SOURCES OF EMERGENCY









                                     3. Loss of Control of Radioactive Materials


                                           ❖Sealed Source

                                                ➢ Failure              of       shutter            to       close          thereby             emitting


                                                     uncontrolled radiation


                                                ➢ Stolen or misplace source

                                                ➢ Unauthorized operation of radiation devices





                                           ❖Unsealed Source


                                                ➢ Emergency involve spillage and contamination of


                                                     radioactive sources onto workers, working area and

                                                     environment.


                                                ➢ Usually unsealed sources are in liquid form
