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

USING RADIATION @ UBC Stock vial access –Record user name (First, Last) –Record date (year/month/day) Radioisotope Data Sheets
RADIATION DISPOSAL @ UBC DOCUMENT How much radioactivity (in MBq) The method of disposal
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)
PERMITS Required by: Any faculty member wishing to - Purchase - Use - Possess/Store - Dispose
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
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!
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 !

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