What is industrial radiography?

Radiography sources of considerable energy are used by contracted workers to estimate concrete thickness and safety for concrete drilling in University buildings. To perform radiography a work permit must first be approved by the Radiation Protection Service: http://www.ehs.utoronto.ca/Assets/ehs3/rad/Radiography+System.pdf. Part of the approval process is to ensure that everybody within the possible range of irradiated area is informed ahead of the scheduled irradiation. 10. We need to ship some radioactive material to another university. What do I do? Answer: Planning ahead is very important for this action: Please complete the form found at: http://www.ehs.utoronto.ca/Assets/ehs3/rad/RadTransferring.pdf, and fax it to 416-971-1361 at least 5 days ahead of planned shipment. Some shipments abroad require an export permit (like shipping H-3 in any quantity). Please allow a few months for this kind of shipment.  more
