7. Use of sealed sources

7.1 TYPES OF SEALED SOURCES

A sealed radioactive source is a radioisotope that is fully encapsulated in metal or other container such that there is no contact between the radioactive material and the equipment. Sources commonly used in teaching and research are of the following types:

Location of radioisotope laboratories at McGill

Location of labs using radioisotopes on the downtown McGill campus

Location of labs using radioisotopes on the MacDonald McGill campus

Fundamentals of radiation

The atom can be thought of as a system containing a positively charged nucleus and negatively charged electrons which are in orbit around the nucleus.

8. Use of unsealed sources

8.1 General Principles

The use of unsealed radioisotopes regularly gives rise to radioactive waste, which has to be disposed of in a responsible and safe manner. The waste may include residual amounts of the original radionuclide, disposable containers (vials, pipette tips, etc.), partially decayed or surplus sealed sources, contaminated solids and radioactive animals. The disposal procedures are based on the following principles:

Major spills

Major spills involve more than 100 exemption quantities, or contamination of personnel, or release of volatile material.

4. Licensing authorisation

4.1 CNSC LICENCES

The acquisition, possession and use of most radiation sources are subject to licensing by the Canadian Nuclear Safety Commission (CNSC). The University is issued a consolidated radioisotope license by the CNSC that is renewed every 5 years. In turn, the University issues "Internal Permits" to individual users, and this permit is renewed annually by Environmental Health & Safety.

11. Use of radiation sources in teaching: special requirements

11.1 GENERAL CONSIDERATIONS

This section applies in those instances where students in the university (usually undergraduate) may have occasion to handle radioactive materials as part of classroom or laboratory exercises connected with the courses in which they are enrolled. Such activities must be undertaken with the utmost concern for the safety of the students involved and the following conditions must be observed:
