Provides information on receiving Class 7 Radioactive Material Acts as a refresher for staff working in areas where radioactive material is received Serves as part of a radiation safety orientation program for new employees 2 Slide 3 K EY O BJECTIVES Understand the shipping and delivery requirements for Class 7 Radioactive Packages. Identify the requirements of an initial inspection before opening a radioactive package. Use proper radiation safety practices when opening radioactive packages. Understand the requirements for record keeping. Identify the required regulatory reporting requirements when receiving radioactive packages. 3 Slide 4 R ECEIVING C LASS 7 P ACKAGES 4 All photos are CDHA Photos Slide 5 5 CDHA Photo Receiving Requirements Shippers are required to package and provide the following for each Class 7 shipment. Approved Shipping Container Correct TDG Package Type (UN and Excepted or Type A Package) Correct Labels radiation warning shipping address packing documents Identified Isotopes and Activity Limits Slide 6 R ECEIVING R EQUIREMENTS No person, other than the consignor or the consignee of the package, shall open the package unless.... a) measures are taken to prevent persons from receiving doses higher than the radiation dose limits prescribed by the Radiation Protection Regulations b) the package is opened in the presence of an expert in radiation protection (someone authorized and trained to open the package) http://nuclearsafety.gc.ca/eng/ Section 21.(1) Packaging and Transport of Nuclear Substances Regulations 6 Receivers are required to follow the regulations for all Class 7 shipments Section 21.(1) Packaging and Transport of Nuclear Substances Regulations Slide 7 R ECEIVING R EQUIREMENTS 7 Specific receiving procedures are described in the Canadian Nuclear Safety Commission INFO Document http://nuclearsafety.gc.ca/eng/ Identifying and Opening Radioactive Packages, INFO - 0426 rev 1 This should be posted where the package is opened Slide 8 8 Receiving Requirements Procedures must be in place to ensure all Class 7 Packages are..... Delivered to the department without delay Stored securely until received (opened) Received (opened) only by authorized personnel Properly secured and stored after receiving (opening) Photo: Dalhousie University with permission Clip Art: CDHA MS Clip Art File Slide 9 Follow the Canadian Nuclear Safety Commission INFO Guide 0426 rev1 Identifying and Opening Radioactive Packages 9 Opening a Package Slide 10 10 Opening a Package CDHA Photo Verify Address Before signing for the package, verify if it is for your department. If not, then do not accept the package. If you sign, and it is not for you, you are responsible for the package. This could cause problems if you sign for a package and the hospital does not have the isotope on their licence. Worth repeating Slide 11 11 Opening a Package Photo: Dalhousie University with permission Deliver Store Promptly You may take direct receipt from a courier during daytime deliveries. Procedures for after hours receipt of a shipment, by security, includes examination for any damage or leaks and signing for the package. Once signed for, the package is delivered to an after hours holding area. The department responsible for the package is to pick it up the next day. Slide 12 12 Opening a Package Photo: Dalhousie University with permission Check for Damage Perform a visual inspection of the shipping container for any evidence of damage, leakage or tampering. If the package is damaged, tampered with or leaking, stop all receiving and implement emergency procedures. Also notify the Radiation Safety Officer. Slide 13 13 Opening a Package Photo: Dalhousie University with permission Open Package in Designated Area Use a fume hood if the material is volatile such as iodine Open package behind appropriate shielding for a high level of activity Use a bench top in a designated radiation work area Slide 14 14 Opening a Package Photo: Dalhousie University with permission Use Personal Protective Equipment Wear appropriate Personal Protective Equipment (PPE) for the shipment received such as... buttoned lab coat The ring is to be worn under the gloves to protect it from contamination. CDHA Photo personal whole body or ring badge disposable gloves Slide 15 15 Opening a Package Verify Package Dose Rate If a survey meter is available, monitor the dose rate at the surface and 1metre around the package and note any discrepancies with the shipping documents. CDHA Photo Most nuclear substance labs only have contamination monitors available so external monitoring is not required. Slide 16 16 Opening a Package Photo: Dalhousie University with permission Verify Package Contents Once the package has been opened verify the nuclear substance, the quantity and other details with the information on the packing slip and with the purchase order. Slide 17 17 Measuring Contamination The Wipe Test Slide 18 18 Photo: Dalhousie University with permission Prepare, in advance, any material to conduct your wipe test such as filter paper, Q-tips or alcohol swabs; tongs; numbered counting vials; and water or alcohol if using dry swabs. Measuring Contamination Slide 19 19 It is acceptable to use one wipe to check for contamination on the primary container (vial) If no contamination is present, you can log in the shipment, store the vial and dispose of the packaging Some practices use one wipe to test all package components and if it is contaminated repeat the procedure with separate wipes for each package component. Still others wipe all package components with separate wipes Photo: Dalhousie University with permission Measuring Contamination Slide 20 20 The minimum required by regulations is to wipe the exterior surface of the primary container and all six sides of the outer container. The CNSC has clarified that it is expected that the wipe includes all six sides of the container for contamination. * may need to hold container with tongs if a high beta or gamma emitter or required by department procedure Measuring Contamination Photo: Dalhousie University with permission The primary container is the main component that holds the nuclear substance. Generally for liquid vials, it is the glass vial or inside of the lead pot. Slide 21 exterior surfaces of the lead pot 21 interior surface of the lead pot Measuring Contamination Photo: Dalhousie University with permission Other components may be wiped but generally these do not have to be done if the primary container or outside box is not contaminated. Slide 22 You should have a predetermined count rate to meet the wipe test criteria of 4 Bq/cm 2 22 Measuring Contamination Photo: Dalhousie University with permission Ensure that your liquid scintillation, gamma counter or contamination meter are on appropriate settings to count your wipes. Slide 23 23 Measuring Contamination Photo: Dalhousie University with permission A clean or control wipe should also be used as a background count Example: You may know that 340,000 cpm = 4 Bq/cm 2 for P-32 being counted on the well counter in Room 4023. This count may be 260,000cpm on a pancake meter in the lab for the same isotope. Slide 24 24 Finish Receiving The Final Steps Slide 25 Used vials containing the wipe test samples are placed in an appropriate radiation waste storage container to await disposal 25 Photo: Dalhousie University with permission Finish Receiving Waste Disposal Slide 26 If your wipe tests on the package and packing materials are negative any reference to radioactive must be defaced or removed before disposing of packaging. 26 Finish Receiving Discarding Package Material Photo: Dalhousie University with permission Slide 27 27 With both hands gloved, peel one glove off from top to bottom and hold it in the gloved hand With the exposed hand, peel the second glove off from the inside, tucking the first glove inside the second Dispose of the gloves promptly Never touch the outside of the glove with bare skin and wash hands as soon as possible All Photos: Dalhousie University with permission Finish Receiving Glove Removal Slide 28 R ECORD K EEPING /I NVENTORY L OG 28 Monitor and remove gloves used to open the package before continuing with next steps Slide 29 R ECORD K EEPING /I NVENTORY L OG Requirements of Receiving Record Date Packaged Received Name of Supplier Name of Shipper Shipping Document Number Inventory Entry Isotope Name, Activity, Chemical Form, Lot Number.

The end.....now you can do the quiz When in doubt call your supervisor You will never be in trouble for asking questions or asking for help when it comes to radiation safety.
