Precautions with Ionizing Radiation

If a demonstration requires radioactive substances, there is a risk of exposure to ionizing radiations.

· Be sure to limit the time of exposure.

· Maximise the distance between yourself and the radioactive source.

· Always shield the source.

· Be sure to wash your hands after handling both the source and the Lead shielding.

· Ensure that a radiation safety sign is clearly displayed with the demonstration
