Jun 11, 2020 · In short, the people examining the Elephant's Foot couldn't find a better way to break off a piece of it. The team that discovered the "Elephant's Foot" were specialists from the Kurchatov Institute, the Soviet Union's premier nuclear research institution, sent to Chernobyl during the "liquidation" (i.e., clean-up) in 1986.

Aug 29, 2022 · There are photographs of folks in the same room as the foot, taken in far more recent years. Initially when authorities were trying to work out its composition and toxicity, they had to build a gimble with an AK47 attached to fire a few rounds at it, so that the super hardened chips could be collected (again by some form of gimble / trolley / doodad) to test it.

The elephants foot is a huge pile of this corium that pooled in a shape vaguely resembling an elephants foot, hence the name. At the time of/for a while after the accident it was so intensely radioactive that you couldn’t stand near it without taking a lethal radiation dose.

Aug 17, 2015 · The Elephant's Foot is also nicknamed "The closest thing to Medusa in reality" because if you're close enough to see it, you're dead from radiation poisoning without question. I don't mean to seem brash or rude in this, I just LOVE that factoid about the Elephant's foot and try to share it whenever it seems applicable, hehe.

Oct 2, 2022 · It isn't elephants foot, but backlash/hysteresis on the z-axis. Essentially, when your z-axis changes direction, it lags behind a little and has to take up slop before moving the full true amount. I fixed it by adding a second lead screw and using anti-backlash nuts.

Sep 26, 2023 · Elephant foot is the tendency of the first layer to bulge out from the rest of the model. The default Elephant foot compensation reduces the outer perimeter of the first layer by 0.15mm. This can be adjusted up or down depending on the desired outcome.

Dec 17, 2023 · A subreddit to discuss the Chernobyl Disaster that happened on the night of April 26, 1986, and the Exclusion Zone that isolates the city of Pripyat from the rest of the world.

Dec 25, 2020 · No I gave up on it. I did find that Lychee in the Pro option has feature called Compensation. From their pop-up description on the feature: Change these values to compensate for the resin shrinkage/expansion but also the elephant foot effect. Using this function will slightly affect the quality of the fine details of your 3d prints.

May 11, 2024 · The Elephant's Foot is roughly 10% uranium by mass, which is an alpha emitter, but still poses an external radiation hazard due to fission products, mainly Cs-137. As of 2015, measurements of a small piece taken from the Elephant's Foot indicated radioactivity levels of roughly 2,500 Bq (.0675 μ Ci ). [3]

Apr 18, 2020 · I tried adjusting my Z axis offset in 0.1mm increments to see if that would spread out the elephant’s foot, but no luck. It helped, but by the time I got to adjusting it by 0.4mm I was losing too much bed adhesion (models were leaving the bed) and the problem wasn’t completely mitigated. All those tests were done at 50° bed temp. See this ...
