Strong in 1909 using a photographic emulsion. In 1930 L.V. Mysovsky and R.A. Eichelberger, using a Wilson camera, showed that this radioactivity is accompanied by the emission of beta particles. Later it was shown that it is due to the beta decay of the natural isotope of rubidium. & Nbsp; </div> <div> Although in a number of applications rubidium is inferior to cesium, this rare alkali metal plays an important role in modern technologies. The following main areas of application of rubidium can be noted: catalysis, electronic industry, special optics, nuclear industry, medicine. </div> <div>   </div>
