Beta Radiation Absorption Container for Radioactive mineral samples

thingiverse

Designed this container to hold a radioactive sample of Torbernite that I recently got. I tested a bunch of materials and PLA works due to it's density, but a PA12/6 GF material will be your best bet. If you can find a very dense resin that is higher than 1.7g/CC than that will work better. Unshielded, the torbernite sample emits 43.77μSv/h of beta and gamma radiation. By using the container, it was lowered to 1.3μSv/h when sampled in front of the unit and 0.96μSv/h when sampled on top. This means that the model can be safely transported as per US Health and Humans services transportation guidelines. Magnets are used in the slots to add density and are the main component for the radiation shielding. These are easily found and remove the need for lead as it's more dangerous than most small radioactive samples. The magnets are QTY10 60x10x5mm neodymium magnets, found here. https://www.amazon.com/Neodymium-Magnets-Double-Sided-Adhesive-Rare-Earth/dp/B07QWMHGHZ/ref=sr_1_10?crid=2XPS4SAPT6LF7&keywords=10x+60mm+10mm+magnets&qid=1665279916&sprefix=10x+60mm+10mm+amgnets%2Caps%2C67&sr=8-10 the inner container can be printed and wrapped in tin foil for better shielding. The unit fits a sample that is 30m in diameter inside of the smaller cap and about 33mm in the main chamber. Scale the entire system up as needed, but be aware that extra slop will be introduced in the threads. Happy printing!
