A secret security operation to remove highly radioactive nuclear material from disused medical devices in Manila, Philippines has been successfully finalized.
Radioactive material by itself, by physical law, is decaying, meaning the activity is decreasing and after a certain time, after a certain decay time, it is not usable any more for the original purpose.
Each device had to be lifted into the hot cell with a crane.
Once the sources had been removed they were placed into protective capsules within the hot cell. The capsules were slid through a passageway into a long-term storage shield. These shields were then placed into an additional metal container, secured further with a metal cage, locked and put into a long-term storage facility.
