Radionuclide Safety and Methodology CourseDAY 2 “The More Practical Stuff”
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
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
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?
Reminder: • Memorize for the exam: • 2 isotopes: • half-life • energy (keV) • type of emission • Required shielding • Table 1, Table 4- shielding - Manual
This Section: • Purchasing • Shipping & Receiving • Documentation • Contamination Control • Permits • Annual Inventory Report
RECORD KEEPING Radiation Sources in the Workplace
RECORD KEEPING • PURCHASING RADIATION • UBC RADIATION DATASHEET - Receiving radiation - Using radiation - Contamination control - Disposal
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.
PURCHASING RADIATION- What you Need to know - License Restrictions Web-based Purchasing
PURCHASING RADIATION- What you Need to know - UBC LICENSE RESTRICTIONS • Issued by the CNSC • Sets Maximum UBC Possession Limits • Defines UBC License Restrictions
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!
PURCHASING RADIATION- What you Need to know - UBC Web-based Purchasing System www.ubc.ca/okanagan/hse/safety/radioisotope.html
PURCHASING Who needs to use it? • All UBC Permit Holders • For any isotope on your permit • For any amount of isotope
How does it work? • Set-up account prior to ordering • Check “send order by e-mail” OR fax on-line system receipt • Missing Vendors? • Contact HSE to have them added
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
