Experiment - Capturing Radon progeny from Uraninite (Uranium ore) This should be quite interesting to anyone that owns or is thinking of owning Uraninite (Uranium ore) sources, and anyone with a keen interest in Radon. TL;DR - Skip to the last part for safety concerns with U-238 sources and also Thorium gas mantles, Thorium dioxide. This was a fairly well controlled experiment that was carried out at home, and using ChatGPT as my lab sidekick. The idea was to capture Radon progeny from 4.46g of Uraninite (Uranium ore) and prove the decay products. Uraninite emits Radon gas and this decays

This time I get out my I Never Won A Blue Peter Badge badge, a stack of foam board, some sticky tape, more sticky tape, some hot glue, some recycled fabric insulation stuff from a dishwasher and knocked together a box for insulating the heat absorbing temp sensor. Not much really to say about the construction. I think the pictures say it all. This is the end product and really does appear to work well. It managed to record a temperature of just above 70°C a few days ago. 😯 That's about 20°C more than before it was in the insulated box. It still needs some small tweaking as when I open my

I have been meaning to write an update as I have added a couple of new sensors. One of which is my very own invention - straight from the old grey matter. I have also made some improvements and things seem pretty stable. I have improved the web pages for displaying the data and is now easy to go back and forwards day by day to view the data. For some reason the ESP32 started counting something like 10x the actual counts from the counter. I think this happened after I added an AS7341 sensor, or something. I have had other issues with the ESP32 slowing to a crawl. I guess this is what happens

Solar Monitor 5 Million I have been meaning to write this up for a couple of weeks now, and I finally do it. This is an experiment I am conducting (very loosely at present) that came about from leaving my CAJOE RadiationD-v1.1 with J305by on my window sill for a week and noticed a strange pattern with the 'excess' counts. They were stronger in the morning than in the afternoon, even to the point they were stronger than in direct sunlight. I mentioned this to a couple of members here and we all agree that it is strange, and that we all expected there to be more counts in direct sunlight than
