In this video we’re going to be looking at a Radiation Survey Meter called a “Meter Survey Radiac No.2”. It was made in England in 1955 by a company called E.K. Cole Ltd. It contains a delicate vacuum tube, and needs special batteries which are no longer in production.
It was listed on eBay as…

Ingenious ideas for the 30V battery, I had no idea how you were going to do that. BTW I would have gone for the same wire 😂
Fascinated by your Wi-Fi connected radiation detector device!! Will look for details 🙂
Isn't the ion chamber comparable to a capacitor in some way? Since condenser microphones compares the capacitance between some terminals
What soldering iron are you using as the beep hears indentical to mine 😛
30v battery 16.99 on Ebay and available Amazon
The movement of the needle when moving the instrument through air is normal if the circuit is not shielded. Static electric fields are everywhere, and an electrometer circuit like this is more than prone to detect them, or to be more detailed, detect their changes if exposed to such a field. I suppose, if you close the casing then these fluctuations are mostly gone.
That's an amazing find and interesting 'restore it' video. I bet your old school science dept. would love seeing that and maybe they've got a small sample for you to test it on 🤔
Old watches with the luminescent white/green are radioactive just slightly, try them. Learnt that in school when I was a pup…
bake the moisture indicator normaly works.
the meters in those are 50ua fsd units fwiw.
birkets of lincoln had these for £5 a pop,unobtainium batterys tho,that insensitive,if it ever read you were already toast!.
It's so interesting watching your videos seeing how you repair everything. From a guy who can't even repair a simple microwave 😅
Once you have the unit properly reassembled, your fingers will have little affect on the meter, although you MIGHT see a tiny bit if you have the beta window open and you put your finger right next to it-this will be caused by static electricity.
Also, I believe that for the beta window to operate properly, you may need to leave the bottom cover off(check the manual though).
A good bit of history and saved and the ending was very good 😂😂👍🏼👍🏼
I would try using a vacuum pump to dry it out. That’s how they do it in refrigeration. I don’t know if they make a chamber that they could hook up to you could put that into. Just a thought!!
You can get a radioacive source from a smoke detector
You could weight desicant before and after dry
Brilliant vid! Love to see that old tech. It really was built to last.
Great stream, loved the ending, thanks Mick 😁
You can often get rounded out socket screws removed by tapping a torx bit into it.
Get your self an old ionizing smoke detector and use the Americium 241 source from it to test your unit
after a close look that's no Colin Furze's bunker, tunnel or garage, the curve of the tunnels and the placement of the steel beams is not the same, but i am really curious to know ho has this bunker
🤣🤣🤣🤣🤣😂😂😂😂😂😂😂😂😂😂😂😂👍👍👍👍
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
I wonder if these valve devices continued to be used into the mid eighties because transistors can be damaged by the electromagnetic pulse produced by atomic weapons but valves are unaffected? Or maybe the kit just worked, the quality of the piece is amazing.

Humidity Indicator Paper (Cobalt chloride free) ia available from Johnson Papers. The old pink stuff you have there is harmful hence the cobalt free version. I really enjoyed your video. thank you.
What about using an ionisation smoke detector to test it, would that be enough to trigger it? Plus easy to get hold of them.
Nice Vid, the Silica beads can be dried out we used to have cabinets of the stuff when I was at the REME in the 70's.
Looks like this detects beta / gamma radiation and not alpha emission. An explanation might have helped. Also mention secondary emission from aluminium shielding around high energy beta emitters. The public is mostly protected by regulation but this is no place for play by the uninformed !
That ending was so good!
Fascinating. This farming malarky really is dangerous.
Wow well presented Mick, lovely unit and still working what a bonus, really enjoyed it, I used to work for Graseby Dynamics Limited (Watford) they were the company that supplied personal and vehicle ‘Agent Detectors’ for the MOD, Army etc, we would get the used units strip them down and empty them out, they are then washed for 3 days and then dried for 5 days ( something like that ), then refilled with charcoal granules and sealed. We weren’t allowed to use deodorants or aftershaves, also we had to wash our hand before entering the department otherwise an alarm will sound, it was great I still have the small clock I received from them 😊
Didn't know Colin was a mate, Mr furze for the win
Very nicely done and thought out! Cheers
