Just as a point of interest, I used to work at a USDOE national lab. We were still using quartz fiber dosimeters as recently as the early 2000's. For all I know, they may still be using them, although the last time I needed a personal dosimeter, the labs I worked in were transitioning to more modern electronic units with alarms and digital readouts.
I have a CDV 700 that still works, and according to the manual, is still fairly accurate measuring the check source of depleted uranium. I love old WW2 and cold war and Civil Defense stuff. As usual, another awesome video, keep up the good work man.
I have several Civil Defense detectors & dosimeters I ever have the CD-736 with the 0-20 mr. I love this stuff. My ol lady was somewhat concerned when I ordered some Cobalt-60 sources.
I have a 3 or 4 quarz dosimeters and a charger I got from a surplus dealer. These were originally used by the Finnish civil defence authorities. They all still work, only the light bulb on the charger is faulty but it has a lens you point at a strong light source to be able to set the pointer. I also have a couple of gas masks and a military surplus NBC protective suit though I don't know if it's too old to be effective. But better than nothing I guess. I really hope I won't have to start actually using them in the next few years, it does not look good in this corner of the world with our "beloved" neighbour Russia attacking Ukraine and threatening the rest of the world with nuclear weapons if they interfere almost weekly. 🥺

Appreciate your videos. It is fun to take apart things we did not have access to as children. 👍😎 - The vacuum tube is a lesson in context.

I own a cased surplus 5015/TD Radiacmeter. It probably works, but I have no idea where to get 7 replacement 6,7 Volt batteries. It also requires 2 1.3 Volt batteries, I figure a 1.5V (AA, C or D cell is close enough to that requirement), but the 6.7V batteries that would fit in the case is a problem. They are wired in separately to different circuits so I need all 7. If anyone knows of a source for a non-mercury alternative battery please advise me.
@@glennmcgurrin8397 I am not sure what a boost buck circuit is. If you know of a more modern battery that meets that voltage requirement, please share the info. I hsve considered using 2 3.6 batteries, but I am not sure the circuits will handle 7.2 volts, and of course the shape would not be the tubular one the board expects.
@Our Own Devices he must have. He passed away around 1968 1970. I'm looking for some records currently in old boxes. I'm very interested in the history of this piece. He served in the Royal Canadian Air Force and was stationed at multiples basses in North Ameeica.
Yeah I don't believe for a second they used to have little buttons of cobalt 60 they would hide around the high-school that makes no sense and would be extremely dangerous. You are pulling our legs hard with that one.
Nuclear war didn't happen in Canada, so how did they run out of measuring equipment and sent men on a sucide mission? Seems pointless to go out of the bunker every hour, knowing that the radiation would still be there. How does a machine measure "rads" if they depend on particular living tissue?
You should watch the video about the IM 108 which covers why the situation would have been a suicide mission. There are videos that cover the math involved in how radiation detectors and predictors translate their readings into what the dose for a human would be. For the record a lot of early research involved exposing sometimes unknowing people to dangerous levels of radiation.

500 Roentgens. Not great but not terrible.

Same has happened with me when I received 90Sc beta source for experiments with Radiacode 101. 🙈

Never heard of that fluorescent glass method before. Can we see it with a UV led?
Yes.
@@belyear I don't trust anything someone has to say if they're subscribed to Rebecca Watson, Sniperwolf, and Keith Olberman. Ew. very gross
@@Muonium1I upvoted your comment Muonium.

Good video but why is this only in 480p?
I really like this channel. It's very interesting & varied.
Great video, Gilles...👍
Where can I find your prior video about the RADIAC calculator?
How would they have gotten the initial 21 rad measurement? Was there another device, or did they have a standard way of estimating TEDE?
Awesome video, also-- love this series
Hey Gilles, what is going on? I miss your videos.
I have been completely swamped with work for the new aviation museum in Winnipeg. I am planning to return to producing videos shortly :).
@@CanadianMacGyver Ah, thank you! I was honestly worried a bit, you know, with this situation and all. Nice to hear you're OK.

Perhaps a boost buck circuit and a more modern standard battery?

I found a DT-60A/PD on my grandfathers' dogtags whom served during WW2. What does this mean ?
That type of dosimeter wasn't developed until after WWII; did your grandfather serve for any length of time afterward?
