The Zinc Of Cobalt 60 - 868 Words

COBALT-60 INTRO Cobalt-60 or also known as co-60 is one of the many isotopes of the element, Cobalt. Cobalt has 28 isotopes other than Cobalt-60, these include: Cobalt-47, Cobalt-48, Cobalt-49, Cobalt-50, Cobalt-51, Cobalt-52, Cobalt-53, Cobalt-54, Cobalt-55, Cobalt-56, Cobalt-58, Cobalt-59, Cobalt-60, Cobalt-61, Cobalt-62, Cobalt-63, Cobalt-64, Cobalt-65, Cobalt-66, Cobalt-67, Cobalt-68, Cobalt-69, Cobalt-70, Cobalt-71, Cobalt-72, Cobalt-73, Cobalt-74, Cobalt-75 and Cobalt-76 (Jefferson Lab, n.d.). Co-60 is a synthetically produced radioisotope with a half-life of 5.27 years (Centers for Disease Control and Prevention [CDC], 2014). It decays through beta particles and gamma radiation (CDC, 2005). Cobalt-60 decays into stable isotope, Nickel-60 through beta minus decay (radioactivity.eu.com, n.d.). SAFETY ISSUES Cobalt-60 can be very dangerous to human health. If ingested or inhaled, the majority of co-60 is excreted in the feces and the rest is absorbed into the blood and tissues, mainly the liver, kidneys and bones (CDC, 2014; United States Environmental Protection Agency [EPA], 2015). As co-60 is involved in ionising radiation, all co-60 that is absorbed by liver, kidneys or bone tissue can cause cancer and because it decays by gamma radiation, this results in an increased risk of cancer in comparison to other radioisotopes along with skin burns, acute radiation sickness, or death. In occasional circumstances, medical or industrial radiation sources are lost or stolenShow MoreRelatedDetecting Signs of Chemical Change1412 Words   |  6 PagesDetecting Signs of Chemical Change REAC 399 Prepared by: Elizabeth G.
