Asbestos scare near hospital.
It was uncovered by workmen digging foundations for new buildings next to the oncology unit.
The affected area has been fenced off and a Health and Safety team will remove the white and blue asbestos.
A playground recently built by singer Kerry McFadden and her school friends for a TV show has also been cordoned off.
A hospital spokesman said the asbestos was not considered dangerous because it was soaked with water and cannot be inhaled.
Health experts said an air test found no risk of exposure.
A source close to the building project said: ``There was quite a lot of panic when bits of it were first found buried underground last week.
``But we have been told the asbestos is not as bad as it sounds and there is nothing wrong with it because it is so wet. ''
Construction workers employed by contractors Costains discovered the asbestos while digging foundations for a neuroscience unit.
