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

The Radiacode website has a great isotope spectrum library: https://www.radiacode.com/spectrum-isotopes-library All of the spectrums are from the mobile app for the Radiacode so don't have a massive amount of detail, but there is some great information for each isotope, such as half life, emission lines and a decent description of where they may be detected.

Here are a couple of interesting videos taken inside the damaged Chernobyl reactor 4. The following comment was posted on the first video that lends a little information about who and when the video was recorded. The second video (in Russian) I picked up from the comments of the first as someone was asking what kind of protective clothing did they wear. It's not quite as interesting as the first video, but still interesting nonetheless. Comment from the first video by user J4yChu: I’ve researched, and come up with a few things about the video! The person filming is Alexander Kupny. He was a

On a radmon.org forum thread we sort of got to discussing the thickness of Aluminium for shielding beta but I didn't want to divert that thread too much so started a new thread on this subject here. I had quoted, roughly in all honesty, that 5mm aluminium would do well for beta shielding and was met with this reply by user FSM19: For a beta shield you need 3mm of aluminium, foil isn't thick enough, UK Civil Defence geiger counters and ionisation instruments, such as the Meter Doserate Portable No 1 Trainer, Meter Doserate Portable No 1 and the Meter Survey Radiac No 2 had diecast bodies about

Blackpool UK - 19 July 2017 - Started around 17:00 BST / 16:00 UTC During quite a downpour today, 20mm in one hour. At it's peak was 65mm/h. Background radiation increased by approx 50% / 11CPM over a 2.5hour period. Not much by any means but still an indication there was some radioactive substance in the rain. Please note the Radmon graphs are UTC and the rain graphs are BST (UTC + 1) and so there is an hour difference between them. What caused it? I could be anyone's guess. Radon causing decay products to get caught up in the rain? Radioactive cloud blowing over from somewhere? Radioactive
