The Egyptian Antiquities Ministry has given preliminary approval for the use of a non-invasive radar to determine whether or not Queen Nefertiti's crypt is hidden behind King Tutankhamen's tomb, according to Yahoo News.

The tomb is located in the Valley of the Kings, and is approximately 3,300-years-old.

Although preliminary approval has been granted, a security clearance for the use of the radar must still be obtained; this will likely occur within the next month.

The radar is Japanese and will be operated by an expert who will retrieve the equipment from Japan to ensure a comprehensive inspection. 

"It's not going to cause any damage to the monument," said Mouchira Moussa, a media consultant to the Antiquities Minister Mamdouh el-Damaty.

The search for Queen Nefertiti's tomb stems from a theory that Egyptologist Nicholas Reeves came up with, according to the Daily Mail. He believes that when Tutankhamen died at 19, he was rushed into the outer chamber of the tomb of Nefertiti, causing his burial to hide the existence of her tomb.

Tutankhamen's tomb was the most-intact tomb ever found in Egypt, and Reeves believes that there are clues inside that indicate that it was intended to store the remains of a queen, according to BBC News.
