The cobalt source has to be procured every 4 years however the facility is still using the source from 7 years ago.
Head of Cancer Unit Oncologist, Dr John Niblett says the cobalt source inside the machine is getting weak.
He says they started using the machine in 2009 and in 2012 they requested funding from the government through health department and are yet to receive any positive response.
Niblett says the department is still looking for funds.
This means the number of patients they treat every day will decrease.
