Colorist (s) Mark Bodé. Collected editions. Cobalt 60. ISBN 978-0898656770. Cobalt 60 is a science fiction comics series created by underground cartoonist Vaughn Bodē. After appearing in one story in 1968, the character lay dormant for almost 20 years. In 1984, Cobalt 60 was revived by Vaughn Bodē's son Mark Bodé and writer Larry Todd.
Cobalt-60 (60 Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. [ 3 ] [ 4 ] : 39 It is produced artificially in nuclear reactors . Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59
The truck, now contaminated by the cobalt-60, subsequently suffered a mechanical failure upon Sotelo's return from the junkyard and remained immobile near his home in Ciudad Juárez for 40 days. [4] Meanwhile, at the junkyard, the use of electromagnets for handling the scrap caused the cobalt-60 granules to spread throughout the yard.
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.

A radiation accident occurred in Samut Prakan Province, Thailand in January–February 2000. The accident happened when an insecurely stored unlicensed cobalt-60 radiation source was recovered by scrap metal collectors who, together with a scrapyard worker, subsequently dismantled the container, unknowingly exposing themselves and others nearby to ionizing radiation.
In its Sept. 2023 complaint, the Justice Department accused eBay of illegally allowing the sale of more than 343,000 aftermarket "defeat" devices that help vehicles generate more power and get ...
The deposited cobalt-60 would have a half-life of 5.27 years, decaying into 60 Ni and emitting two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall nuclear equation of the reaction is: 59 27 Co + n → 60 27 Co → 60 28 Ni + e − + gamma rays. Nickel-60 is a stable isotope and undergoes no further decays after the ...
