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


Downtown Radiation Safety Map

Location of labs using radioisotopes on the MacDonald McGill campus


Macdonald Radiation Locations Map


Major spills

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

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:

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.

5. Monitoring

5.1 General Principles

Monitoring is an essential component of any radiation safety program. It involves the regular and routine measurement and/or assessment of factors relevant to radiation safety and takes the following forms:

6. Use of unsealed radioisotopes in teaching & research

6.1 GENERAL

The Internal Permit Holder must ensure that only persons properly trained and informed of the hazards involved are allowed to handle radioisotopes. In the case of undergraduate students, handling should be limited to sources of a type and activity commensurate with the knowledge and training of the students at a any given stage of their academic careers. A copy of the Internal Permit shall be prominently displayed in each laboratory in which unsealed radioisotopes are stored and/or used.
