Short-term measurement of radon: the right choice when selling a house

By | Home | No Comments

Radon is an issue that frequently crops up in connection with the sale of a house. When time pressures are a factor and quick decisions are needed, up-to-date and reliable measurement of radon levels in the home is often overlooked. One solution in these cases may be short-term measurement. Correctly performed short-term measurement provides both buyer and seller with an indication of the radon level and data that can simplify the process going forward.

The world’s most accurate short-term measurement

In order to meet demand for reliable measurements, Radonova has developed the world’s most accurate radon detector for short-term measurement – Rapidos. Rapidos is currently used the world over and often in connection with the sale of houses. So what makes Rapidos better than other radon detectors?

The most important features that distinguish Rapidos from other detectors are:

  • Option to measure radon levels as low as 50 Bq/m³
  • Extremely reliable result compared with other solutions for short-term measurement
  • Safe, date-marked vacuum packs for delivery of the radon detectors
  • The market’s fastest analysis and response times

Rapidos can measure radon with a relatively high degree of reliability, as the detector’s measurement volume is two to three times greater than that of other brands. The measurement volume is the amount of air contained in the detector’s chamber (where the actual measurement process takes place). A larger volume enables you to measure more alpha particles, which form when radon decays. This in turn provides broader and better data for the actual analysis.

High quality across the board

The ability to perform very precise short-term measurement is also down to the uniquely clean film element that is used during manufacture of the radon detectors. In order to achieve an accurate analysis, it is important that as few tracks as possible are made during the manufacturing and packaging process (i.e. before measurement begins). These tracks are called background tracks. Radonova’s closely monitored manufacturing process is performed in a clean environment with full traceability to keep the number of background tracks to a minimum. In order to avoid exposing the radon detectors to radon during transport, all detectors are also packaged in a vacuum. This makes it easy to see whether a pack is leaking.

Radonova regularly participates in various external comparative tests to guarantee consistently high product quality. Radonova’s radon measurements are also audited annually by a third-party auditor that issues certification in accordance with ISO 17025, ISO 9001 and ISO 14001.
Radonova’s short-term measurements also surpass other solutions by offering the market’s shortest delivery and analysis times. This is particularly important when selling a house, which often involves time pressure.

Radon in brief

Radon is an invisible gas that comes from the ground and is present in the air we breathe. Radon decays into radon progeny, which are radioactive metal atoms. These get trapped in our airways and emit radiation. In this way, high levels of radon can cause lung cancer.

Elevated radon levels are the biggest carcinogenic health risk you can be exposed to as far as indoor air is concerned. Globally around 230,000 people develop lung cancer every year because of elevated radon levels.

Canadian radon project chooses Radonova for analysis of radon samples

By | Measurement, News | No Comments

Swedish Radonova Laboratories has been commissioned to analyse radon samples in the major Canadian campaign “Evict Radon”. This campaign aims to reduce the incidence of radon in Canadian homes and lung cancer as a consequence of long-term exposure to radon gas. This campaign being conducted in the province of Alberta is headed by Dr Aaron Goodarzi at the University of Calgary.

Radon is measured for at least 90 days and analysed at Radonova’s laboratory. The results will form the basis for continued studies on how radon exposure affects the environment and the health of residents. The project involves doctors, biologists, geologists, architects and experts from a number of other fields. It is estimated that in parts of the province of Alberta, one in six homes is affected by radon. And every day one resident is diagnosed with lung cancer caused by radon.

May become a template for similar projects

“We are naturally proud that such a large and important project has chosen Radonova as its partner for analysis of its radon measurements. At the same time, we know that Radonova is the only operator with global ISO certification. We currently occupy a very prominent position when it comes to radon measurement and analysis. In this role we always want to play an active part in the work of reducing unhealthy exposure to radon. The Evict Radon campaign seems particularly important, as it is comprehensive and well planned. This means in turn that after the campaign has ended it can act as a template for similar projects,” says Karl Nilsson, CEO of Radonova Laboratories.

After smoking, radon is the most common cause of lung cancer. This makes radon a serious global health problem that every year leads to around 230,000 cases of lung cancer.

Radonova joins metroRADON

Radonova becomes part of Europe’s largest radon project

Radonova Laboratories has joined metroRADON, Europe’s largest project studying radon issues and measuring equipment.

The members of metroRADON are the foremost national operators in Europe and include both companies and various universities and research institutions.

As part of the interest group, Radonova will contribute its long experience of radon measurement with passive devices, i.e. various kinds of sensors and radon detectors.

metroRADON

The interest group and project metroRADON stand for ‘Metrology for radon monitoring’. This radon project is funded by EMPIR (the European Metrology Programme for Innovation and Research).

“It is natural for Radonova to play an active part in this interest group. The issue of radon is largely addressed from a global perspective. The exchange of experience and research has a major bearing on each country’s ability to reduce the harmful effects of radon on health,” says Radonova Laboratories’ CEO Karl Nilsson.

“Radonova has been to several meetings of metroRADON during the year and now becomes an active and effective member of the consortium. We intend to contribute valuable knowledge in the field of radon monitoring while taking a closer look at the research and experience from other countries,” says Radonova Laboratories’ radon specialist José-Luis Gutiérrez Villanueva.
