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.
Recent Food and Drug Administration (FDA) approval of diagnostic and therapeutic radiopharmaceuticals and concurrent miniaturization of particle accelerators leading to improved access has fueled interest in the development of chemical transformations suitable for short-lived radioactive isotopes on the tracer scale. This …

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.
Heavier elements from the p-, d-, and f-block groups are emerging as alternative sources of radionuclides for imaging and especially radiotherapy. The exploration of the radiochemistry of niobium, erbium, terbium, astatine, and actinium will generate new knowledge about the chemistry of these 'exotic' elements.
The most important types of radioactive particles are alpha particles, beta particles, gamma rays, and X-rays. An alpha particle, α, is equivalent to a helium nucleus, (ce{_2^4He}).When an atom emits an alpha particle, the product in a new atom whose atomic number and atomic mass number are, respectively, 2 and 4 less than its unstable …
Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable).Much of radiochemistry …

tracer scale. This recent renaissance of radiochemistry is paired with new opportunities to study fundamental chemical behavior and reactivity of elements to improve their production, separation, and incorporation into bioactive molecules to generate new radiophar-maceuticals. This outlook outlines pertinent challenges in the fieldof

Radiochemistry is a scientific branch that studies the chemistry of radioactive materials and uses radioactive isotopes of the chemical elements to examine chemical reactions.. Moreover, the radiochemistry involved (as a branch of nuclear chemistry) with the production and the chemical properties of radionuclides, the use of radio chemicals, for …
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 ...

Chromium, chemical element of Group 6 (VIb) of the periodic table, a hard steel-gray metal that takes a high polish and is used in alloys to increase strength and corrosion resistance. Chromium is a relatively abundant element in Earth's crust. Its name is from the Greek for color, for the colorations of its compounds.
A cycle of studies resulted in the development of a simple technology for preparing 57Co Möss sources in a chromium matrix.
