Radioactive fog. Over 10x on motorcycle leathers. June 30th 2013
Firstly apologies for shaky and short video. My memory card was almost full so only had a few mins on a low resolution setting.
Location: South Devon, England
Weather: Foggy
Ten min timed count: 316.2cpm
(34cpm is my normal background)
Time: around 05.29hrs GMT
Date: 30th June 2013
Altitude 92meters (my home)
Geiger counter: Inspector EXP+
Info:
I left a friends house about 04:10hrs in Torquay (my home town) to travel back home (the slightly longer way for safety as the shorter way was more foggy as there were many higher elevations points so the fog would have been even thicker but it was still bad.
Anyway I got home and the first thing I did whilst still in all my leathers etc was take a 1 square meter swipe off my car as there was a lot of moisture on the car, maybe it had rained or it was morning dew etc. This sample only measured max 80cpm (peak, no timed count), so I binned that swipe and thought why not check my motor bike books and was amazed to see a few hundred cpm (counts per min).
Anyway I must have got exposed to the radiation in the fog somewhere between Torquay and 6-8 miles from home. Riding in thick morning fog on a motor bike in low light is not the most pleasant of an experience as the fine water vapour just sticks to the visor so visibility is very poor.
My leathers etc were practically dry except for my visor and a damp area on toes of boots and my left index finger of my leather gloves as I was using this to wipe/clear my visor but the finger on the gloves were only damp. I decided to do a timed count of this part of my glove. I would add that although dry other areas of my leathers like forearms, shoulders etc were also pushing over 300cpm
I shot the video above several minuets before I started a ten min timed count of my left index finger of my left motorcycle glove but some 30mins had elapsed since I had got home but also a further 10mins had passed I would say as I wasn't ridding in any fog for the last 10min or so of my journey so approximately 40mins had passed since I last was exposed to the fog and started the test. Therefore talking into account the half life one could make a rough calculation and say that at its peak ie when I was in the fog the actually CPM could easily have been much higher as the half life was 52.6min and 40min or so had passed since I started the test so I perhaps easily 500cpm as a rough estimate.
The results of the ten min timed count came in at 316.2cpm.
I conducted a follow up study to find the half life.
The half life was 52.6min which I confirmed through two half life steps.
52.6min happens to be the half life of Iodine-134 (I-134)
Iodine-134 is a beta emitter so I checked to see what type of decay was being emitted from my contaminated leathers mainly my glove.
I did this by blocking any possible alpha radiation by placing a sheet of paper between the glove and the GM tube to see if the radiation being measured would drop, I also re did this test with a thick piece of card instead of paper, there was no difference therefore this showed that this was a beta and/or potentially a gamma emitter. I then placed a 2-3 millimetres of aluminium between the glove and the GM tube and the levels dropped completely off. So this was proof that it was 100% a beta emitter. And the fact that I-134 is a beta emitter and it's half life match what I observed well......hummmm!
Time:
05:29hr.................316.2cpm
52.6min later..........150cpm
52.5min later...........73.5cpm
Accuracy of Inspector EXP ±10% - 15%
The low level wind data I saw didn't give me any indication where this came from but the jet stream, and more importantly the slow moving air mass of the jet stream was over my location.
If indeed this was I-134 where did it come from. This I am certain was not any radon or radon progeny as the half life proved this. That bit was for the trolls lol
Be safe people!
