WebInstead the element's beta radiation has been used in industry to measure the thickness of materials, and the isotope promethium 147 has been used in nuclear batteries. These are long life power sources that make use of the beta radiation (which is, after all, made up of electrons, the source of an electrical current) to generate power.
WebNatural holmium ( Ho) contains one stable isotope, holmium 165. Some synthetic radioactive isotopes are known, the most stable one is holmium 163, with a half life of 4570 years. All other radioisotopes have half lives not greater than 1.117 days, and most have half lives under 3 hours.
