SHORT: CD 717 Gamma Survey Meter
HTML-код
- Опубликовано: 17 июн 2024
- Produced by the Victoreen Instrument Company starting in 1963, the CD 717 was a modified version of the ubiquitous CD 715 Gamma Survey Meter, featuring a removable ion chamber and extension cable to allow radiation readings to be taken from safely inside a fallout shelter. 100,000 were ordered by the American Office of Civil Defense (OCD), remaining in inventory until the 1980s when they were surplussed onto the civilian market.

Gilles Messier is going to be super prepared when the nuclear war apocalypse comes.
It’s amazing that there are so many of these still in unopened condition.
That's called good news.
Very cool piece of tech thanks for sharing it, Gotta love the Civil Defense logo!
We had (at least) one ff these in my GRADE SCHOOL in the 1970s, our 6th grade teacher showed it to us and explained it's use! (Pittsburgh, PA, USA) My school's basement WAS a designated fallout shelter. (Yeah, I'm getting old!).
I remember seeing those (or similar devices) when I was a kid. That was circa 1963, in elementary school. We were doing frequent "Duck and Cover" drills at the time. People like soldiers, police, and fire officers would come in with demos (?) of things that were going to 'keep us safe' if a nuke went off nearby. 🙂
Discovered your channel just a few weeks ago, got me hooked instantly. Awesome stuff man!
Interresting. Thanks for the upload and thank to the supporter sending this device in.
I have a boxed set containing a CDV700, two CDV715 and four dosimeter pens and the base to read and reset them. Great old cold war era. also have the Russian equivalent box high and low range giger counter. love these old test gear and actually like to go out uranium hunting with them.
Somewhere around here, I have an old radiation meter meant for prospecting. A very elderly man gave it to me some twenty years ago, and it uses vacuum tubes, with an 'A' and a 'B' battery. It's completely self-contained, the Geiger-Muller tube inside, and it has a should strap. It was manufactured in Winnipeg, Manitoba, Canada as I recall. I'm guessing it dates to the 1940s. When I find it I'll post some information about it. Gilles, I'd love to see you cover these devices!
I have one of those, and some of the other types!!! I also have the low scale dosemeter and several of the readers
As a kid, I was always enamored with the Civil Defense stuff, but as I grew up and learned how useless the entire idea was, and why the system was deactivated, proved the use of nukes as a last ditch effort to destroy anyone from winning a war.
Now, the only people still having such dreams of winning such a war are politicians and the oligarchy who own most of the money and can afford to have shelters made for their grave...
I've always wanted one of these.
Great videos!
My favorite OCDM meter!
Hi! glad your vids are in 1080p now, I feel like the 720p ones were holding ya back a bit. Great channel I enjoy.
720? I grew up in a 480 world. LOL
Very cool! I will keep my Radiacode 103 gamma ray spectrometer though. No need to buy one of these from Ebay. (Running to Ebay now!, LOL) Great video!!!
Why was this deleted and reuploaded? The original ID was fWYKIOJXml8.
It was first posted some time ago, then re-uploaded earlier, and now re-uploaded a second time. Something must be up. Still watching all three times because it stinks to have something happen with one of your videos.
Most often this occurs because Gilles re-edits the videos with corrections. Unfortunately, RUclips doesn't allow replacing a video, so all the comments, etc get lost. I can understand why they do this, so more nefarious types can't produce "nice" content and replace it with unacceptable content, etc. But from the viewer perspective, it does suck. You'd think with all their fancy AI that can detect spam comments and "violates community standards" then they could detect minor edits and allow replacing videos.
@@JCWren They have recently added a feature where you can type "correction" with a timestamp (similar to chapters), then RUclips automatically flashes it on the screen at the appropriate time. It's imperfect for sure, but better than what they had before, which is nothing.
Calibrated a lot of similar meters.
Wish I could get my hands on one for cheap.😅
I have the 715.
If there has been a nuclear attack then what does it mean to 'zero' this kit? Surely the background will be raised so all you are getting is a relative reading.
When you "zero" the meter, you are setting the meter dial to zero to adjust for mechanical drift. You are not adjusting for background levels.
So you have a 25 ft spool of cable, which is all well and good, but how are you supposed to get the ion chamber 25 feet away from you? Throw it? Get a volunteer?
Park it outside right after SHTF and then wait, I suppose?
was often used to run the cable down air lines to a bunker, and some bunkers had them semi permanently mounted like this.
Geiger counters do not count celists.
Hulk smash
It's Clobberin' Time❤🎉💥📛🇺🇸😎😅🐙🍄🌋🌪🦅
500 roentgen per hour, not great, not terrible
1080p videos but I’m on a beach holiday and can only watch at 480p 😂
oh.
we were so fearful in those days, weren't we.
hmmmmm. I should say our *corporate politicians* were so fearful in those days.
and decided we should be too.
(OCD has a *very* different meaning *these* days)
Nuke goes off, but you'll be safe in your bunker. Then what, there's literally nothing left outside, no cities or anything. It all seems so useless.
People think the radiation is the big issue, nope. It simply will comes down to food. As for the cities gone, then less mouths to feed. So if it does happen, make sure you have lots of can/dry food, low profile and wait for a simpler life of gardening and fishing.

The American government had a very pessimistic opinion about a nuclear attack scenario. The Warsaw Pact however had a much more optimistic approach, and when the US CD was slowly deactivated in the 1960s, the Eastern counterparts were just getting strengthened. Factories and cooperative farms were well taught how to shelter their equipment, livestock, and food from the blast or fallout was well as chemical and biological agents. The government, CD and other big companies like the railways were also required to design a communication and governing system what can function even during and after a nuclear attack. The CD also stored huge amounts of medicines and food to survive the after attack months. Overall a post-nuclear war area, based on books and directions of the CD, was survivable and livable. Not comfortable, easy and healthy on the long term, but livable. In case of Hungary the CD estimated that about 60% of the population can survive at worst and at least 40% of the industry can still function as intended for at least 1 year. This isn't bad, considering that during Able Archer exercise 50 nukes were planned to be used in Hungary.
But this was more, than 30 years ago, since then the CD is defunct in ex-WP countries, so the chances are much worse, 10% of surival rate is already too optimistic.
@@f0restmen If you talk to Russians who grew up during the Cold War, as I have, you'll find that the majority of them were terrified of nuclear war. This fear went right to the top.
Maybe in the past. But now nuclear (*thermonuclear) weapons are less powerful, because semiconductors and modern navigational systems provide much better precision and thus there are no need for dropping Tsarbomb on average city
