An interesting new "Tested" got released today. Adam obtains a titanium spehere and builds a model core and the transportation box. I'm sure this will be a popular video for redditors here.
I understand that Europium-152 decays primarily (72.1%) via Electron Capture, which produces Samarium-152 that has an excited nucleus. The Samarium-152 then emits a gamma to drop to its ground state. I'm not finding any decay chain charts that show this gamma emission, which is confusing to me. (I also understand some charts leave out gamma under some circumstances.)
My question is, does Electron Capture usually produce daughters with excited nuclei, which then emit a gamma, so it isn't normally listed? I must have missed that correlation in my studies if that is the case.
Thanks.
I asked Spectrum Technologies for a quote on some 0.1uCurie sources, but put off the purchase. I modified my request and got a new quote yesterday. These sources have go up $20 each, from $45 to $65, and shipping is up $5 more too.
Disappointed that my order will now $65 more than it was last month.
I am interested in glazed decorative tiles from around 1900 through the 1930s. I'm looking for buildings, (commercial, governmental, schools, parks, private walls along public sidwalks, etc.) that were built around that timeframe which have glazed decorative tiles on them.
If anyone knows of any tiles on buildings of this age around town, I'd be interested in hearing suggestions on where to look.

My Alphahound AB+G arrived a few days ago, and I have been having some fun with it. I soon realized there are a few display modes where I would like the unit to be standing upright to more easily see the display. Radview has the stl for the included dust cover on their website. I downloaded that, modified it slightly so I could plug it in while it is in the cradle, and added the base you see here. I uploaded this remix on to thingiverse if anyone would like to print one for themselves. Just search for alphahound. I have designed a handle and a separate mount for a cane I occasionally use. I'll post those too if there is any interest. My printer is wearing out, so this print is a bit rougher than I would like.
A comment in a recent post mirrored a question I have in my mind, so I thought upgrading it to a group question would be informative for beginners like me.
I have a couple of specimens that are low activity, a few thousand cpm & 25k cpm. When I do handle them, I follow those suggestions outlined in "Here Be Dragons"; keeping the specimens contained, gloves, limited time, distance, proper hygiene afterward, etc.
Often, more attractive specimens have higher to vastly higher activity. Other than increasing distance (the use of tongs, not bringing radioactive specimens inside the home to avoid any chance of contamination there) and reduced exposure time, are there any additiona steps or procedures that newer collectors should consider before buy highly active specimens?
As I mentioned earler, assume that the collector is already following the recommendations for storing and displaying these materials. I'm curious about any additional steps that should be taken to remain safe with high activity specimens.
Thanks!
