Medical Surveillance - Radiation Lasers

Use of Class 3b or Class 4 lasers may occur within research, teaching, clinical and operational activities at the University of Guelph.  In accordance with regulatory requirements prior to using Class 3b or 4 lasers, prospective users must undergo a pre-assignment (baseline) ocular examination conducted by an optometrist or ophthalmologist.  Occupational Health and Wellness (OHW) will requisition and provide information to users to take to the optometrist / ophthalmologist.   Baseline results must be received by Occupational Health and Wellness prior to any work with a Class 3B or Class 4 laser begins.  As a regulatory requirement it is mandatory that all those identified to do so participate in the laser medical surveillance program.

Medical Surveillance - Radiation Radioiodine

Use of radioiodine such as I-125 or Iodine-131 may occur within research, and clinical activities at the University of Guelph as permitted by licenses issued by the Canadian Nuclear Safety Commission (CNSC).  As a condition of these regulatory licenses monitoring of the thyroid of any personnel using I-125 or I-131 and meeting the prescribed criteria is required.   Thyroid monitoring is to be done prior to an individual initially beginning work with I-125 or I-131 radioiodine and meeting the aforementioned criteria and then between 24 hours to 5 days following each use or potential exposure.  Thyroid monitoring will be performed in Occupational Health & Wellness.  Users of I-125 and I-131 that meet the prescribed criteria are identified through the internal University radiation safety permitting process.  As a CNSC license condition it is mandatory that all those identified to do so participate in the radioiodine medical surveillance program. 

For further information and a comprehensive outline of the program please refer to the Medical Surveillance-Radioiodine module.   Occupational Health and Wellness can also be contacted by phone at 519-824-4120 ext. 52647 or by email.
