May 3, 2024 | #589 Measure Gamma Rays with a Photodiode: Radiation Detector Using a BPW34 The first device that springs to mind when thinking about measuring radioactivity is the Geiger-Müller tube. However, these counter tubes can be difficult to find and expensive; and, even if you do manage to get hold of one, you will still need to find a way to generate its operating voltage of several hundred volts. It is less well known that even a humble photodiode such as the BPW34 can be used to detect X-rays and gamma radiation. more...

So naturally, I don't get the benefit of it. I recently asked my former meditation teacher for advice. He asked me back: "What's holding you back?" "I don't have enough time," I started typing (this was on Facebook Messenger). Then I deleted it because I realized that I could do it in as little as 5 minutes per day.
