Question: Laboratory 3: We Used Gamma Counter Part 1: The Counting Time For Eu And Cs-137 Is 300 Sec The Activity Of The Following Radioisotopes In 10 May 2018: Eu-152 = 4.53 KB Cs-137 =3.53 KB We Need To Calculate The Activity Of Today Of Eu-152 And Cs-137 Using The Formula: 4 = Half-life: Eu-152 Half-life = 13.5 Years. Cs-137 Half-life = 30.17 Years, 942

2018-10-28 · These are difficult to study because of the high energies involved, they are sometimes very bright in "visible" light, and the fact that our atmosphere protects us from most gamma rays. To "see" these activities properly, astronomers send specialized instruments to space, so they can "see" the gamma rays from high above Earth's protective blanket of air.

12.8 days Gamma-ray energies of 152 Eu were measured with the uncertainties of 1.1–7.3 eV in the region of 290–720 keV using Ge spectrometers. To determine the 719 keV γ-ray energy of 152 Eu, we measured the 125 and 592 keV cascade γ-ray energies of 185 Os which provide the 717 keV cross-over γ-ray energy. By the use of a twelve-inch hydrogen-filled cloud chamber situated in a magnetic field, investigation has been made of the gamma-radiation from Au 198 and Eu 152. Observations on the 2.7-day period of Au 198 indicate three lines with energies 70 kv, 280 kv and 440 kv, and relative intensities 0.15, 1.0 and 1.2. The low-energy capture gamma-ray spectra of Eu/sup 152/ aud Eu/sup 154/ were examined up to an energy of 300 kev by the use of a scintillation spectrometer.
