Radonova Introduces Individual Date-Marking for Detectors Used in Radon Monitoring

By | Radonova News, Uncategorized | No Comments

Together with the recently launched vacuum packaging, the unique date-mark ensures that the monitoring and analysis work can be carried out with the utmost reliability.

Tryggve Rönnqvist, technical manager at Radonova Laboratories, describes the benefits of date-marking the detectors:

“By date-marking each individual pack, we further increase the measurement certainty of short-term monitoring. If radon monitoring is carried out over seven to ten days after the detector has been stored for a year, this could have some effect on the result. Quite simply, it’s more difficult to measure lower concentrations reliably if the monitoring period is short and the storage time is long. Even though we’re talking about small deviations, we always strive to give our customers the most accurate monitoring results possible which is why we have updated the way we manage our inventory stock.”

Easier for stockists and customers with their own stock of detectors

“Above all, per device date-marking makes life easier for international stockists and customers who previously ordered date-marked boxes of radon detectors. Now they can quickly see how old each detector is and optimise their warehouse logistics accordingly. Real estate agents are another good example of businesses that benefit from clear date-marking. Monitoring is often fast and frequent in this segment and many agents, therefore, often have their own supply of detectors. By date-marking each device, we’ve made it easier to use the detectors in the right order.”

“Although our monitoring is already at the very forefront of reliability, clear date-marking of each detector and the newly introduced vacuum packaging helps us to offer even simpler, more reliable radon monitoring.”

The newly launched vacuum packaging provides a maximum storage time of eight months for short-term monitoring and three years for long-term monitoring.

Radonova also recommends beginning long-term monitoring within 18 months because the measurement uncertainty decreases the sooner monitoring begins. For further information about radon and radon monitoring, contact us here.

LANDAUER RADON is now Radonova

New name, exciting new developments, same commitment to radon science,

product innovation and customer service.

WESTMONT, Illinois (May 15, 2017) —Effective Monday, Landauer Radon will officially begin operations as Radonova. The planned transition commenced with a name change from Landauer to Landauer Radon when the business first separated from Landauer, Inc. with the financial backing of Lagercrantz.  Now, after thoughtful deliberation, the company has unveiled its permanent new identity.

Aside from a new name, it will be business as usual.  Radonova will continue to offer its high-quality radon measurement products, manufacturing, analysis and protection plans.

This move has been extremely positive for Radonova customers. With the strong financial backing of its parent company, Radonova has been able to devote more resources to quality and R&D than ever before.  Radonova has spent the transitional months not only formulating its new identity, but enhancing its service model, implementing tighter quality controls, perfecting a global, integrated analysis solution and preparing for the launch of game-changing radon detection technology.

“Because we are now a part of the Lagercrantz Group AB, it was the logical choice to rename the company,” says Karl Nilsson, Radonova CEO. With our proprietary Radtrak2® and Rapidos® radon detectors, and our state-of-the-art laboratory, we will continue as the world leaders in qualitative radon measurement, with a heavy focus on exceeding customer expectations regarding quality, service and handling.”

Although the company’s identity has changed, its long-standing reputation has not. Built on the backbone of Landauer, Inc. (NYSE: LDR), an industry leader in radiation dosimetry, Radonova will carry that leadership legacy forward in the radon industry.

There are exciting developments on the horizon. Over the coming months, Radonova will continue to enhance RadOnline, a private back-office system that allows customers 24/7 access to every piece of data collected across every radon measurement project. The company is also positioned to launch a new detector.

“We couldn’t be more excited that our transition is complete,” adds Bill Rounds, Radonova Vice President. “With formalities out of the way, we can turn 100% of our focus back to core business and innovation, including the upcoming launch of our newest detector, Duotrak®, which measures radon in two positions and affords users ultimate control of the active measurement time.”
