Radonova presented research on radon retesting and exchanged experiences on expanding home testing at the 40th annual Indoor Environments Radon and Vapor Intrusion Symposium in Norfolk, Virginia, October 4–7. Formerly the AARST International Radon and Vapor Intrusion Symposium, the event brought together researchers, industry professionals, public health advocates, and government representatives.
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.
