What is promethium used in?

Answer 1

Promethium is important because it is a unique chemical element. And it is the only one other than technetium with elements that are heavier that have stable isotopes. Promethium has no stable isotopes. There is almost none of this interesting metal in the earth's crust. It is found in less than trace quantities. We know almost all of what we know about promethium from quantities we've made in the laboratory. Use the link below for more information.

Answer 2

Applications of promethium:
- beta radiation source in instruments used to measure thickness of coatings by retrodiffusion of beta radiations
- luminous paints
- atomic batteries

Answer 3

Promethium is used to measure the thickness of materials! It also shows promise as an portable X-ray generator and power source for spacecraft.

Answer 4

Promethium was identified and prepared for the first time in 1945, at Oak Ridge, USA by Jacob A. Marinsky, Lawrence E. Glendenin, Charles D.Coryell, Harold G. Richter.
