How Much Radiation Was I Exposed Too

In this video I see how much radiation I was exposed to when I made the video about the radium smoke detector and what that radium source looks like under an alpha radiation viewing screen.

Link to the eBay seller that makes the Alpha Viewing Screens. He currently doesn't have any for sale but hopefully that will change soon.

I like how your camera's image sensor picked up radiation noise as well, when you got it close to the post.

Great video, and cool to see the blue glow to visualize the "spray pattern." It's not always necessarily equal in all directions.

That thing is shedding so much radon progeny all over your table and your hands from touching the detector. Every time I handle anything with more then 2 mCi of RaSO4 or any of the other ionic compounds of Radium my gloved hands become contaminated no matter how much scrubbing I do I can still detect contamination with my SEI Inspector USB. I have a DP-63a Russian dosimeter that has a RaSO4/Cl, Br scale in it that is extremely HOT. I’m not sure how much Ra is present in mCi but it’s definitely more then 2mCi that’s for sure. I also have one of the F3/F5 Pyrotronic industrial smoke detectors as well. It’s the 80mCi ver. I love your videos my friend! Looking forward to seeing more of your content.

This is presently the best video of a spinthariscope doing its thing anywhere in existence.

Thank you for the updated video. I too was concerned and wondering how much radiation you received making the video for us.

This video was really cool, i just watched the first one with the smoke detector and left wondering how much radiation you'd experienced! The visualisation on that Alpha Radiation viewer, it was both exactly what i expected and really impressive at the same time! And you could see some of the particle damage in the camera too!

as of Jan 2023 That seller has them cards. he also has some voltage regulator 900V Zenner unit for GM Tubes. I got a Russian GM tube in home made counter. just a HV source adj 900V threw a resistor to GM tube and a HV blocking cap to LM 386 audio amp to small speaker. simple but works to detect radiation . runs on 6V battery. made it years ago as a electronics project. from last night lots of GM tubes can be found on eBay and amazon .I may add VU meter to my unit. the clicks get louder as Radiation increases. I bult it with Radio shack parts years ago and GM tube from eBay . Thank you for the link.

Some of those old smoke detectors actually had plutonium in them back in the day, also it's worth noting that smoke detector heads were often tossed into attics and under floors on refurbishments over the years or just thrown into builders skips of demolition rubble or the trash can...


I've noticed that they have very quickly and very quietly removed sealed source detectors out of the market and they are almost all fully optical detectors on sale now, this had happened in the last 4 years or so here in the UK and I imagine in the USA as well 🤔

Excellent video with good information. United Nuclear sells small units for viewing alpha radiation.

9:13 — Forget the alpha detecting film, I see those white specks appearing on your camera sensor! That's terrifying.

[Bluescout]

Cool video in 40 years of using scintillation detectors. It was neat seeing it inaction so to speak

[SigEpVet]

You didn't discuss the exposure from those portions of the previous video where you had removed the cap, taken out that post, or opened the can with the screen in it. I would surmise that it would have been a lot more than you video discussed for emissions from outside and sealed.

The alpha radiation concerns me when I see someone holding such a device and it's radioactive core directly in his fingers. I wonder how effective gloves are and I am wondering which kind of gloves had been used? Thanks for the video. It is a very interesting presentation, especially with the follow up.

[plutoniumiscool]

Great video, you should try to get one of those plutonium smoke detectors, but they might be illegal in the US i think.

I just picked up a westclox alarm clock that according to my Geiger counter if measured at the face is putting out about 42 usv/hr. Crazy that these were on peoples nightstands.

[marcwashburn]

Nice....love that alpha radiation viewing screen! please post when you have a link to purchase one :)

[lxOFWGKTAxl]

You should make or buy a radiation cloud chamber! I would love to see how active those are in it!

[MinSredMash]

Have you considered that the beta "overcoming" the filter is actually creating bremsstrahlung X-rays?

[jordanch]

GEOElectronics is a great source. Especially for CDV-700 repair items.

This guy is going end up like the Boy Scout who turned his parents back yard shed into a superfund site collecting smoke detectors to build a reactor lololol. That alpha viewer is pretty freakin cool though. My new favorite thing to do is make my vegan friends watch the Monsanto video and hear the wheels start spinning trying to argue how bad eating animals is
