National Committee for the Certification of Radiation Protection Officer Sales refer to all steps beginning with the order of the product to its delivery, and involve its installation and commissioning. Vendors or companies that deal with sales must ensure the safe handling of purchased radioactive material and irradiating apparatus from the time of its order/purchase up to its delivery/commissioning to client. Sales company may be involved in the safe return of unused radioactive materials to it original supplier/producer. Introduction

National Committee for the Certification of Radiation Protection Officer Licenses for vendor:  Class A for radioactive materials  Class C for irradiating apparatus  Class H for installation/commissioning and maintenance. License requires the licensee to plan and implement steps before, during installation and after commissioning of the machine. Licensing Requirements for Sales Activities

National Committee for the Certification of Radiation Protection Officer Gets approval from AELB. Provides personnel dosimeter e.g. film badge, TLD to the workers. Survey meter is calibrated and in good working condition. Sends the equipment to Nuclear Malaysia for testing if it does not comply with any recognized standard. Put up a proper warning sign. Procedures Before Installation/Commissioning of Nuclear Gauge, Irradiation Facility and Irradiating Apparatus

National Committee for the Certification of Radiation Protection Officer No unauthorized person enters the working area. Measures any radiation leakage and make sure it does not exceed the permissible level. Takes remedial action if the equipment does not comply with the requirements. A commissioning report must be submitted to the AELB within 14 days after commissioning has been completed. Procedures Before Installation/Commissioning of Nuclear Gauge, Irradiation Facility and Irradiating Apparatus

National Committee for the Certification of Radiation Protection Officer Licensee must ensure that:  Approval from AELB is obtained for such activity.  Personnel are provided with proper dosimeter e.g. film badge, TLD etc.  Survey meter is calibrated and in good working condition. Procedures Before Maintenance of Nuclear Gauge, Irradiation Facility and Irradiating Apparatus

National Committee for the Certification of Radiation Protection Officer Worker involves in this job must ensure that:  A barrier and a proper warning sign are installed.  Unauthorized person barred from entering work area.  Irradiating apparatus is “OFF” and the shutter of nuclear gauge is closed.  Level of any radiation leakage is continuously monitored.  Exposure records received are kept.  Remedial action taken for non-compliance with the requirements. Procedures During Maintenance of Nuclear Gauge, Irradiation Facility and Irradiating Apparatus

National Committee for the Certification of Radiation Protection Officer Licensee shall:  Keep all records on exposures and maintenance.  Submit a maintenance report to the AELB within 30 days after completion of work. Procedures After Maintenance of Nuclear Gauge, Irradiation Facility and Irradiating Apparatus

National Committee for the Certification of Radiation Protection Officer A leakage test for irradiating apparatus is carried out to measure radiation leak above the approved level. A leak test is carried out to check on seepage of radionuclide from sealed source. Both tests shall be carried out before radioactive source or irradiating apparatus is used and annually thereafter. These tests must be carried out by a competent person. Leakage Test and Leak Test

National Committee for the Certification of Radiation Protection Officer The following safety steps must be complied with:  Install adequate barrier and warning signs.  All the personnel involved must wear a personnel dosimeter.  Use a calibrated survey meter to measure radiation level on the nuclear gauge. Procedures During Leak Test

National Committee for the Certification of Radiation Protection Officer All the radioactive materials imported by the vendor before delivery to the users or the depleted radioactive materials taken from the users to be sent back to the manufacturer shall be stored in the proper storage. Storage of Radioactive Material

National Committee for the Certification of Radiation Protection Officer The design of the storage and it location must be approved by AELB. The storage must have clear and visible radiation hazards warning signs and notices. Inventory of the source stored in the storage facilities shall be kept and maintained. Only authorized staff can enter the storage facilities. The store doors must always be locked and the key kept by RPO. Storage Facilities Requirements

National Committee for the Certification of Radiation Protection Officer Controlled area :  Area that requires specific protective measures or safety provisions to control normal exposures or preventing spread of contamination during normal working conditions. Supervised area :  Area that normally does not requires protective measures to control exposure but under certain conditions may require protective measure and prevention of contamination during normal working conditions.
