After the self-made Geiger Müller counter and the associated experiments, I noticed that there is one or the other radioactive element in our environment.
With the SOEKS 01M Geiger counter, an industrially manufactured device, I have now again “scanned” objects in the area.
Again, I realized that some of the old clocks in my collection are equipped with radium-painted dials. The SOEKS shows here a radiation exposure of about 1.11 microSievert per hour. The environmental load is displayed at approx. 0.14 uSv / h.
But in my mother’s kitchen, I found a beautiful, colorful old vase that displayed about 10uSv / h. (The thing is now in the far corner of the cellar).
It should be uranium paint. (To see orange / red painting in the video below)
