The human body doesn't use einsteinium.
Fortunately, we haven't einsteinium in the body.
Einsteinium is used only in nuclear physics laboratories: for the preparation of mendelevium (and possible other super-heavy elements), calibration of an alpha spectrometer mounted on a lunar probe, etc.
There is really no use for einsteinium besides research.
Plutonium is not used in the human body.
Iridium, Einsteinium
The human body doesn't contain rutherfordium.
The appearance of einsteinium is silvery.
Einsteinium is not corrosive.
Einsteinium is not flammable.
Einsteinium is a metal.
The human body hasn't - fortunately - nobelium inside.
Einsteinium is a man-made element that is highly radioactive and extremely toxic. Exposure to even small amounts of einsteinium can be deadly due to its intense radiation levels. Therefore, it is not safe for human contact and can potentially cause fatal harm if mishandled.
