Working with Ionising radiation

Three types of sources of ionising radiation are used at the University: open sources, sealed sources, and x-rays.  There are different risks and procedures for each type and you need to understand them in relation to the kind of source you will be using in order to keep yourself and others safe.


  • Ionising radiation is radiation that has the power to charge (ionise) atoms.
  • In the human body this ionisation can cause adverse health effects such as the induction of cancer.  The risk of an adverse health effect is related to the level of exposure to radiation and the risks are therefore controlled by limiting the exposure of workers to radiation.
  • In the University this is done by using appropriately designed facilities and equipment, safe working procedures and the training of workers.

There are stringent procedures which you must follow if you are using ionising radiation. You can find these at the Radiation Protection website.

Contact the Radiation Protection Manager if you need any guidance or advice.
