Elements that appeared to cause the greatest contamination are the isotopes of iodine and strontium although barium-140 and cesium-137 also contribute to the peril. From the issue of JULY 2, 1960 During the 1930s, many new nuclides were found, many of them by serendipity, until finally in 1939 Otto Hahn proved that a suspected radium isotope was in fact barium-140 .

Ba-135 has been used to validate the use of spinor symmetry while Ba-137 has been used in experiments regarding the theory of relativistic coupled clusters. Finally, Ba-138 has been used in studying so-called r- and s-processes in stars. Barium, chemical element, one of the alkaline-earth metals of Group 2 of the periodic table. The element is used in metallurgy, and its compounds are used in pyrotechnics, petroleum production, and radiology. Barium has a silvery white luster when freshly cut.
