Swiss radiation experts and French military investigators are in Ramallah.
The team is expected to exhume the late leader's body Nov. 26, Radio France Internationale reported.
Arafat died at a French military hospital in 2004 and doctors couldn't determine the cause of death.
Many Palestinians believe he was poisoned by Israelis, RFI said.
The French government opened an official inquiry in August following a report by al-Jazeera that Arafat's personal effects showed high amounts of the lethal radioactive element polonium.
