Hahahah…it does.

I thought it, you said it before me.

Their manager was a lawyer, and their first album was called Industrial Disease ...

Just pitch the 🍌

Since I was 8, I sometimes listened to REM band. However the first meaning I learned of that abbreviation is Radiation Equivalent in Men not Rapid Eye Movement.

Me too! Missed verification of decon with meter readings on peeled banana and washed cup.

I saw some experiments with respirators on Russian YT channel Mr Drimogemon.

In one of the lab experiments at the uni, they made us measure the radon collected inside some air filters they put into the basement of the lab. We had the use of a germanium detector and we first measured them before putting them in the basement, then after they were left there for 4 days. With germanium's energy sensitivity at LN2 temperatures you could see all the lines of the daughter nuclei extremely clearly

I'm looking forward to doing them...should be fun. They will take a bit more work than sticking stuff into a Revigator.

Thanks. Glad you are enjoying the content.

Its a video I'm planning on doing as a couple people have asked the same question. Hopefully I'll have time to do it soon.

I used to have a steel cabinet with a lock sitting outside the garage door for storage of stuff like this.

I might do a follow up video.

That would be an interesting idea. Radon isolation is kind of tough with radon having such a short half-life. I would think it would be much easier to collect the Lead-210.

Glad you enjoy them.

CPM and CPS are related to particular type of the detector (GM tube, PMT etc.). The simplest way how to use them is to compare them with background reading. Reading in CPM by itself means nothing, it must be always related to particular detector. If you want to convert it into dosimetric quantity (like equivalent dose rate in Sv/h), you must know the detector characteristics and properties of the radiation detected. Many people ignore that GM tubes detect multiple radiation types at once and they seek for magic "cpm to usv/h ratio" which can always be stipulated but for one particular situation only, without proper shielding and compensation of energy response it's nonsense to use it for wide ranges of energies and several types of radiation being detected simultaneously.

@@Ales.2000 In practical use i se cps/cpm beeing used to find contamination to detemind how equipment is handled or disposed of after use. So as you say it shows above background, clearly indicating contamination and that is a good thing. But not easy to translate and compare in my brain when i am used to Sv/h from sources with much higher activity and mostly using GM tubes on gamma radiation as sources are shielded :) So not easy for Drew to make the comparison on video either.

Sieverts and others are good for finding things in a volume of a substance. Smaller read outs. Cpm is an average of the combined exposure. Depending on the counters sensitive ranges for whatever type. Another would be joules the amount of energy those charged particles emit upon hitting something. The ticks and beeps you hear. Both are direct exposure over a given surface area. Used to calculate safe exposure times vs the amount contained in a shielded liquid like water. Sievert looks like a smaller statistically as it is usually used to find the smallest amount in something. That’s been the reason it’s been used socially vs cpm etc. It’s less alarming to those that don’t understand the measure of units. If your concerns are you immediate exposure rates and the level of harm your being subjected to you use cpm. A standardized unit based on real world data. And military training uses a graph based on direct studies. At what point does ionizing radiation and “hard” radiation pose an observable effect on a living being. Answer 300cpm and no exposure is safe. Most especially dust and particles.

@@pazsion What on earth are you talking about? For the protection of uninformed commenters I will simply recommend that everyone disregard this characterization of the use of Sieverts and cpm readings...

I think that scan uses Tc-99m, which puts out a lot of gamma. I was able to detect my family member that had a similar scan when they walked into the house using my Radiacode 101.

That would be fun…in a sealed glove box.

@@RadioactiveDrew Also, we talked about finding uranium in nature in the comments a while ago. And you inspired me to check the old uranium mine again, where I previously thought there's nothing to find. And there was actually a spot and got plenty of ore😁 So thank you very much for the inspiration to go out there again and look.

Glad you liked it.

A cloud chamber is on my list of things to build.

@@RadioactiveDrew awesome!!! Can't wait to see

Very true...but an alpha / neutron reaction would be far more accessible.

I'm going to do a video on the Revigator getting a little more into the history behind it.

I plan on making a video just about the Revigator and explaining what they were trying to do with all that.

I’ll make sure to share that when I do a video about the Revigator.

The contamination was suspended in the air...so even if a side is touching the carnotite layer it wouldn't be as contaminated as the sides facing up.

I have some potassium chloride salt substitute that I got at the store. Its just a little bit radioactive.

A tablespoon of it evenly spread usually gives out about 500 CPM (LND 7317 no energy compensation) which is the highest count I could ever get so far. The enrichment of potassium is impossible without highly sophisticated equipment and as long as the proportion of K-40 in potassium intake remains the same, the ionizing radiation exposure is not increased.

I plan on doing something like this.

I use a 0.0057 conversion for mine so 80,000 cpm is roughly equal to 400 uSV / h, but then again cpm is realative to the detector so it's very hard to gauge unless you compare it to the background radiation.

I'll have to check. Those would mainly be seeing gamma radiation...very few betas and no alphas.

@@RadioactiveDrew Yes that way we can estimate the radium activity

There is no carnotite powder in the Revigator. The material inside the container is like a concrete and doesn't come off easily.

Thank god I am not alone, it's just common sense. Seeing that cup go in made my stomach twist, his brain tumor must be pushing on something important.

@@discoverbasic5760 I mean what he's doing isn't really dangerous, but what annoys me is the completely unnecessary risk taking, it sets a bad example

I've seen those cones before...mainly at the Nuclear Science and History Museum and some other places. Its amazing what you can find at an antique shop.

They can be found. Finding them out in an antique shop might be pretty difficult. When I found mine I didn't even know what it was.

That’s what I was thinking about doing. There are a couple papers out there about neutron maximization in RaBe reactions that deal with different configurations and how to configure HDPE to get the neutrons down to a thermal speed. Ideally I would want to get some beryllium machined to a particular configuration but beryllium can be a bit hazardous to machine down. I’m sure some people can do it.

The idea behind the Revigator was so people could have the same type of water found at hot springs that were also radioactive and had radon infused.

You could expose that thorium nitrate to x-rays but it shouldn't do anything to it. If you wanted to transmute it into another isotope you need neutrons.

@@RadioactiveDrew thank you

Its hard to do because it doesn't translate straight across. It really depends on what you are detecting. This Reviator gives off a lot of alpha and beta radiation with some gamma...so counts per minute makes a bit more sense. If it was something like Cs-137 or Co-60 then Sieverts would make a bit more sense to use. Still even in those cases I still like seeing counts as that's the raw data before a dose conversion happens.

The t-shirts are ones I make and sell on my site uraniumstore.com . As far as the button up goes I believe I’ve gotten those ones from REI.

I had to use the Ludlum 14C to get the reading down in the Revigator. Really hard to show the reading from the Radeye when its down in the container.

Uranium glass is much easier to find.

I don't think there would be enough radiation to effect it. But maybe I'll have to try it out.

That would be fun.

Never...but I'm sure there's a list with my name on it.

Air filters in homes are always fun to check.

Yeah...it was during a time where there wasn't much regulation in food or drugs.

It was the 1920's...they thought a lot of stuff was good for you.

@@RadioactiveDrew Bayer made and sold radium pills. I've actually seen the bottle. How insane is that?

@@RevMikeBlack wish I could say that surprises me.

I plan to show otherwise.

One of those millicurie Polonium sources with Beryllium infront of it plus some HDPE blocks is all you need

I think it might work, not only beta radiation but alpha as well. However it might be rather rare thing to find. Few years ago we had our lightning rod replaced so I checked it with Geiger counter (using LND-712 tube) and found no activity. I'm from the Czech Republic, it may be different elsewhere.

@@Ales.2000 Thanks, that's interesting. Yeah, I thought about alpha emitters as well, but I have heard that the alpha particles only manage to move a few centimetres in air .. and if so, the ionized area would exist, as you indicate, but be quite small.

I’ve heard of these and they seem super rare to find. But I’m planning to test this idea out…if these lightning rods worked like they said they did.

@@RadioactiveDrew BTW I posted the link to the article in a separate comment, which got blocked (as I suspected), but maybe it's visible for you as the channel owner.

The problem with that is putting a beryllium canister in the Revigator is that only a small amount of the alpha particles are going to hit it and create neutrons...some alphas from radon and the other daughters might interact with the beryllium. The other problem is that beryllium is also a neutron reflector. So it would be better to have a strong alpha source next to or mixed with beryllium and then some HDPE plastic to slow down the neutrons so they would have a better chance to hit whatever your target was.

In my opinion, beryllium is too expensive and poisonous, maybe some aluminium might be used, Marie and Pierre Curie inserted polonium into aluminium flask and found out it became radioactive. The reason was that alpha particles reacted with Al-27 to form P-30 (β+, T½=2.5min) and neutron. So some aluminium foil might also perform well if the alpha emission it is subjected to is sufficient.

I don’t think the source of radiation is strong enough. But you never know until you try.

I’m working on video dealing with this.

I believe you are thinking of the Radithor drink that they use to sell back in the 20's and 30's. Apparently that drink had radium dissolved in it and Eben Byers drank an insane amount of them.

@@RadioactiveDrew Had to fact check and you are correct, it was Ebenezer Byers. He was drinking water bottles with radium to the point his jaw looked like the radium women’s jaws or worse. Ever read the book Naked to the Bone. It’s the history of X-Rays from discovery to CAT scanners. Book is well written.

I’ll have to check out that book. Thanks for the recommendation.

@@RadioactiveDrew Is a trip to California in your future? If so, any interest in visiting The Rad Lab now Lawrence Berkeley National Laboratory? This is where several of the transuranium atoms were first synthesized and home of the first first cyclotron.

I would love to go there. That area is a huge piece of nuclear history.

The ones made with Thorium? Yes.

@@mjrippe Yes. Just like the Revigator was back then, there is still radioactive quackery going on today.

That would be cool to have. Usually I use a filter and distance to figure out different types of radiation.

Yes, they thought it was a good thing. I'm going to do a video going into detail about this item.

The t-shirt is one of the designs I made and sell it on my site uraniumstore.com

@@RadioactiveDrew sweet!!! Found it, ordering now 🤠 that's a sick design and description! Blacksmiths of modernity! Definitely a metal band name 😁

I have that AirThings radon monitor in the house. I've pushed mine up to around 320 pCi/L by sticking it in a case with some radium doped compasses. It was fine after a couple days.

@@RadioactiveDrew omfg haha ☢🤣 do a video!

@@Muonium1 I'm hoping to do something like this...maybe pushing it to its limit. Hopefully without breaking it.

@@RadioactiveDrew after extensively researching its construction and operation through patents and teardown images, I'd say there's....really nothing to actually break! It's quite a remarkable all solid-state system, consisting of little more than a single photodiode detector chip the size of a fingernail enclosed in a metallized plastic can charged to 10V. That's it. It uses pulse height discrimination to count only the alpha hits on the photodiode and the can is constructed to allow only Rn to diffuse into it, eliminating ingress of external Rn progeny, so it really is insensitive to anything but actual Rn decays inside the sample volume. It doesn't seem to care at all about ambient gamma or betas.

@@Muonium1 I've heard of some people saturating their radon detectors and they are never able to get them back to reading normal levels. I haven't experienced anything like this yet but I'm hoping to push that AirThings to its limit.

True…I could have shown how both the cup and the banana were no longer radioactive after 9 hours as well.

Thanks for the recommendation. I already have an AirThings radon monitor but I'll take a look at this other one.

Just checked it out and it only goes up to 99 pCi/L. The AirThings goes up to 500 pCi/L...which I have needed in my testing.

@@RadioactiveDrew well air things might be alright for measuring radon inside the revigator but I would still recommend the eco cube for monitoring household levels as it is far more accurate.

@@mr.microcuries2078 where may I view data attesting to the relative inferior levels of the corentium instrument's accuracy?

That's a good question. I believe people were contaminated to a degree after drinking the water from this jar. I need to do some tests to see how much contamination it was.

No problem.

Just good old fashioned luck.

The radium girls were ingesting a lot of radium because of using their mouths to make a point with their paint brushes. Someone lining the inside of a bunch of Revigators would be exposed to a decent amount of radiation but most of it would be external exposure I would imagine.

I don't know how it is made so that carnotite adheres to the ceramics, but remember, radium girls were working with a paint containing some radium salt. Although carnotite contains radium as uranium decays, chemically it's compound of uranium, potassium uranyl vanadate trihydrate.

@Ales2000 and that's bad...right?

@@joebeach7759 I just wanted to say that manufacturing of the revigator was much less harmful than painting dials with Ra-containing paint.

@@Ales.2000 I was just making a joke

This might increase your risk of cancer if you were drinking out of it all the time. People inadvertently drink radon infused ground water quite a bit.

@@RadioactiveDrewit is really shocking to have a household ware radioactive. Donno how can they are allowed. Innocent people might use it daily.

@@RadioactiveDrewthanks for the info. Informative to know regular healthy people can have resistance and only it harms when consistency built up.

Right now I keep it in my office because I’m working on some videos that involve it. But usually it lives in the garage.

I used the Ludlum Model 14C in the beginning because its easier to show the reading down in the Revigator using that than with the Radeye B20.

For some reason I thought the UK had something like this back in the 1920’s. I’ll have to look into it further.

@@RadioactiveDrew 👍👍👍
