World’s Most Dangerous Toys: Gilbert U-238 Atomic Energy Lab

General 20 128

If you thought choking hazards in toys were bad then spare a thought for American kids in the early 50′s.

Introducing the Gilbert U-238 Atomic Energy Laboratory. This toy lab set was produced by Alfred Carlton Gilbert between 1950 and 1951 and sold for $49.50US (which is equivalent to about $380 – $400US dollars today). So if you were lucky enough to have well off parents back in the day you may well have been ‘lucky’ enough to get your hands on this radioactive fun set.

There was some incentive to fork out the $50 as the set also came with a book that explained to kids how to prospect for uranium with a $10,000 prize offered by the US Government to anyone who proved successful.

The kit contained a U-239 Geiger counter, electroscope, spinthariscope (a device for observing individual nuclear disintegrations), a Wilson cloud chamber, nuclear spheres, three batteries, a “Learn How Dagwood Split the Atom” comic book. It also contained three low-level radiation sources: Alpha particles (Pb-210 and Po-210), Beta particles (Ru-106), Gamma particles (possibly Zn-65) and four Uranium-bearing ore samples.

Due to its rarity the Atomic Energy Lab is now a highly sought after collector’s item and can fetch a price of up to 100 times it’s modern day equivalent retail price.The atomic theme and box art really reminds me of Fallout 3 but that’s just me, I think I play too many computer games!

The following is an excerpt from A.C Gilbert’s autobiography titled “The Man Who Lives in Paradise”:

“The most spectacular of our new educational toys was the Gilbert Atomic Energy Laboratory. This was a top job, the result of much experimentation and hard work. We were unofficially encouraged by the government, who thought that our set would aid in public understanding of atomic energy and stress its constructive side. We had the great help of some of the country’s best nuclear physicists and worked closely with M.I.T. in it’s development.

There was nothing phony about our Atomic Energy laboratory. It was genuine, and it was also safe. We used radioactive materials in the set, but none that might conceivably prove dangerous. There was a Geiger-Mueller Counter. It was accurate; a carefully designed and manufactured instrument that could actually be used in prospecting for radioactive materials. The Atomic Energy lab also contained a cloud chamber in which the paths of alpha particles traveling at 12,000 miles a second could be seen; a spinthariscope showing the results of radioactive disintegration on a fluorescent screen; an electroscope that measured the radioactivity of different substances.

It caused quite a sensation at the Toy Fair and received a great deal of publicity. But there were difficulties. It had to be priced very high–$50.00–and even at that price we managed to lose a little money on every one sold. The Atomic Energy Lab was also the most thoroughly scientific toy we had ever produced, and only boys with a great deal of education could understand it. It was not suitable for the same age groups as our simpler chemistry and microscope sets, for instance, and you could not manufacture such a thing as a beginner’s atomic energy lab. So we had to drop this wonderful new addition to our line of educational toys–and toy has never seemed to me to be the right word to apply to such things. We adapted some of its features so that they could be added to our largest chemistry set–using the spinthariscope, some radioactive ore, and the atomic energy manual.”

The comic book that was included in the kit I have managed to source and convert into a PDF which you can download here. It is quite interesting!

I read a comment made by ‘Coyote’ on the blog.makezine.com website which I thought was appropriate.

The gift that keeps on giving…

…you tumors…

…year after year!

    Where can I buy a pellet of U238?

    This is just fascinating!

    Oh the link to the comic isn’t working. I would really like to have a gander at it.

    What about “Uranium Scope” I have one in perfect condition

    I just heard about this one over the radio and had to look it up. I wonder how the kids who had one are doing now.

    Natural Uranium is not actually all that radioactive. It mainly emits low energy alpha particles, which are stopped by human skin so are only dangerous if you inhale / swallow the source (or use it as a mistaken suppository).
    I used to work in a chemistry lab which handled natural uranium on a regular basis. I had some on my desk. When I say uranium, I mean the PURE METAL which had been refined from the ore, so it was much more radioactive than any ore-bearing rock.
    We of course had a Geiger-Muller tube counter (radiation detector) in the lab, which we pointed at every batch of uranium metal which we had delivered. It registered less radioactivity than the breeze blocks (what Americans call cinder blocks) that the lab wall was made from. Even in places where the walls had never been anywhere near any uranium – we did check the University all over once with the detector to make sure.

    In fact, only once did we try ordering natural uranium through official channels at BNFL (British Nuclear Fuels). They wanted £50 for the uranium itself (all 10 grams of it), plus £4000 for delivery in a secure, radiation shielded armoured truck with security escort. No thanks, we told them.
    So the next day, our Ph.D supervisor got his friend who works at BNFL to send him some uranium shavings from a spare (un-used) magnox reactor fuel rod, which he sent us in a jiffy bag (padded envelope to Americans) through registered post, which cost us all of £5.

    However, the cost-effective inkjet printers are usually recommended for inexpensive color
    printing. Inkjets can be used for printing text,
    but the print speed is too slow if the primary purpose of the printer is document
    printing. It prints at decent speeds, just this morning I printed a 20-page report in less
    than three minutes.

    May I simply just say what a relief to discover a person that genuinely knows what they are talking about over the internet. You definitely realize how to bring a problem to light and make it important. More and more people ought to check this out and understand this side of the story. I was surprised you’re not more popular given that you most certainly possess the gift.

    Shared hosting means that your website is placed
    on a server with many other websites. There are many web hosting
    providers who promise many things but end up giving nothing.
    This is probably one the reasons why this type of hosting is getting more popular nowadays.

    Fortunately if you discover it in time, most banks are sympathetic and
    limit your liabilities, but if it goes on for more than 60 days,
    you could be in for a nasty financial shock.
    But Thieves don’t take a break from stealing one’s identity, and one always has
    to be on guard. Take advantage also of the security and privacy options in any applications or online services before starting to use
    them.

    ll need to throw away any and all trash you find and thoroughly vacuum and shampoo the carpet
    and upholstery. Some mats are designed to prevent slippage, resulting
    that items located on the mat will stay in place. Use cotton or
    acrylic yarn to give your dish cloth extra scrubbing
    power; it’ll work equally well to clean the gunk
    off your pots and pans or to exfoliate your
    skin.

    Learn the best way to dress cakes properly from experienced cake designers who run Cake Decorating Courses throughout the
    year. Other than banana you are able to run your imagination and prepare healthy vegan cupcakes that contain carrots
    or chocolates too. You could should look for a genuinely excellent bakery for this one particular.

    It has gained notoriety because power to decrease the appearance of wrinkles in a few seconds.
    For example, if you choose to carry on vacation, you may not be in a position to hear the tour guides, or enjoy friendly conversation along with other tourists.

    My search continuing for the suitable strategy for my quick aging.
