Radonova, the global leader in radon measurement, is taking the next step in its expansion in Canada by establishing a local presence in Mississauga, just outside Toronto. The move strengthens the company’s presence in one of the world’s most developed radon markets and creates better conditions for local logistics, customer service, and future growth.
Across much of the Northern Hemisphere, autumn marks the start of a useful period for measuring radon in homes and workplaces. As buildings are heated and windows tend to stay closed, a long-term measurement can provide a clearer picture of indoor radon levels.
Understanding and measuring radon begins with an understanding of radioactivity. For José Luis Gutiérrez Villanueva, a specialist at Radonova Laboratories, a lifelong interest in the subject has now resulted in the publication of Historia de la Radiactividad (History of Radioactivity), released in spring 2026.
Radonova Laboratories has reached a new milestone. With more than 1,500 SPIRIT radon loggers sold, the achievement represents not only commercial success but also a clear shift in how radon can be measured and monitored in both workplaces and residential environments.
As Radonova celebrates its 40th anniversary this year, it also marks a legacy built upon scientific research, societal needs and technological development. The company’s origins date back to 1986 as a response to the Chernobyl nuclear accident.
It has now been more than 30 years since Radonova first received accreditation for radon measurements. Since October 1995, the company has provided accredited measurements and analyses based on quality assurance, traceability, and independence. Today, Radonova is one of only a few laboratories worldwide that can demonstrate such a long and uninterrupted history of accreditation in this field.
As we move into 2026, the radon issue is entering a new phase. For several years, the primary focus has been on establishing regulations and reference levels, particularly within the EU. Now, however, there are clear signs that more authorities across Europe are beginning to enforce these requirements, especially when it comes to radon measurements in workplaces.
The 2025 Radon Week, held in Warsaw, Poland, from November 3–6, served as a critical platform for advancing radon mitigation and public awareness. The event successfully unified researchers, policymakers, and industry professionals through two main European Radon Association (ERA) cornerstone events: the ERA Workshop and the ROOMS (Radon Outcomes on Mitigation Solutions) conference.
An increasing number of people want to know the true level of radon in their homes or workplaces. But which method provides the most reliable result — short-term or long-term measurement? Radonova explains the differences and why long-term measurement is generally the best choice.
To understand and manage the problem, it is important to know where radon comes from, how it is measured, and what actions can be taken. However, one key message remains: radon is radon. Regardless of its source, the health impact is the same, and the overall exposure over time determines the risk.
Because it can easily seep into indoor environments, radon levels are strongly influenced by how homes and buildings are ventilated. Understanding the link between radon and ventilation is therefore essential to preventing health risks and ensuring safe indoor air quality, whether in private homes, apartment buildings, or workplaces.
As autumn arrives in the Northern Hemisphere, the radon measurement season gets underway. For anyone who wants a reliable annual average of radon levels in their home, apartment building, or workplace, now is the time to start. The colder months, typically between October and April, create the conditions to measure and analyze radon levels over time.
There are certain situations when it’s particularly important to check radon levels. Buying a home, renovating your home, and changing ventilation systems are some examples. Outdated measurements are another. An accredited measurement helps avoid long-term exposure, which increases the risk of lung cancer.
Every summer, millions of holiday homes across Europe open their doors for the season. It’s estimated that there are between 30 and 40 million such properties in use. For many, these homes represent relaxation, nature, and quality of life. But they can also come with hidden health risks, like radon.
When experts and decision-makers from around the world gathered in Quebec City for the 14th annual radon conference hosted by the Canadian Association of Radon Scientists and Technologists (CARST), Radonova Laboratories and radon specialist Vanda Jakabová were there to share new findings on radon mitigation.
Radonova has long been an active contributor to global efforts to spread knowledge about radon and its impact on human health. A recent example is the company’s expert, José-Luis Gutiérrez Villanueva, who will be speaking at a training session in Madrid on April 3. His lecture will focus on radon, its health risks, and the legislation governing the field.
Radonova Laboratories will participate as a gold sponsor at CARST’s annual conference, taking place from April 23–27 in Québec, Canada. CARST (Canadian Association of Radon Scientists and Technologists) is an industry organization with over 300 members, including companies like Radonova.
The European Radiation Dosimetry Group (EURADOS) organizes one of Europe’s most important events in the field of dosimetry and ionizing radiation. This year’s conference will take place in Bucharest, Romania, from February 24 to 27, bringing together leading experts, researchers, and organizations in radiation dosimetry – including Radonova.
Measuring radon regularly is crucial to ensure that radon levels in a home or building remain below recommended reference values. Including radon measurement in regular building maintenance is a rational strategy to prevent problems.
Radon, the invisible and odorless gas naturally found in soil, has garnered increased attention in recent years due to its potentially serious health effects and the need for effective measurement and mitigation solutions. José-Luis Gutiérrez Villanueva, an expert at Radonova Laboratories, identifies three key trends expected to influence the field of radon in 2025.
