Our spiciest, most experimental setup by far at the moment.

And yes, I can still measure increased radiation in the lab on the other side of that wall. It's a good thing nobody is currently actively working in that one!

@StripeyYena what kind of source is this?

@fesix Co-57 in a Rh matrix.

@StripeyYena @fesix sooo... a ton of low energy gammas, some betas that probably won't make it out of the matrix at all and a bunch of fluorescence?

Sounds like a fun source, many peaks distributed over not that much energy. I guess that explains how you can get away with just a few mm of lead

@gigabecquerel @fesix Yes, though we "sadly" only use the 14.4keV photons in transmission, the rest is just byproduct, with the higher energy ones of course being able to go through a bit more shielding. But the outside view is a bit deceptive, the driving units usually have lead collimators that are a few centimeters thick, and there are three or four layers of the thinner sheets stacked under the visible outer one.
