Interesting facts

➤ Gadolinium was named in honor of scientist Johan Gadolin, a first in the history of science.

➤ The 157Gd isotope is a "record holder" for thermal neutron capture, which allows for control of the nuclear chain process.

➤ It has high ferromagnetic properties.

➤ When the compound is demagnetized, it cools to a temperature below absolute zero by 0.001°.

➤ Luminescence with Gd oxysulfide produces contrasting X-ray images.
