1 Radionuclide Safety and Methodology Course DAY 2 “The More Practical Stuff”

2 Review – Day 1 Regulations, Legislation & Responsibilities –CNSC, RSO Historical Context Isotopes & Ionizing Radiation: –Alpha, beta, gamma, X-ray, positrons, annihilation reactions –Ionizing vs non-ionizing reactions

3 Review – Day 1 Radioactive Decay Principles –Useful today: disposal & record keeping Units of Measurement –Becquerel: dps –Gray: absorbed dose –Seivert: dose equivalent. Instruments of Measurement –Dosimeters –Survey: GM & Scintillation –Indirect: Scintillation & Gamma

4 Review – Day 1 Doses & Maximums –NEW vs. Public –Women vs. Men? Effects of Ionization Radiation on Biological Systems –Acute Vs. Chronic –Stochastic Effects? –Tissue & Individual Specifics?

5 Reminder: Memorize for the exam: –2 isotopes: half-life energy (keV) type of emission Required shielding –Table 1, Table 4- shielding - Manual

6 This Section: Purchasing Shipping & Receiving Documentation Contamination Control Permits Annual Inventory Report

7 RECORD KEEPING Radiation Sources in the Workplace

8 RECORD KEEPING 1.PURCHASING RADIATION 2.UBC RADIATION DATASHEET - Receiving radiation - Using radiation - Contamination control - Disposal

9 PURCHASING RADIATION - What you Need to know - Exemption quantities no longer apply! All purchases of nuclear materials must be made through the radiation purchasing system.

10 PURCHASING RADIATION - What you Need to know - License Restrictions Web-based Purchasing

11 PURCHASING RADIATION - What you Need to know - UBC LICENSE RESTRICTIONS –Issued by the CNSC –Sets Maximum UBC Possession Limits –Defines UBC License Restrictions

12 PURCHASING RADIATION - What you Need to know - UBC LICENSE RESTRICTIONS -Radiation use must first be OK’d by the UBC Radiation Safety Office (any amount) WHY??? -UBC might not be allowed to have it!

13 PURCHASING RADIATION - What you Need to know - UBC Web-based Purchasing System

14 PURCHASING Who needs to use it? - All UBC Permit Holders - For any isotope on your permit - For any amount of isotope

22 How does it work? Set-up account prior to ordering Check “send order by ” OR fax on- line system receipt Missing Vendors? –Contact HSE to have them added

23 PURCHASING RECORDS -All UBC Users- Records you need to Keep: The last page of your online purchase. *Take this with you to receiving when picking up your order.* Your shipment documents

24 RECEIVING CLASS 7 DANGEROUS GOODS  TRAINING  PPE  CHECK THE LABELS  VERIFY BOX for DAMAGE  MONITOR AND SHIELD  FUME HOOD  WIPE TEST  VERIFY CONTENTS  DOCUMENT

25 RECEIVING CLASS 7 DANGEROUS GOODS TRAINING -The person who receives it MUST take this course

26 RECEIVING CLASS 7 DANGEROUS GOODS PPE -Put on gloves to handle the box

27 RECEIVING CLASS 7 DANGEROUS GOODS CHECK THE LABELS Class 7 Radioactive Material (TDG)

28 Contains: Limited activity Minimal detectable radiation on surface (< 5 Sv/h) EXCEPTED PACKAGE

29 Radioactive Material, Excepted Package This package contains radioactive material, excepted package and is in all respects in compliance with the applicable international and national governmental regulations. UN The information for this package need not appear on the Notification to Captain (NOTOC)

30 RADIOACTIVE l Contents______ Activity________ Field on any Surface < 5 Sv/h No Transport Index (TI) 7 RADIOACTIVE I

31 RADIOACTIVE ll Contents______ Activity________ Transport Index Field on any Surface > 5 Sv/h And < 0.5 mSv/h TI > 0 and < 1 7 RADIOACTIVE II

32 RADIOACTIVE lll Contents______ Activity________ Transport Index Field on any Surface > 0.5 mSv/h And < 2.0 mSv/h TI > 1 and < 10 7 RADIOACTIVE III

35 Receiving Class 7 DG Inspect for damage Monitor & Shield Fume hood Wipe test Document

36 RECEIVING CLASS 7 DANGEROUS GOODS INSPECT BOX for DAMAGE If the package is damaged, you don’t have to accept it!

37 RECEIVING CLASS 7 DANGEROUS GOODS MONITOR AND SHIELD 1. Monitor the surface of the package with a Survey Meter 2. Shield package if required (>2.5Sv/hr)

38 RECEIVING CLASS 7 DANGEROUS GOODS FUME HOOD Place the box in a fume hood before opening

39 RECEIVING CLASS 7 DANGEROUS GOODS WIPE TEST Wipe test the surface of the box to check for contamination

40 RECEIVING CLASS 7 DANGEROUS GOODS DOCUMENT Record the results of the wipe tests and the Vial Identifier information

41 µCi or

42 RECEIVING CLASS 7 DANGEROUS GOODS DOCUMENTS -If your shipment has one, keep the Shipper’s Declaration Form for shipments from OUTSIDE Canada -Keep these records for 3 years!

43

44 RECEIVING CLASS 7 DANGEROUS GOODS All Permit Holders!! UPDATE the UBC web-based Purchasing System! -Date Received -Name of person who received it -VIAL ID – unique to the vial.

45 RECEIVING CLASS 7 DANGEROUS GOODS IMMEDIATELY Contact HSE when: 1.You have questions about the package 2.The order is lost or stolen

46 Regulations for Shipping Class 7 Dangerous Goods  Transport Canada (TDG regulations)  Shipments by Road  International Air Transport Authority Regulations (IATA)  Shipments by Air  Transport Packaging of Radioactive Materials Regulations (CNSC)

47 Shipping Class 7 Dangerous Goods Must have specialized training in the shipping of Class 7 Dangerous Goods (NOT this course) Contact HSE for more info.

48 USING UBC Stock vial access –Record user name (First, Last) –Record date (year/month/day) Radioisotope Data Sheets

51 USING UBC Record How Much Activity is Removed –Record either Activity OR Volume used

52 µCi or

53

54 CONTAMINATION UBC With a Survey Meter –Check for Hot Spots Wipe Tests –Mandatory –At the end of the day of each use –Dates must match the date of accessing your stock vial!

55 CONTAMINATION UBC Map Results Date Document user’s FULL Name Background (Negative Control)

56 CONTAMINATION UBC What is considered contaminated?

57 CONTAMINATION UBC UBC Policy 100 cpm > Background

58 CONTAMINATION UBC If > 100cpm above background -Clean -Re-WIPE -Document

60 RADIATION UBC Methods: 1.Decay (for all isotopes with ½-life < 90 days) 2.Drains (aqueous non-toxic) Red Cans (solvent) 3.Combustible Waste (Pathological, Biological only) 4.Non-Combustible Waste (Solid)

61

62 RADIATION UBC  DOCUMENT  How much radioactivity (in MBq)  The method of disposal

63 RECORDS TO RETAIN * All UBC Users *  Purchase Information  Use Information (UBC Radioisotope Data Sheet)  On-hand Amount (inventory) - ongoing  Contamination Control  Disposal (Radioisotope Data Sheet)

64 11. Radioisotope Licensing

65 PERMITS Required by: Any faculty member wishing to - Purchase - Use - Possess/Store - Dispose

66 PERMITS Application Process  Any faculty member at UBC qualifies to apply  An application form is submitted to HSE  It is then reviewed by the UBC Radioisotopes Committee  License is processed & posted in approved building/lab space

67 Lab Classification *Laboratories are classified as Basic, Intermediate or High Level based on the amount of activity that is handled at one time. This is tracked by the purchasing records. *Intermediate and High Level labs require approval by the CNSC. *Be aware that if you are increasing your purchase amounts, you must not exceed the limit set by your lab classification!

68 Example for P-32: Maximum amount to be handled: Basic Level: 34.5 MBq Intermediate: 345 MBq High: 3450 MBq Do not order single quantities >34.5 MBq !

69 PERMITS Amendments Contact HSE BEFORE you make the change!!!

70 PERMITS Amendments If you need to change:  Isotope  Building/Room  Usage  Add  Delete  Increase  Decrease

71 PERMITS Amendments Send a written request to HSE -An will do-

72 Annual Inventory Report UBC reports to the CNSC annually Summary of:  Purchases  Disposal  Possession at end of year  For each isotope on the license

73 Annual Inventory Report UBC Permit Holders report to the RSO annually Summary of:  Purchases  Disposal/transfer  Possession at end of year  For all radioisotopes on permit  By January 31 st of each year

74 Record Keeping/Licensing Summary Purchase Receiving Use Disposal Contamination Control Shipping (when applicable) Amendments Annual Inventory

75 Review this Section: Purchasing Shipping & Receiving Documentation Contamination Control Permits Annual Inventory Report

76 Questions? How much area should be covered for each wipe in a wipe test? When should a work area be tested for radiation exposure and by whom? How do you pay a supplier of radioactive material?

77 Questions? Which type of packaging is the least hazardous to the user? How do you ship class 7 materials? Can anyone receive class 7 materials?

78 Questions? Name the steps when receiving a radioisotope package? When must the annual report be completed?
