Are lanthanides dangerous?
The lanthanide compounds are moderately to highly toxic. According to animal models, the lanthanides are absorbed poorly (0.05% of the dose) in the gastrointestinal tract (Haley 1965). Following parenteral administration, the lanthanide ions form colloidal hydroxides or phosphates in blood.
What element breaks down into yttrium 90?
) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β− decay into yttrium-90, with a decay energy of 0.546 MeV. Strontium-90 has applications in medicine and industry and is an isotope of concern in fallout from nuclear weapons and nuclear accidents.
Why is SR 90 hazardous?
The harmful effects of strontium-90 are caused by the high energy effects of radiation. Since radioactive strontium is taken up into bone, the bone itself and nearby soft tissues may be damaged by radiation released over time.
How is yttrium-90 used?
Yttrium-90 is a radioactive substance. It is used in radiation therapy (radiotherapy) to treat cancer. Why do I need this treatment? Your doctors have found a tumor (or tumors) in your liver.

How is yttrium used in everyday life?
Yttrium can be used as an additive to strengthen metals, like aluminum and magnesium alloys. It’s also used to help make microwave filters, high-temperature superconductors, oxygen sensors, white LED lights, and metal-cutting lasers. Yttrium can also be used to produce fake diamonds.
How is yttrium processed?
Today, yttrium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO4), a material rich in rare earth elements. Yttrium oxide (Y2O3) and yttrium orthovanadate (YVO4) are both combined with europium to produce the red phosphor used in color televisions.

Yttrium prices dropped by 11.1% this month to $38.60 per kilogram.
How do you speak yttrium?
Here are 4 tips that should help you perfect your pronunciation of ‘yttrium’:
- Break ‘yttrium’ down into sounds: [IT] + [REE] + [UHM] – say it out loud and exaggerate the sounds until you can consistently produce them.
- Record yourself saying ‘yttrium’ in full sentences, then watch yourself and listen.
What minerals contain yttrium?
Yttrium is present in nearly all rare-earth minerals. It is obtained by mining the minerals bastnasite, fergusonite, monazite, samarskite and xenotime, which are mined in the USA, China, Australia, India and Brazil.
