Queensland Government orders a probe into x-rays.
An investigation is underway after revelations almost 50,000 x-rays taken at public hospitals on the Gold Coast have not been properly checked.
The investigation will examine what Health Minister Lawrence Springborg has called a long-running failure of a system designed to pick up undiagnosed medical conditions.
The Gold Coast Hospital and Health Service Board says it is aware of at least two patients who suffered adverse effects as a result of the failure.
It said it was aware there were problems with the checking procedures, but the extent of it did not become clear until late last week.
