Vintage Illuminated Watches, Clocks and Dials Emitting Radon

By | Blogs | No Comments

In the beginning of the 20th century, scientists developed a way to mix “radium 226” with paint. This created ‘radioluminescent paint’. This breakthrough led to the new product being applied to clocks and telephones. Even airplane instrumentation panels (all now considered to be vintage), enabling the devices to glow in the dark.

However the new approach led to unforeseen circumstances. By 1925 a group of radium painters, later referred to as the Radium Girls, sued their employer over health issues. This was believed to be stemming from the ingestion of radium through a practice called ‘pointing’ their brushes. They would lick the ends of the brushes to refine the bristles into a point. Subsequently ingesting radium remnants from the brush. As a result, by 1930 ‘pointing’ brushes was no longer done by mouth and there were no more incidences of malignancy due to radium. This led most people to believe that radium was not a health risk provided you did not consume it.

Sixty years later researchers from the University of Northampton wondered whether since radium decays into radon gas, “vintage” clocks, watches, phones and such items, previously coated in radium paint could influence radon gas levels as the radium naturally decays.

The study was performed in a small bedroom and consisted of measuring the radon gas level for a baseline. Then adding 30 radium dial watches to the room to see how much the radon level would change, if at all. Upon retesting it was discovered that the room’s radon level rose to 134 times the level at which the EPA (United States Environmental Protection Agency) recommends action.

The data from this first study of its kind indicates a previously unconsidered risk. This was from owning, collecting, and storing radium dial watches or other items coated in radium-infused paint.

So keep calm, and think before you go vintage.

Acquisition of Gammadata provides Radonova with a Complete Program for Radon Measurement

By | Blogs | No Comments

By acquiring the radon measurement instrument division of Gammadata Instruments, Radonova Laboratories has further strengthened its position as a world leader in home and workplace radon measurement. Through the acquisition, Radonova has added several advanced instruments and products to its portfolio. Broadening its range of radon measurement technologies.

By offering a comprehensive program for radon measurement, Radonova is responding to the global demand for safe and efficient radon measurements in homes and workplaces.

“With this acquisition, we get access to leading edge products which are at the absolute forefront of research and development. For example, ATMOS, the world’s most sensitive radon sniffer. We now have an expanded portfolio of instruments and products. We are in a position where we can offer new and existing customers an optimal radon measurement program. Particularly in the rapidly growing European market of workplace radon measurement,” says Radonova Laboratories CEO Karl Nilsson. One of Gammadata’s founders, Dag Sedin, has 30 years of experience in instrument development for radiation measurement. He will take on the role of consultant at Radonova Laboratories. Dag comments on the acquisition:

“As we are now part of Radonova Laboratories, there is enormous potential for intensifying our research to ensure that we continue to deliver the most innovative radon instruments and sensors available on the market. Radonova provides us with a great platform to further develop the new product lines we have in the pipeline. The first of these will be an update to the ATMOS radon sniffer. In addition, Radonova has an established export network that will provide numerous new opportunities for growth when new products are released.”
