are proposed to produce cobalt-60 radioactive isotope in a VVER-440 reactor. Cobalt-59 material is provided with a double gas-tight enclosure and placed inside the SZKP pipes surrounding the active zone of the reactor. The material is exposed to a thermal neutron flux, pref. for 2-4 ...
Radioactive Isotopes of Ga and Ge The radioactive germanium isotope of 1.65-day half-life has been produced by Zn(伪,n), Ga(d,2n), and Ge(n,2n) reactions, but not by deuteron bombardment of... DA Mccown,LL Woodward,ML Pool - 《Phys Rev》 被引量: 30发表: 1948年 Radioactive Trac...

THE ELIMINATION OF ADMINISTERED ZINC IN PANCREATIC JUICE, DUODENAL JUICE, AND BILE OF THE DOG AS MEASURED BY ITS RADIOACTIVE ISOTOPE (Zn65) The elimination of administered zinc in pancreatic juice, duodenal juice and bile of the dog as measured by its radioactive isotope (Zn65). J Exp Med ...
Both have the same atomic number, but different number of neutrons. The one with the two extra neutrons is radioactive and undergoes radioactive decay. The radioactive isotope of carbon was used to develop carbon dating tool, which has made the dating of various relics possible....
Radioactive barium-137m is obtained by eluting a generator comprised of the parent isotope, cesium-137, on a cobalt (II) ferrocyanide substrate.
Fenton or Fenton-like oxidation for treatment of organic radioactive wastes is a promising technology with applications to a range of organic wastes. This review details this process; exploring potential challenges, pitfalls and opportunities for industrial usage with radioactive wastes. The application ...
Both reactors and bombs produce the popularly-mentioned isotopes Iodine-131, Cs-137, and Sr-90 that populate the Press reports concerning Fukushima. I-131 has a half-life of 8.1 days, Cs-137 at 30.1 years, and Sr-90 at 29 years. As described earlier, the length of an isotope’s half...
For a shorter sample "cooling" time, a sharp line from the isotope Rb 86 is observed in the spectra. To separate unresolved peaks, ratios of the photopeaks in the standards were calculated and partial intensities computed by successive subtraction of normalized spectra. Because the calculation of...
These experimental fall-out values have been compared with the values which one calculates from the expected isotope production by cosmic radiation in various parts of the atmosphere. From such a comparison one can draw the following conclusions: 1. (1) The fall-out based on the annual ...
