Sure, you can look up the major wavelengths for both of these elements-that is a start-but at high concentrations, even minor wavelengths can cause interferences. In a steel sample, minor iron and chromium wavelengths will be strong, due to the high concentrations of these elements and can cause interferences.

All elements are defined by the number of protons in the nucleus. Therefore, if one changes the number of protons in the nucleus one changes which element it is. In the case of Pu239 this is exactly the case. First, a neutron is captured and then the U239 that is formed is converted to Np239 via beta decay. The Np239 beta decays and is ...

Her pioneering work in the realm of radiochemistry led to the further discovery of radioactive elements. One such element is the extremely rare radium. Major industries no longer utilize this element today because of its dangerous radioactivity, but this climacteric finding prompted the wider use of radioactive materials in the medical field.
