The gamma spectrum misled us. But if you look closer… @Radiacode

Can a gamma spectrum be misleading?

At first glance, this sample appears to contain Americium-241 because of a peak around 32 keV. But that isn’t the full story...

In reality, this is Lanthanum-137, a radionuclide produced by irradiating Cerium-136 in a nuclear reactor. Unlike many radioactive isotopes, it decays almost exclusively by electron capture, producing virtually no characteristic gamma-ray lines!

So, how can we still identify it?

By looking BEYOND the obvious. The low-energy X-rays produced during its decay provide the clues needed to reveal the sample’s true identity...

$One of the RAREST elements with a cool property! What even is lutetium? Lutetium is the rarest naturally occurring rare-earth element and one of the last elements to be discovered. In its metallic form, it slowly reacts with oxygen in the air, which is why samples are often stored in sealed ampoules. But lutetium also has another interesting secret however… A small fraction of natural lutetium exists as Lutetium-176, a radioactive isotope with an incredibly long half-life. In fact, scientists spent decades refining its value, and it wasn’t until recently that the most precise measurements became available. Using the Radiacode 110, the radioactive side of one of the periodic table’s most overlooked elements was explored! Of course, many thanks to Simon for making this video! @simonschemiebaukasten #nuclear #radioactive #elements #chemistry #periodictable$

Potassium-40 is radioactive. Which detector detects the gamma peaks the quickest?

Test food for radiation with Radiacode and gamma spectrometry! 🦐🔬

This natural mineral contains radioactive RADIUM! ☢️

More glow = more radiation? Idk. Watch this video and find out 🤷‍♂️ lol

Uranium glass is indeed uranium glass. Confirmed by Radiacode. #radiacode #radiation #uranium
