Radionuclide Hazards

This video is an excellent demonstration of the safe use of radioactive material in a research laboratory. It is applicable to both new and experienced users of radioactive material.

This training also does not fulfill training requirements for persons who use open sources of radioactivity, which is the form used in most biomedical research.

Contact the Radiation Safety Office (RSO) at 206.543.0463 for information about other radiation safety training available.


This video promotes radiation safety. Random primer labeling for southern hybridization is used to demonstrate the safety principles that apply to the use of radioisotopes in the modern biology laboratory. This video will introduce new staff to good laboratory practices and provide a meaningful technical review in safety for the more experienced laboratory worker. 

"Respect is something that you really want to gain for radioactivity. It's certainly something you wouldn't want to carry out of the laboratory and expose other people to. The thing to keep in mind is that you can contain it and, if you're practicing safe techniques, you are going to have less of a chance of contaminating yourself or a piece of equipment."

Laura G. Brown
Research Technician, HHMI

Whenever working with radiation, keep yourself safe by observing these principles:

  • Know your isotopes
  • Practice ALARA.
  • Time - Distance - Shielding to reduce dose.
  • Use protective equipment.
  • Perform correct monitoring.
  • Know your protocol.
