cobalt-60

A radioactive isotope of cobalt, having a half-life of 5.27 years. It formerly served as a source of beta and gamma rays in radiation units used to treat malignancies. Modern radiation units have replaced cobalt-60 by higher-energy sources, e.g., linear accelerators.

"While there was no risk to either staff or members of the public, it is important that our systems run as designed, and we take the formal letter from Natural Resources Wales seriously." Co-60 is a byproduct of nuclear reactor operations.
An RDD constructed of Co-60 would not have anywhere near the lethal capability of an RDD made from spent reactor fuel According to one estimate (Krieger, 1977), if 4.4lbs (approximately 2,000 grams) of plutonium oxide in powder form were to be dispersed in a population centre, the chances are that there would be a 100% probability of bone and lung cancer for every person within a distance of 1,800ft (550m) downwind of the release point and one per cent risk as far as 40 miles (64km) downwind.
Bq/g of Co-60 was applied at zero water potential to one end of the column.
