Safety Assessment
1.Wear lab coat, safety glasses and gloves.
2.Handle filter papers used for wipe testing with tweezers.
3. Do not touch or attempt to move the radioactive sources.

The detection of radioactive contamination is a crucial skill whether working in a laboratory, hospital, industrial plant or the wider environment. This practical provides an introduction to contamination monitoring and the assessment of external gamma dose rate. By selection and use of the appropriate monitoring method it is possible to infer the type of radioactive contamination present, approximate activity levels and external dose. The lessons learnt in this session will be carried through to subsequent experiments.
