"Good god! Do you realize what you've done?"
"Not quite."
"You've duplicated the pope! Except the new one is a bit heavier."
"True. That's because he is an isopope."

Zur IEA:

Ups. Eigentor.
Ich wollte unabhängige, nicht lobbyismusgesteuerte Quellen. Kannst du nicht liefern.
Und zur geologischen Stabilität ohne Wassereinbruch usw. für Jahrtausende:
Gorleben macht vor, wie gut das funktioniert.
Garantieren kann das eh keiner.
Insofern bei deinen "Quellen': Traue keiner Statistik, die du nicht selbst gefälscht hast.
Zum "an Uran lecken":
In der Zerfallsreihe entsteht mitnichten nur leicht abschirmbare #Alphastrahlung. Auch die #Spaltprodukte zerfallen auch mitunter mit Betazerfällen, also #Betastrahlung.
#Gammastrahlung tritt als Begleiterscheinung auf.
In den #Zerfallsreihen entstehen auch #Plutonium #Isotope
Also ganz ungefährlich das #Uran und seine Spalt- und Zerfallsprodukte.
Und Paracelsus: Ja. Nutzt denen in der Nähe aber dann nix, wenn, wahrscheinlich lange Zeit unbemerkt, massiv radioaktive Stoffe aus dem Atommülllager in deren Trinkwasser eingetragen werden.
Du bist schlicht Atomlobbyist, vermutlich sogar beruflich in einer Interessensbranche tätig, der, so wie #Klimawandelleugner auch, tatsächlich glaubt, er sitzt in einem anderen Boot, wenn es zum #GAU kommt.

Secondly, it wasn't Frederick Soddy who introduced the word at the dinner party. Instead it was proposed to him by his cousin, the physician Margaret Todd (one of the first women to obtain a medical degree from the Edinburgh School of Medicinw for Women). Soddy then introduced the word to the rest of the world in a 1913 paper in the scientific journal Nature.
I love that Glasgow University has a plaque on one of its buildings marking the birthplace of the word Isotope. Unfortunately, it has two rather major errors. Firstly, the dinner party where the word was first introduced didn't happen in 1913, but sometime between 1909 and 1912.

A Seismic Shift – Earth’s Plate Tectonics Recently Underwent a Fundamental Change
Earth’s abundant water, life, and unique plate tectonics have shaped its history, however, a new study suggests that plate tectonics may be a recent phenomenon with the mantle previously stratified, possibly hiding undisturbed primordial material.

One of the two remaining classical town houses on University Gardens in Glasgow designed by J.J. Burnet and built in 1882.
These buildings are famous of two things:
1. Having the cheapest beer on campus (when they housed the Research Club).
2. Being the birthplace the word 'Isotope' in 1913.
I don't think these two claims to fame are related in any way (but then again, who knows!).

Scientist's life is: hardly being able to sleep from excitement. This week we kicked off not one, but TWO new projects with two new team members. The second one will be experimental #diagenesis in #foraminifera, which are widely used for #climate reconstructions. They record the #isotope composition of the seawater in which they lived, but that composition may be altered after their death - we will try to reproduce this experimentally in the lab as part of a nessc.nl project. I started a #palaeontology BSc course 
by incorporating analytical methods and teaching students documentation of their analyses by using #RMarkdown. It is an attempt to change the perception of #palaeontology from descriptive and exploratory to a more hypothetico-deductive and quantitative field. And I finished at the Uni of Leicester 
with the big honour of examining a PhD candidate who epitomized this approach by establishing a quantitative proxy for the trophic level of #conodonts and possibly any #invertebrates with dental tools. And that's just the highlights. It's a big privilege to be a scientist.
Having some difficulties coming up with anything visual that represents #Isotope #Archaeology #IsoArcH..
Already sent over pictures of basic lab life, #Isoscapes, plots with data... What else exciting is there?
Might have to resort to cat pictures instead..
I’m just getting started with Mastodon so here’s an #introduction.
Mature PhD #archaeology researcher working with Bronze Age animal bones from #Lincolnshire to learn about diet and mobility, specifically seasonal movement for grazing.
Based in Classics & Archaeology, University of Nottingham, with links to University of Leicester and British Geological Survey.
Interested in #isotope analysis, #zooarchaeology, #theory. Husband, Dad to 2 wonderful people, #classicalmusic geek, son of #Tyneside.
#Welcome #NewHere
I'm Daniel, an analytical (geo)chemist and lab manager at #CAU university of #Kiel - my scientific interests are the technological advancement of in-situ analytical routines, so that #stable #isotope and #element #ratios can be used as a toolbox to probe natural processes (#uptake of beneficial elements in plants) and reconstruct the past (e.g. as #climate #proxy )

Hello all, my name is Martin and I am new to Mastondon. By day I am a medical doctor working in the #NHS and by night I am researching the #history of #anatomy and #anatomicalstudy in Britain. I’m writing a book about it because it’s such a truly incredible (and at times almost unbelievable) story. As part of my research I have had so much help from kind experts in the fields of #osteology #isotope analysis, and #radiocarbon dating. I’m amazed at the kindness and generosity experts have shown me and I am thrilled to be in the edges of such a fabulous scientific community. Already this platform seems gentler than the other one and I look forward to meeting lots of new and interesting people… and I might ask some silly questions!
