protactinium

If the protactinium remains in the reactor, small amounts of U-232 are also produced.

Protactinium is a chemical element with the symbol Pa and atomic number 91.

In all these organs, protactinium promotes cancer via its radioactivity.

The name was shortened to Protactinium in 1949.

Protactinium is one of the rarest and most expensive naturally occurring elements.

Protactinium is paramagnetic and no magnetic transitions are known for it at any temperature.

Proliferation risk from protactinium separation for some specific designs.

The rocks are rich in deposits of protactinium.

Protactinium in the body tends to accumulate in the kidneys and bones.

Because of this possibility, commercial power reactors may have to be designed without separation of protactinium.

As actinium, the distribution of protactinium follows that of U.

In an earlier collaboration with Hahn, she had independently discovered a new chemical element (called protactinium).

The coordination is the same in protactinium(V) chloride, but the color is yellow.

Protactinium is both toxic and highly radioactive.

Protactinium is more abundant (10%) in the Earth's crust than actinium.

Also a harder neutron spectrum helps to achieve acceptable breeding without protactinium isolation.

Due to its scarcity, high radioactivity and toxicity, there are currently no uses for protactinium outside of basic research.

Protactinium was possibly isolated in 1900 by William Crookes.

For many years, this was the world's only significant supply of protactinium, which was provided to various laboratories for scientific studies.

The estimated shear modulus of protactinium is similar to that of titanium.

Protactinium is a metal with silvery-gray luster that is preserved for some time in air.

In hydrides and nitrides, protactinium has a low oxidation state of about +3.

The atomic number of protactinium, an actinide.

Before the advent of nuclear reactors, protactinium was separated for scientific experiments from uranium ores.

Protactinium forms mixed binary oxides with various metals.
