Radon Maps Do Not Show Radon Levels in a Specific Building

By | Radon Education | No Comments

‘Radon maps’ is a term that frequently crops up when talking about the risk of radon. A radon map provides a general picture of the areas where there is a risk of high radon levels. These maps are available at both national and regional levels. However, the problem with a radon map is the false sense of security it can give regarding a specific building.

Despite this, Radonova is seeing a growing number of cases where private individuals and workplaces are using radon maps to try to determine the radon level in their specific indoor environment.

“Radon maps are designed to be used when you want a more general geographic breakdown of low-risk and high-risk zones. It is, however, very difficult to draw any reliable conclusions from these about radon levels inside a particular building,” comments Bill Rounds, President at Radonova.

“The relevant authorities and experts often have good knowledge of the applications for which radon maps can be used. Problems tend to arise when the general public draw conclusions from the maps about radon levels in their own home.”

This is why radon maps do not show radon levels in a specific building.

Below are some of the reasons why radon maps are not a reliable tool for determining radon levels in a specific building.

Radon maps do not show local variations

When producing a radon map, very few measurements are performed in a specific area. Radon levels can vary significantly in such a large area and even between buildings on the same street. Indoor radon levels largely depend on the building’s construction and the air permeability of the soil, which can vary locally.

There is no standard for the production of radon maps

To produce a radon map, measurement data is either obtained by measuring ground radon levels or using data from indoor measurements in the area. With ground radon measurements, there are no clear links between the level of radon in the ground and indoor radon levels. There is certainly an increased risk with high ground radon levels, but other factors, such as construction technology, can have a greater impact.

However, if the radon map is based on indoor measurements, then the results are heavily dependent on the type of building structure where the measurement was recorded. This in turn need not be relevant in any way for another building close by.

Radon can be emitted by building materials

Radon maps use an accumulative average to represent an area’s general risk and cannot account for individual factors.  For example, building materials like blue lightweight concrete used in foundations and aesthetic upgrades that incorporate natural stone emit radon and has the potential to impact results.  Because this can cause outliers in “low” radon areas, it’s important to measure each building regardless of its location on a radon map.

The maps can be generated from old data

Measured radon levels are to some extent ‘perishable’. A measurement taken from a few years ago, for example, is no longer reliable. A lot may have happened over the years in and around the building in question to change radon levels. Modernizations, changes to ventilation, and groundwork are just a few examples of factors that can have a major impact on indoor radon levels.

“With this in mind, you shouldn’t rely on radon maps if you want to know what the radon levels are in a specific building. Even if you live in an area that is defined on the radon map as a low-risk zone, there may still be very high radon levels indoors. Given that radon, after smoking, is the most common cause of lung cancer, there is every reason not to rely on this type of map when trying to determine radon levels in the home and at workplaces,” concludes Bill Rounds.

Measure in the building

The only way to get a reliable picture of radon levels in indoor air is to measure them. This can be done in an affordable manner using radon detectors. Radon maps still have a role to play, however, as they can provide the authorities with an overview that makes it easier to prioritize inspection efforts.

Radon as a Health Risk – WHO report

By | Radon News | No Comments

The WHO’s latest report ‘Guidelines on Housing and Health’ describes how people’s housing and health are affected by a variety of factors. The report describes radon, among other factors, as a health risk. The report draws attention to the fact that radon should be regarded as a carcinogen on a par with tobacco smoke.

The harmful effects of radon are emphasised by, among other things, the WHO wanting to reduce the reference level for radon in home environments to 100 Bq/m³. That is one-third of the reference level established in Directive 2013/59/EURATOM, which is 300 Bq/m³.

 Radon Causes Lung Cancer

Radon as a health risk is a global problem that each year is estimated to cause around 230,000 cases of lung cancer, which has a high mortality rate. Radonova’s measurement expert José-Luis Gutiérrez Villanueva comments on the latest WHO report:

“It is important that radon is not singled out but regarded as one pollutant among many. In this respect, the WHO’s report is clear and important. The report describes the harmful effects of radon, as well as how preventive measures can be used to reduce harmful radon levels. Bearing in mind the fact that radon causes a very high number of lung cancer cases, it is vital to speak plainly about this issue.

“While radon is a global problem, the WHO’s report makes it clear that radon needs to be tackled at national level. In order to be effective, each country needs a well-developed programme that can be adapted to the circumstances in each case.”

José-Luis Gutiérrez Villanueva has worked on radon issues for the last 15 years. He wrote his PhD on ‘Radon concentrations in soil, air and water in a granitic area: instrumental development and measurements’ (University of Valladolid, 2008), and is an expert in areas including data analysis and different ways of measuring radon. As secretary of the European Radon Association, José-Luis also has extensive experience of international work with radon.

The Lung Association – Ontario to Provide Radonova’s Rapidos and Radtrak2 for Home, Workplace and School Radon Testing

By | Radonova News | No Comments

Through its partnership with Radon Environmental The Lung Association – Ontario is providing Radonova’s radon detectors to consumers to offer a fast, efficient, and accurate way to find out if your home, school or workplace has potentially hazardous indoor radon levels. The detectors supplied by The Lung Association – Ontario gives the public the option of choosing either a short or long-term test kit. All test kits provided are recognized by Health Canada and C-NRPP certified.

“The air you breathe, regardless of where you live, work, or socialize, is important to your health. The Lung Association is committed to protecting your breathing and that’s why we’re excited about this new partnership and being able to offer a variety of radon test kits for the public. Testing for radon is simple, convenient and inexpensive. With these do-it-yourself kits, it’s easy to follow the instructions included and test your home,” says George Habib, CEO of The Lung Association – Ontario.

Rapidos is a short-term radon measurement test kit that captures a measurement of radon levels over a period of 10 days. Online analysis and measurement reports are available from Radonova’s laboratory within 1-2 weeks after the laboratory has received the detectors. Both accurate and flexible, Rapidos is one of the most effective ways to measure radon in residential buildings, workplaces and schools.

Radtrak2 is Radonova’s flagship long-term Radon test kit and tests home’s and office’s for radon over a sustained period. With ultra-high accuracy over a prolonged period of time, it provides a full and clear perspective on the risk of radon exposure in the tested location.

Radon is an invisible, odourless and tasteless gas that can accumulate to unnaturally high and dangerous levels in homes and workplaces. Radon is the second most frequent cause of lung cancer, after cigarette smoking and the leading cause in non-smokers. Young people and children are more vulnerable to radiation as they have higher respiratory rates than adults. However, consumer knowledge on how to detect Radon and meaningfully reduce exposure is low.

Bill Rounds, President at Radonova, said: “We work with strategic partners, like Radon Environmental, to enable our products to be accessed by a wide variety of organizations. Remember, radon gas cannot be detected without the proper equipment. This means, while it is easily remedied when detected, cases of non-detection pose a great risk to humans in an unmonitored house, building or school. We offer state-of-the-art technology which mitigates this risk.”

Radon Environmental President & CEO, Alan Whitehead commented: “We are delighted to have teamed up with the Ontario Lung Association to provide Radonova’s short and long-term alpha track radon detection devices. We supply many local health authorities and public testing initiatives across Canada with these devices and our partnership with the OLA will lead to increased public awareness and radon testing in Ontario.

By | Radonova News | No Comments

Radonova kicked off a very busy upcoming radon conference season with back to back shows at the Las Vegas International Builders Show, the EPA Region 7 Stakeholders meeting in St. Joseph. MO, and rounding out the week with a ‘home-court’ event at the Midwest AARST Stakeholders Meeting in Oakbrook, IL.

2019 International Builders Show – Las Vegas, NV

At the IBS event, we joined one of our biggest partners, Radon Environmental Management Corp, at their booth. With the event focused on builders and new construction, radon testing and radon resistant new construction were a primary focus. REMC’s mitigation products, the Airwell and Radon Guard were on display alongside all of Radonova’s testing devices. A spot near the booth was in demand when Mike Holmes and Mike Holmes, Jr. stopped by for a Facebook live event promoting their ‘Make It Right’ mission and in support of REMC and Radonova’s Homles Approved products.

2019 EPA Region 7 Meeting – St. Joseph, MO

EPA Region 7 had a positive showing this year, hosted in Missouri and consisting of measurement specialists, mitigation contractors, and state officials from the entire region. Consisting of Missouri, Nebraska, Iowa, and Kansas, this region is extremely hands on due to the higher radon concentrations typically seen in homes in the midwest. Kansas State University assisted with the production and both days were filled with engaging speakers and radon plans at the state levels to get all residents testing for radon. We had the privilege of having our own booth at this event and were happy to be partnered near Alpha Energy Laboratories, David Smith Radon Supply, and the NRSB certification board. For a quick trip, it was great to see a lot of our industry partners and supporters.

2019 – Midwest AARST Annual Stakeholders Meeting – Oakbrook, IL

MWAARST rolled into Oakbrook again March 7th and 8th. Being one of the largest and most attended AARST chapter events, talks and participants needed to be split into 2 days with record attendance being capped and closed BOTH days! Being right in Radonova’s backyard we definitely wanted to help out this year. In addition to being a gold sponsor in attendance with our own booth, between the two days we were able to have every Radonova employee in attendance. Thursday night, during the Radon Mingle, Radonova upped the ante and brought of some of the most delicious appetizer offerings Pinstripes had to offer. The evening capped off by dinner with a handful of industry partners, including some of our friends at Spruce and Eric Lewandowski from Professional Radon Systems and the AARST Board of directors. Not to mention, even the days speaker and passionate radon induced lung cancer survivor and advocate, Rachel Malmberg joined us! MWAARST has a lot of irons in the fire and Radonova cannot wait to get more involved and see the next chapter unfold under new president Dan Potter!

With no intention on slowing down, be sure to follow us on social media and be sure to catch up with us at a handful of events all throughout March and April.

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.

Radonova Launches a New Product for Safe Radon Monitoring in Soil

By | Radonova News | No Comments

Radonova Laboratories is launching a new detector that makes it safer and easier to monitor radon in soil. The new Ecotrak® detector can be used ahead of new builds and property modernisations and provides quick, reliable information on the amount of radon in the soil being tested.

Unlike other commonly used soil detectors, Ecotrak® is covered by international comparative tests. The detector is supplied in a Tyvek bag, which protects against moisture, dirt and other factors that could affect the result.

Ecotrak® does not have to be returned for immediate analysis, rather it can be collected and stored at stockists for a short period. This enables more streamlined handling and means that detectors from several different monitoring periods can be sent for analysis at the same time.

“Monitoring radon in soil is relatively simple. The challenge is to monitor it in such a way as to provide a reliable result. In part, this means that the product itself has to be high quality and able to withstand the stresses that are part and parcel of monitoring in soil. However, it also means using an accredited laboratory that takes part in international tests. This enables us to carry out fact-based comparisons with large amounts of reference data,” says Karl Nilsson, CEO of Radonova Laboratories.

“With the new Ecotrak offering we are  making it simpler and safer than ever to monitor radon in soil. No matter what type of construction is involved, there’s value in understanding the radiation source in the ground, and propensity for elevated radon emanations. What’s more, in some cases the local building committee requires a study into radon levels before granting building permits. Should monitoring show that the site is what’s termed ‘high risk’, construction methods can be modified, including radon barriers and other preventative methods,” says Bill Rounds, President at Radonova.

Ground radon in brief

Uranium and radium are the two elements that contribute to the levels of radon gas found in soil. Levels of radon gas can vary widely depending on the type of soil. As a general rule, the airier the soil composition, the higher the level of radon. Conversely, a more compact composition makes it more difficult for the radon to circulate in the soil.

Ecotrak® in brief

  • Covered by stringent international comparative studies
  • Not sensitive to moisture (large amounts of water do, however, affect the results)
  • Supplied in a protective Tyvek bag
  • Can be collected and stored for a short period (for efficient handling of multiple measurements)
  • Monitoring usually takes place over one to seven days
  • Can be used all year round (provided the soil is free of frost)
  • The recommendation is to use at least three detectors for the first 100 m² of the site where the property or construction will stand, and then it’s a good idea to have at least one extra detector per extra 50 m².

Radonova Selected as the Testing Laboratory Supporting the Evict Radon Campaign in Alberta, Canada

By | Radonova News | No Comments

Westmont, IL, United States, January 29, 2019Radonova, the global leader in Radon measurement, today announced that it has been selected as the testing laboratory for the Evict Radon province-wide campaign in Alberta, Canada. To date, over 15,000 Alberta homes have been tested. Evict Radon is designed to increase awareness about radon-induced lung cancer and encourage Western Canadians to have their homes tested. Processed in Radonova’s laboratory, the results from a 90+ day test are then taken forward by researchers to understand how our environment influences our radon exposure and health.

Radon is the second most frequent cause of lung cancer, after cigarette smoking and the leading cause in non-smokers. Young people and children are more vulnerable to radiation as they have higher respiratory rates than adults. However, consumer knowledge on how to detect Radon and meaningfully reduce exposure is low.

Evict Radon is a confederation of Canadian cancer researchers and scholars founded to understand Canada’s radon problem through science and eradicate radon exposure in homes to prevent future cases of radon-induced lung cancer. This confederation encompasses Canadian medical doctors, biologists, geologists, physicists, architects, clinical psychologists, communications professionals, and population health experts with a strong track record of innovation, public outreach, and cancer prevention research.

The team innovatively combines grassroots science engagement and citizen science-based research to prevent cancers. Evict Radon is led by Dr. Aaron Goodarzi, an Assistant Professor at the University of Calgary, who is the federally-appointed Canada Research Chair for Radiation Exposure Disease.

Dr. Aaron Goodarzi said: “It is very straightforward to test for radon. A radon test device is smaller than a hockey puck and requires no electricity. You simply place it in the lowest level of the home where someone spends more than four hours a day. Early findings from our study indicate that in rural Alberta, one in six homes are impacted. Right now, we have one Albertan a day diagnosed with radon-induced lung cancer. If Alberta were a country, it would be among the top five on Earth, in terms of radon-exposed populations.”

High River Mayor Craig Snodgrass said: “I’d heard people talking about radon gas in Alberta, but I really didn’t give it a lot of thought until my wife wanted us to test for it. Now, we’ve become advocates of testing, and I’d like to see other mayors in our province encourage their citizens to test for the gas.”

Bill Rounds, President of Radonova, said: “Radon is an invisible, odourless and tasteless gas that can accumulate to unnaturally high and dangerous levels in our homes. Evict Radon is a ground-breaking campaign, which can be used as a template to identify other regions where Radon exposure is high. This will consequently help prevent unnecessary cases of radon-induced lung cancer. As the only global ISO accredited radon measurement provider, we’re fully committed to working with Dr Goodarzi’s team to ensure the project gets accurate results in a timely and professional manner to ensure the concept can be confidently rolled out to other regions.”

The radon kits used in the study costs $60 and are available here. Devices must be purchased by the end of January for the testing to be completed during the winter. Evict Radon re-opens every fall for radon testing.
