A while ago I broke my favourite mug. After a long and difficult search I found a new mug. A mug with the periodic table of elements entry for uranium on it. It also glows in the dark. Gav from the hacker space has a Geiger counter so I took the opportunity to measure the radioactivity of my mug. Luckily it’s not radioactive at all. Only 0.106μSv/h (micro Sieverts per hour).
