Cobalt 60. Co60 is a common calibration source found in many laboratories, it is synthetically produced by neutron activation of Co59, and has a half life of 5.27 years. The gamma spectrum has two significant peaks, one at 1173.2 KeV and another at 1332.5 KeV. Most good scintillation detectors should have adequate resolution to separate the two peaks
Cobalt 60 gamma spectrum: The excited states of nickel 60 are reached when cobalt 60, an isotope widely used in medicine, undergoes beta decay. On the nucleus's path to the ground state, it emits a number of gamma rays to expend the extra energy it possesses

Cobalt-60, 60Co, is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59Co. Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be.
60 Co decays to 60 Ni with a half-life of T ½ = 1925.5 d. The decay of a 60 Co nucleus releases one electron with 317.9 keV energy and two gamma quanta with energies of 1.173 MeV and 1.332 MeV. The 60 Co radiation sources used in the irradiation facility usually consist of activated discs or small pellets of metallic cobalt welded into cylindrical stainless steel containers
Kobalt-60 (symbool: 60 Co) is een relatief onstabiele radioactieve isotoop van kobalt.. Kobalt-60 ontstaat onder meer bij het radioactief verval van ijzer-60.. Radioactief verval. Kobalt-60 vervalt voor 100% via β −-verval tot de stabiele isotoop nikkel-60: + − + De halveringstijd van dit verval bedraagt ongeveer 5,27 jaar

Cesium-137 and cobalt-60 isotopes were obtained from the Oak Ridge National Laboratory for use with the chamber. The cesium isotope emits a gamma ray of 0.6614 Mev [3], and cobalt-60 emits 2 quanta in cascade per disintegration with energies of 1.1715 and 1.3316 Mev [4]. The activities of th

Cobalt 60 has been largely replaced by other Iridium-192 in high dose rate brachytherapy and by linear accelerators in external beam radiation therapy. Because of it's high activity and simple gamma spectrum, it is used in the calibration of radiation detectors
3.2 Background Spectrum The Co-60 spectrum needs to be separated from the background by subtraction in order to gain the net counts. The analysis software subtracts the count rate of the background radiations, from the count rate for source+background, giving us the net counts for each energy channel
Cobalt-60 decays, with a half-life of 5.3 years, to the element nickel-60 by the emission of a 0.32 MeV beta particle. The nickel-60 daughter nuclide is formed at an excited energy state, and loses this energy immediately with the emission of two gamma rays of energies 1.17 and 1.33 MeV, settling at a stable nuclear state

um, beta particles can penetrate the dead skin layer, potentially causing burns. They can pose a serious direct or external radiation threat and can be lethal depending on the amount received. The
cobalt 60 source, where the diameter of the radiation beam was 25 cm, and the gamma dose rate 4 r per minute. Exposure times of about 9 minutes were used. The cobalt source was about 10 mm in diameter, perpendicular to the centre line of the beam, and was enclosed in a container of' stainless steel The invention of the cobalt-60 teletherapy machine by Harald E. Johns in Canada in the early 1950s provided a tremendous boost in the quest for higher photon energies and placed the cobalt unit at the forefront of radiotherapy be produced, resulting in a continuous photon spectrum The gamma spectrum from Cobalt 60 decay has been investigated with a 40 cc Ge(Li) detector. A peak at 822 keV is shown to be not a gamma transition but a single escape peak and an upper limit of 10 is given to the branching ratio of the 2158 keV level

We placed Cobalt 60 and Sodium 22 in front of the detector, in order to determine if all of the previous peaks were independently identifiable in a joint sample. The test proved a success; we were able to identify all of the peaks of both the Sodium and the Cobalt samples Kobalt-60-Spektrum. Das Gammaspektrum im Beispiel gehört zu Cobalt-60, gemessen mit dem NaI (Tl) -Szintillationsdetektor und dem HPGe-Detektor. Kobalt-60-Spektrum Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics.. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced Cobalt found in: Cobalt Sulfate, Practical, Cobalt Metal, 400 Mesh, Powder, Cobalt Oxide, Black, Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumpt. 3017-60-5.

In de natuur komt één stabiele isotoop (kobalt-59) voor en een groot aantal (ruim 20) radioactieve, waarvan kobalt-60 de langste halveringstijd heeft. Het vervallen van kobalt-60 naar het stabiele nikkel-60 is de belangrijkste reden om een kerncentrale na uitgebruikname zo'n 20 tot 150 jaar te laten 'afkoelen' alvorens te beginnen met de ontmanteling
SPEC Cobalt-60 Sources Cobalt-60 is widely used throughout the world for demanding industrial field radiography applications.
