A new isotope of dysprosium, identified as 166Dy, has been studied. It has been shown that it is formed by thermal neutron capture in the 140 minute isomer of 165Dy, the capture cross section being about 1,200 barns. ... Another new isotope, 159Dy, has been made both by slow neutron irradiation of dysprosium and by...

Paige's Dysprosium Page ... WHAT IS DYSPROSIUM? ... The name dysprosium is derived from the Greek word "dysprositos," meaning hard to get at. In many ways this lesser known, somewhat mysterious element is true to its name. It is difficult to isolate and limited in its uses.

They discovered that radioactive Dysprosium and Rhenium do decay up to one billion times faster, when they are in what is called the hot plasma state of matter. The temperatures of the plasma state are extremely high, however, like the inside the sun or inside a hydrogen bomb blast.

Isolation: dysprosium metal is available commercially so it is not normally necessary to make it in the laboratory, which is just as well as it is difficult to isolate as the pure ... Monazite also contains thorium and ytrrium which makes handling difficult since thorium and its decomposition products are radioactive.
