon Testing


The biggest con of a professional radon test is cost. It can be more expensive than DIY options. For this, you may need to allocate a larger budget to cover the cost of hiring a professional tester, especially if you’ve included additional services such as mitigation consultation.

Scheduling Constraints

Coordinating with a professional tester may require scheduling appointments and accommodating their availability, which could be challenging for you if you often have busy schedules or time constraints.

Limited Control

You may have less control over the testing process when relying on a professional tester. You are expected to trust the tester to follow proper procedures and accurately interpret results without being directly involved in the testing process themselves.


If you are deciding between professional radon testing and DIY test kits, then you need to cater to different factors. These may include budget, convenience, and the importance of accuracy. Yes, professional testing comes with a higher price tag, but it also offers assurance of expertise, reliability, and comprehensive analysis. The Professionals follow standardized protocols, ensuring accurate placement of testing devices and thorough interpretation of results. Additionally, professional testers can provide guidance on mitigation measures if elevated radon levels are detected, offering peace of mind to homeowners.

On the other hand, DIY test kits are more budget-friendly and convenient, that allows you to conduct testing at your ease and schedule. However, DIY testing may lack the same level of expertise and reliability as professional testing, potentially leading to inaccuracies in results or misinterpretation.

Ultimately, the choice between professional testing and DIY test kits depends on your preferences and priorities. You might prioritize accuracy and peace of mind, or it could also be the other way round, i.e., cost-effectiveness and convenience over anything.
