On 1 October the radon measurement season got under way in Sweden. You can actually measure radon all year round, but if you want an annual average for radon levels in your home or workplace, you have to measure them over the course of at least two months during the winter when heating systems are on. In Sweden this is between 1 October and 30 April. In practice, this means you have to start measuring radon levels by the end of February.
We met up with Oscar Wännerud, who is in charge of the world’s leading radon laboratory. Here Oscar describes the measuring and analysis work carried out during peak season, and talks about how Radonova handles tens of thousands of detectors a month.
In brief, how would you describe your daily work in the lab during peak season?
We are now at the start of the season, so we are working on large volumes of deliveries.
Our automated production of radon detectors has been ramped up, running at top speed, from six in the morning until midnight. This is needed so that over the autumn we can supply 80,000 detectors a month.
In December, the detectors start to come back in, as at that point many customers will have been able to measure over two months. At that time we are still sending out large volumes of detectors. In the spring there are fewer deliveries to be made, as the measurement season is drawing to a close. At that stage the work switches to processing and analysing large volumes of radon measurements. International customers often measure all year round, resulting in a more even flow for these customers. This also means that we run all processes all year round but with varying volumes.
Are all analyses conducted at Radonova’s laboratory in Uppsala?
All radon detectors are manufactured in Uppsala and then distributed across the world. The same applies when customers have completed their measurements. The detectors are sent back to the lab in Uppsala for etching, reading and analysis. This requires reliable, effective and well-functioning procedures and processes for both outgoing deliveries and incoming deliveries of exposed detectors. We need a rational and tightly controlled approach to be able to handle the large volumes we deal with.
Have any new issues or challenges arisen this season?
The work has so far been characterised by increased volumes and rapid delivery times. We are selling more measurement services than ever, yet we have still managed to further reduce delivery times. All so we can give our customers the best possible service.
What do you feel is the recipe for success when it comes to reliability and assurance?
Accreditation is an important base for a monitoring laboratory. We really benefit from being audited by external bodies. Well-established procedures in combination with ongoing improvement work are required for us to be able to remain at the forefront within radon measurement. We are also involved in various international comparative tests in order to ensure that our processes maintain a very high level.
Have you got any general tips for companies or private individuals who are intending to measure radon?
It is simple to measure radon using Radonova’s services. Via “My Pages” you get full control of your data and can easily export it when needed to either PDF reports or Excel files for further processing/statistical purposes. When our customers use My Pages to record data, we get immediate access to the measurement data. This in turn produces quicker analytical results. Another upside to using My Pages is that it minimises the sources of errors, which can easily arise when work is performed on paper and is characterised by multiple manual steps. Via My Pages customers can easily supplement data and get rapid responses.
How do you think things are going to develop in radon measurement?
Automation and digitalisation are the two biggest future trends. The combination of automated processes and customers having increased access through digitalisation will be a crucial success factor. We expect to minimise lead times for outward delivery, but above all we will be reducing the time it takes to perform analyses. I am also convinced that Radonova is ideally positioned to continue as a global leader in the measurement and analysis of radon samples.
