Is the 60 co source of cobalt still radioactive?
The metal has the unfortunate habit of producing a fine dust, causing problems with radiation protection. The 60 Co source is useful for about 5 years but even after this point is still very radioactive, and so cobalt machines have fallen from favor in the Western world where linacs are common.
Which is the correct abbreviation for Cobalt-57?
^ Bold symbol as daughter – Daughter product is stable. ^ ( ) spin value – Indicates spin with weak assignment arguments. Cobalt-57 ( 57 Co or Co-57) is a radioactive metal that is used in medical tests; it is used as a radiolabel for vitamin B 12 uptake. It is useful for the Schilling test.
