@North Yep,!
I actually confirmed that, in the center of each walkway the radiation is less than at the surface.

The
whole
fucking
stationis uranium glazed???
That must be tens of kg of uranium!Hot damn I almost didn't want to leave
Edit:
Fuck sake there are so many armchair experts here.
NO, this is NOT dangerous!
Radiation is all around you and so far you have done just fine surviving that.
It's a nice color and an interesting historical fact, and that's all there's to it. -

A friend was visiting a glass blower in Czechia and I ended up with a care package 😍
Cubes, a shotglass and scrap for my own experiments, I'm so happy!

Also, fuck you, if you have the right of way just fucking take it.
Don't wait until I have come to a full stop to then be "nice" and wave me through.
Just fucking drive and follow the traffic rules! -

*Me, venting over being almost run over three times while biking to work this week*
Colleague:
Aha, yes, but you see, I once also saw someone on their bike not showing their best behaviour! -

So here's a fun experiment:
Nuclear Track Detectors from the hardware store!
I bought some protective sheets for welding masks which are made from a plastic called CR-39, exposed them to a radium watch face (two sheets, one on the front, one on the back in case there is some coating) and now, if I etch them, they should show tracks / tunnels where alphas hit the plastic!Now I only need a day off where I can watch a vat of 6M NaOH boil for 6-8 hours...

Another attempt and an ABSOLUTE success!
I am so happy with this, it's really simple and absolutely stunning! -

As of today I'm the proud owner of (my first!) 65 kg of low background lead and a comically large marinelli beaker 😍
Used to be a contamination meter used for food, built in the late 80s (go figure what for).I am SO happy!

I dream of the day I manage to make a clean glue joint on PMMA.
Today is not that day.
But hey, it's functional ;-)But what's the point of all this?
When a sample I'm measuring emits a beta ray there's a good chance that beta will hit the lead around it and produce Bremsstrahlung as well as characteristic x-rays, which smear the gamma spectrum and add to the background / noise.
The acrylic simply stops betas from reaching lead in the first place, plastics are great for that! -

I should finally get a vacuum pump in my flat, the alpha spectrometer would greatly appreciate it.
Also wow, that's a leaky detector!
Definitely not PIPS, probably older SSB -

Has YouTube added a way to pay for videos to appear on the front page?
Mine is currently full of 1-20 view 10-30 second videos of random companies displaying their products.
Glass cutting, tuna processing, PET bottle cutters for recycling, you name it.
What the hell. -

It amazes me how none of the replies so far are in any way related to my original question, but rather tell me to do something entirely different because that's what *they* like to do
