The statement by the Jordan Nuclear Regulatory Commission was reported by the kingdom's newspapers Monday.
Jordanian officials have expressed worries that radioactive materials from Syria and its ally Iran could be moved across Jordan's border to Saudi Arabia and other Gulf Arab countries in case of an all-out war in Syria.
Analysts say that Syria could host ongoing, illicit nuclear weapons activity by Iran and North Korea.
The U.S. donated to Jordan 35 personal radiation detectors valued altogether at nearly $106,000 on Sunday. An embassy statement said it will curb nuclear proliferation and illicit trafficking of nuclear and radioactive materials.
