Egypt's antiquities chief Zahi Hawass said scientists began restoring King Tut's badly damaged mummy more than two years ago after it was removed briefly from its sarcophagus and placed into a CT scanner for the first time for further examination.

Much of the mummy's body is broken into 18 pieces that Mr Hawass described looked like stones that were damaged when British archaeologist Howard Carter discovered the mummy, took it from his tomb and tried to pull off his famous golden mask.

But Mr Hawass said he fears a more recent phenomenon - mass tourism - is further deteriorating Tut's mummy. Thousands of tourists visit the underground chamber every month.

'The humidity and heat caused by ... people entering the tomb and their breathing will change the mummy to a powder. The only good thing (left) in this mummy is the face. We need to preserve the face,' said Mr Hawass, who wore his signature Indiana Jones-style tan hat.

The mystery surrounding King Tutankhamun and his glittering gold tomb has entranced ancient Egypt fans since Mr Carter first discovered the hidden tomb on Nov 4, 1922, revealing a trove of fabulous gold and precious stone treasures.

Archeologists in recent years have tried to resolve lingering questions over how he died and his precise royal lineage. Several books and documentaries dedicated to the young pharaoh, who is believed to have been the 12th ruler of ancient Egypt's 18th dynasty and ascended to the throne around the age of 8, are popular around the world.

In an effort to try to solve the mysteries, scientists removed Tut's mummy from his tomb and placed it into a portable CT scanner for 15 minutes in 2005 to obtain a three-dimensional image. The scans were the first done on an Egyptian mummy.

The results did rule out that Tut was violently murdered - but stopped short of definitively concluding how he died around 1323 BC. Experts for the time though suggested that days before dying, Tut badly broke his left thigh, apparently in an accident, that may have caused a fatal infection.

The CT scan also provided the most revealing insight yet into the life of ancient Egypt's most famous king. He was well-fed, healthy, yet slightly built, standing at 170cm tall at the time of his death. The scan also showed he had the typical overbite characteristic of other kings from his family, large incisor teeth and his lower teeth were slightly misaligned.

Tourism boost
The unveiling of Tut's mummy comes amid a frenzy of international publicity for the boy king. A highly publicised museum exhibit travelling the globe drew more than 4 million people during the initial four-city American-leg of the tour. The exhibit will open later this month in London and after it will make a three-city encore tour in the US beginning with the Dallas Museum of Art.

The Egyptian tourism industry is hoping to capitalise on that interest and draw tourists to Luxor to see something they couldn't at the museum - Tut's mummy. More than 9 million tourists visited Egypt last year - up from 8.7 million the previous year, the Egyptian Tourist Authority said.

The tourists will begin viewing the mummy on Monday, Mr Hawass said.

The mummy will remain in the tomb indefinitely - unlike other Egyptian royal mummies, who are displayed in museums.

Mr John Taylor, an assistant keeper at the British Museum's department of ancient Egypt and Sudan, said tourists won't be the only ones to benefit - putting Tut on display in a climate controlled case.

'In some ways, it could be advantageous to monitor the condition to see if the mummy is stable,' he said by telephone from London.

Mr Hawass said along with putting Tut on display, experts will begin another project trying to determine the pharaoh's precise royal lineage. It is unclear if he is the son or a half brother of Akhenaten, the 'heretic' pharaoh who introduced a revolutionary form of monotheism to ancient Egypt and was the son of Amenhotep III. -- AP
